Study Finds ‘Horse Bug’ in People is Caused by Actual Virus
Being obsessed with horses isn’t ‘a passion’ reveal researchers.
It’s a disease.

Researchers at the Johns Hopkins University School of Medicine in Baltimore have found that a heightened interest in horses and the compulsion to be around them at all times, is linked to the virus Ecus solidamentum.
“We’ve nicknamed the disease the ‘horse bug’,” says the study’s lead author, Dr. Ivan Toride. “But all joking aside, it seems to be a serious affliction that has real repercussions for sufferers.”
The study reports that people infected with Ecus solidamentum lose all rational thought processes when exposed to equines. Sufferers will ignore physical injuries, strained personal relationships and financial troubles just to spend more time with horses. Dr. Toride admits it’s a startling discovery to find a physical cause behind what was once thought to be only a mental affliction.
People generally become infected through mosquito bites, which is why those who already spend time in barns and outdoors with horses seem to be more susceptible. Interestingly, the researchers found infection rates are higher among middle-age women and that they are the most symptomatic when infected. Teenage girls also have a high susceptibility to the virus, but the disease seems to resolve itself in many by the time the girls reach their 20s.
“It’s a multi-faceted disease that will require much more investigation,” says Dr. Toride. “We still don’t understand the exact viral mechanism that affects the brain’s functioning, or why women in particular seem to be more susceptible.”
Anita Notherpony, who was infected with Ecus solidamentum last year, participated in Dr. Toride’s study. In the last 12 months, her behaviour around horses has become more erratic as the virus has spread through her body. “I lost my job because I couldn’t stay away from the barn. When I did go to work, all I did was read articles about horses or look at horses for sale,” she says.
“It started slowly, I thought it was just a new interest at first. But when I spent my entire pay check at the tack store, I began to suspect there was something deeper was at play.”
When Notherpony read about Dr. Toride’s research in an article in a horse magazine, a lightbulb went off. “I just said, ‘this is me.’”
Notherpony immediately contacted the research team for help. “Dr. Toride diagnosed me. At least I now have an explanation for what is happening. I know this disease is ruining my life, but it’s a compulsion I can’t control. I just hope they find a cure.”
Recently, Notherpony secretly sold her husband’s car for a third horse. At the time of this writing, it was unclear if her husband would be able to continue his employment without a way to get to work, leaving them both in a precarious financial situation.
Betraying the seriousness of her disease, a rapidly deteriorating Notherpony didn’t seem to be able to grasp the severity of the situation during an interview with Horse Network. “He’ll just have to find some other way to get to work. I need to buy another saddle next week,” she said.
It’s situations like these that are pushing Dr. Toride and his team to work overtime to find a cure for Ecus solidamentum. “It’s frightening to see how this disease can affect a mind. We can only hope we stumble across a cure soon,” he says.
Three Ways You May Be Inadvertently Putting Your Barn at Risk for Fire
More so than from other tragedies, I find myself physically as well as emotionally affected by these stories. As the horses usually have absolutely no chance of escaping, I think it is probably the horse owner’s worst nightmare.
Emotions aside, in my job as a professional electrician, I am mindful that many of these fires are caused by faulty electrical wiring or fixtures. Over the year,s I have borne witness to my share of potential and actual hazards. Designing a barn’s electrical system to today’s codes and standards is a topic for another day. For today, let’s address what we can do to make the existing horse barn safer.
I can’t cite statistics or studies, but my own experience shows the main safety issues that I am exposed to fall into three general categories:
- Using extension cords in place of permanent wiring
- Exposed lamps in lighting fixtures, and
- Overloading of branch circuits.
The first item I am addressing is extension cords.
I am often asked how extension cords can be UL-listed and sold if they are inherently unsafe. The answer is that cords are not unsafe when used as intended, but become so when used in place of permanent wiring.
The main concern is that most general purpose outlets in barns are powered by 15 or 20 ampere circuits, using 14 or 12 gauge building wiring, respectively. Most cords, however, for reasons of economy and flexibility, are rated for 8 or 10 amperes, and are constructed of 18 or 16 gauge wiring. That’s no problem if you are using the cord as intended—say, powering a clipper that only draws 1 to 4 amperes.
The problem comes when the cord is left in place, maybe tacked up on the rafters for the sake of “neatness.” You use it occasionally, but then winter comes and you plug a couple of bucket heaters into it. When the horses start drinking more water because it’s not ice cold, two buckets become four—or more.
If they draw 2.5 amperes each, you are now drawing 10 amperes on your 18 gauge extension cord that is only rated to carry 8 amperes. The circuit breaker won’t trip because it is protecting the building wiring, which is rated at 20 amperes. A GFCI outlet won’t trip either because the problem is an overload, not a ground fault.
Anyway, next winter, you decide to remove two of the buckets and add a trough outside the stall with a 1500 watt heater, which draws 12.5 amps at 120 volts. If you thought of it, you even replaced the old 18 gauge cord with a 16 gauge one that the package called “heavy duty.” Now the load is 17.5 amperes on a cord that is designed to handle 10 amperes.
In this case, it is possible to overload a “heavy duty” cord by using it at 175% of its rated capacity and never trip a circuit breaker. What has happened is, we’ve begun to think of the extension cord as permanent wiring, rather than as a temporary convenience to extend the appliance cord over to the outlet.
In doing so, we have created an unsafe condition.
Overloaded cords run hot. Heat is the product of too much current flowing over too small a wire. The material they are made of isn’t intended to stand up over time as permanent wiring must. It’s assumed that you will have the opportunity to inspect it as you unroll it before each use.

The second item on our list is exposed lamps (bulbs) in lighting fixtures.
Put simply, they don’t belong in a horse barn. A hot light bulb that gets covered in dust or cobwebs is a hazard. A bulb that explodes due to accumulating moisture, being struck by horse or human, or simply a manufacturing defect introduces the additional risk of a hot filament falling onto a flammable fuel source such as hay or dry shavings.
In the case of an unguarded fluorescent fixture, birds frequently build nests in or above these fixtures due to the heat generated by the ballast transformers within them. Ballasts do burn out, and a fuel source—such as that from birds’ nesting materials—will provide, with oxygen, all the necessary components for a fire that may quickly spread to dry wood framing.
The relatively easy fix is to use totally enclosed, gasketed and guarded light fixtures everywhere in the barn. They are known in the trade as vaporproof fixtures and are completely enclosed so that nothing can enter them, nothing can touch the hot lamp, and no hot parts or gases can escape in the event of failure.
The incandescent versions have a cast metal wiring box, a Pyrex globe covering the lamp, and a cast metal guard over the globe. In the case of the fluorescent fixture, the normal metal fixture pan is surrounded by a sealed fiberglass enclosure with a gasketed lexan cover over the lamps sealed with a gasket and secured in place with multiple pressure clamps.

The last item, overloaded branch circuits, is not typically a problem if the wiring was professionally installed and not subsequently tampered with. If too much load is placed on a circuit that has been properly protected, the result will be only the inconvenience of a tripped circuit breaker.
The problem comes when some “resourceful” individual does a quick fix by installing a larger circuit breaker. The immediate problem, tripping of a circuit breaker, is solved, but the much more serious problem of wiring that is no longer protected at the level for which it was designed, is created.
Any time a wire is allowed to carry more current than it was designed to, there is nothing to stop it from heating up to a level above which is considered acceptable.
Unsafe conditions tend to creep up on us—we don’t set out to create hazardous conditions for our horses.
Some may think it silly that the electrical requirements in horse barns (which are covered by their own separate part of the National Electric Code) are in many ways more stringent than those in our homes.
I believe that it makes perfect sense. The environmental conditions in a horse barn are much more severe than the normal wiring methods found in the home can handle. Most importantly, a human can usually sense and react to the warning signals of a smoke alarm, the smell of smoke, or of burning building materials and take appropriate action to protect or evacuate the occupants. Our horses, however, depend on us for that, so we need to use extra-safe practices to keep them secure.
As I always state in closing my electrical safety discussions, I know that we all love our animals. Sometimes in the interest of expedience, we can inadvertently cause conditions that we never intended. Electrical safety is just another aspect of stable management. I often use the words of George Morris to summarize:
“Love means giving something our attention, which means taking care of that which we love. We call this stable management.”

Diagnose and Track Your Horse’s Health with Your Phone
Carrying a smartphone or tablet is like having a spare brain in your pocket, one that helps you keep track of all the details in your busy life. At the barn, that device can also help you keep your horse healthy.
Health Data in Your Hand
The latest tool for this task is Horse Health Tracker, a smartphone app released by Equine Guelph, the horse-focused education and research center at the University of Guelph in Ontario, Canada. It’s designed to help you monitor vital health information for your horse.
The heart of the app is the Horse Health Check feature. It guides you through a 16-point health checklist that covers the horse from ears to hooves. Videos show you how to monitor heart rate and other vital signs. You can record results as often as you like, even several times a day, which makes this feature important for monitoring a sick horse.
Other features in the app help you determine and record the horse’s body condition score or estimate his body weight. A video library gives you quick access to all the instructional videos presented in the app. The app retains data from each health tool for 13 months and it will generate graphs so you can compare the results over time. Built-in email capability allows you to send the data directly to your veterinarian or others. You can also enter reminders for vet and farrier visits and other appointments. If you want, the app will sync the reminders with your smartphone’s calendar.
Horse Health Tracker is available for download at the App Store and Google Play. The basic version, which is free, allows you to track information for one or two horses. Upgrades ($4.59 to $11.99) can handle as many as 50 horses. Each horse is tracked separately, and you can add pictures taken with your device to the records. A user guide is online at equineguelph.ca.
Five-Minute Parasite Egg Counts
Does your horse need deworming right now or can he wait until fall? Soon a smartphone may help answer that question, thanks to an innovative new fecal-testing system developed in collaboration with scientists at the University of Kentucky.
Current veterinary guidelines call for individualized deworming programs, using fecal testing to determine the best intervals between treatments and to gauge whether the drugs you’re using are effective. The tests look for the eggs of strongyles, ascarids and some other parasites in manure samples. You collect a sample and send it to a lab (directly or through your veterinarian), where a technician prepares a slide, views it with a microscope and manually counts each visible egg with a clicker. This work requires skill and training, and the results take some time. Generally you’ll wait a week to 10 days for the them to come back.

The new system, called Parasight, shortens that time to less than five minutes. This means that vets can use it in the field to get real-time information about parasite loads. The system includes a smartphone app, an imaging unit (a simple device that attaches to a smartphone) and a kit for prepping manure samples. Samples are first treated with chemicals that cause parasite eggs to glow under blue light. Then they are placed in the imaging unit and photographed with a smartphone.
The smartphone app counts the glowing eggs and emails the results to the veterinarian, along with recommendations for treatment. It can distinguish between different types of parasite eggs and is as accurate as traditional lab tests, the developers say. A companion follow-up kit, which gives less detailed information, is intended for horse owners to use in monitoring the effectiveness of treatment.
MEP Equine Solutions, LLC, the Lexington, Kentucky, company that developed the Parasight System, expects to have a commercial version on the market within a year. Last spring, the company was awarded a $100,000 Small Business Innovation Research grant from the U.S. Department of Agriculture to help move the process along. The people behind the company include Chief Scientific Officer and Co-founder Paul Slusarewicz, PhD, an adjunct professor at the University of Kentucky’s Gluck Equine Research Center who focuses on the commercial development of new animal-health technologies. MEP’s other co-founders are company President Eric Hauk, a businessman, and Technical Adviser Martin Nielsen, DVM, PhD, an international expert in parasitology research who is an assistant professor at the Gluck Center.—Elaine Pascoe

Current Breakthroughs in Equine Research
Over the past 30 years the Grayson-Jockey Club Research Foundation has funneled nearly $20 million into studies aimed at improving horse health. This year the effort continues with funding for a dozen new projects in fields ranging from laminitis to lameness diagnosis. A sampling:
Detecting lameness at the gallop: Kevin Keegan, DVM, of the University of Missouri, is developing an objective method (using a calibrated instrument) for detecting obscure, subtle lameness in horses at the gallop. The goal is a low-cost method that can be used in the field to increase understanding of lameness in racehorses.
Deworming and vaccines: While it’s not unusual to deworm and vaccinate horses on the same day, recent findings have raised concerns about possible interactions. Martin Nielsen, DVM, of the University of Kentucky and Gluck Equine Research Center, is investigating whether deworming causes an inflammatory reaction that affects vaccination.
Imaging injured tendons: Horses recovering from tendon injuries are often put back to work too soon and suffer re-injury. Sabrina Brounts, DVM, of the University of Wisconsin–Madison, is exploring a new method developed at the university to monitor healing in the superficial digital flexor tendon. The technique, called acoustoelastography, relates ultrasound wave patterns to tissue stiffness: Healthy tendon tissue is stiffer than damaged tissue.
Detecting laminitis early: Hannah Galantino-Homer, VMD, of the University of Pennsylvania, is investigating possible serum biomarkers (molecular changes in blood) that appear in the earliest stages of laminitis. The goal is to develop tests for these disease markers so that treatment can start when laminitis is just developing, before it’s fullblown and damages the foot.
Other new studies include evaluations of a rapid test for salmonella; investigation of how neurologic and non-neurologic equine herpesvirus 1 (EHV-1) spreads cell-to-cell in the body; an effort to map the distribution of stem cells after direct injection into veins; and more.

Gut Check: A New View from the Inside

Researchers are testing an endoscopic camera, contained in a small capsule and placed directly into the horse’s stomach, to gather imagery of the equine intestinal tract. The capsule sends images to an external recorder, held in place by a harness.
Courtesy, Western College of Veterinary Medicine
Traditionally, veterinarians’ and researchers’ view of the equine intestinal tract has been limited. Endoscopy (inserting through the horse’s mouth a small camera attached to a flexible cable to view his insides) allows them to see only as far as the stomach. While ultrasound can sometimes provide a bigger picture, the technology can’t see through gas—and the horse’s hindgut (colon) is a highly gassy environment.
These limitations make it hard to diagnose certain internal issues and also present research challenges. But the view is now expanding, thanks to a “camera pill” being tested by a team at the University of Saskatchewan, led by Julia Montgomery, DVM, PhD, DACVIM. Dr. Montgomery worked with a multi-disciplinary group, including equine surgeon Joe Bracamonte, DVM, DVSc, DACVS, DECVS, electrical and computer engineer Khan Wahid, PhD, PEng, SMIEEE, a specialist in health informatics and imaging; veterinary undergraduate student Louisa Belgrave and engineering graduate student Shahed Khan Mohammed.
In human medicine, so-called camera pills are an accepted technology for gathering imagery of the intestinal tract. The device is basically an endoscopic camera inside a small capsule (about the size and shape of a vitamin pill). The capsule, which is clear on one end, also contains a light source and an antenna to send images to an external recording device.
The team thought: Why not try it for veterinary medicine?
They conducted a one-horse trial using off-the-shelf capsule endoscopy technology. They applied sensors to shaved patches on the horse’s abdomen, and used a harness to hold the recorder. They employed a stomach tube to send the capsule directly to the horse’s stomach, where it began a roughly eight-hour journey through the small intestine.
The results are promising. The camera was able to capture nearly continuous footage of the intestinal tract with just a few gaps where the sensors apparently lost contact with the camera. For veterinarians, this could become a powerful diagnostic aid for troubles such as inflammatory bowel disease and cancer. It could provide insight on how well internal surgical sites are healing. It may also help researchers understand normal small-intestine function and let them see the effect of drugs on the equine bowel.
The team did identify some challenges in using a technology designed for humans. They realized that a revamp of the sensor array could help accommodate the horse’s larger size and help pinpoint the exact location of the camera at any given time. That larger size also could allow for a larger capsule, which in turn could carry more equipment—such as a double camera to ensure forward-facing footage even if the capsule flips.
With this successful trial run, the team plans additional testing on different horses. Ultimately, they hope to use the information they gather to seek funding for development of an equine-specific camera pill.
“From the engineering side, we can now look at good data,” Dr. Wahid explained. “Once we know more about the requirements, we can make it really customizable, a pill specific to the horse.”

Home is Whereever You Are
Recently, I had to move to a new farm. And, if you are anything like me you loathe not only moving but moving your horse. The what-ifs running though my head- what if he won’t load? What if he hits his head? What if he freaks out? (Or to be completely transparent, what if I do?). What if he falls? Etc. Personally, when I am faced with a anxiety provoking situation, I need to have a sense of control however small it is. So, I did what I do best and planned and organized. Everything.
Chance had a bad prior experience with being trailered. Plus, with his age (31) and past health issues my anxiety was at an all time high. It was recommended that I plan to meet him at the new farm instead of being there for loading. Made sense. I scheduled the vet to be there in case medications were needed. And they scheduled a therapeutic trailering service with a large trailer that had an forward unloading ramp. The horse communicator was also scheduled as she knew of Chance’s past experience and did energy work.
The day arrived. I went to the farm early and wrapped Chance’s legs, brought he and Lucky inside, packed up all my stuff, and met with the horse communicator. She did some grounding exercises with Chance and myself. I left when everyone arrived and went to the new farm and unloaded our stuff. About 1 hour later the phone rang and of course, I thought the worse. Chance refused to load even after 2 rounds of medications. Lucky was on the trailer. They requested I come and try. I drove the 30 minutes back to the farm- praying to everyone and anything- that Chance would load. I read some tips on Google (yes, I’m ashamed to admit, while driving). One article suggested doing groundwork to get the horse to pay attention. For example, stop him, make him stand, back up, etc. Once he was listening that is when you try to load. The article went on to say that anger and frustration would not work. Because a horse is in sync with our emotions. And that physically, a horse has stamina that we as humans do not share. However, mentally the horse will give up quicker. Patience. Kindness. Persistence.
I arrived. I followed the advice of the article. I walked him and gave commands. I was cool, collected, firm, and kind. We tried once. He walked part way up the ramp, stopped, and backed up. Again, I did the commands. Tried once more. Same thing. The third time the lady who was there to Trailer him lightly smacked his butt with a crop and suddenly, he was on the trailer! I couldn’t believe it. We quickly shut the doors and off we went.
The trip was about 45 minutes. And, thankfully, uneventful. The trailering company was amazing and patient. I’m beyond grateful for everyone’s help!
Below is information for trailering issues, how-tos, and professionals that can make the transition 10000% easier and, almost, stress free.

Science: When Horses Are in Trouble They Ask Humans for Help, Finds New Study
Research Fellow Monamie Ringhofer and Associate Professor Shinya Yamamoto (Kobe University Graduate School of Intercultural Studies) have proved that when horses face unsolvable problems they use visual and tactile signals to get human attention and ask for help.
The study also suggests that horses alter their communicative behavior based on humans’ knowledge of the situation. These findings were published in the online version of Animal Cognition on November 24.
Communicating with other individuals in order to get information about foraging sites and predators is a valuable survival skill. Chimpanzees, who are evolutionarily close to humans, are especially skilled at understanding others. Studies suggest that chimpanzees distinguish the attentional states of other individuals (seeing or not seeing), and they are also able to understand others’ knowledge states (knowing or not knowing).
Some domestic animals are also very good at communicating with humans—recent studies of dogs have revealed that they are excellent at understanding various human gestures and expressions. It is thought that these abilities were influenced by the domestication process.
Since they were domesticated 6000 years ago, horses have contributed to human society in various shapes and forms, from transport to companionship. Horse-riding has recently drawn attention for its positive effects on our physical and mental health. The high social cognitive skills of horses towards humans might partially explain why humans and horses have a collaborative relationship today. However, the scientific evidence for this ability is still scarce.
In this study, scientists investigated horses’ social cognitive skills with humans in a problem-solving situation where food was hidden in a place accessible only to humans. The experiment was carried out in a paddock belonging to the equestrian club at Kobe University, where eight horses from the club participated with the cooperation of their student caretakers.
For the first experiment, an assistant experimenter hid food (carrots) in a bucket that the horse could not reach. The researchers observed whether and how the horse sent signals to the caretaker when the caretaker (unaware of the situation) arrived. The horse stayed near the caretaker and looked at, touched, and pushed the caretaker. These behaviors occurred over a significantly longer period compared to cases when they carried out the experiment without hiding the food.
The results showed that when horses cannot solve problems by themselves they send signals to humans both visually (looking) and physically (touching and pushing).
Building on these results, for the second experiment they tested whether the horses’ behavior changed based on the caretakers’ knowledge of the hidden food. If the caretaker hadn’t watched the food being hidden, the horses gave more signals, demonstrating that horses can change their behavior in response to the knowledge levels of humans.
These two experiments revealed some behaviors used by horses to communicate demands to humans. They also suggest that horses possess high cognitive skills that enable them to flexibly alter their behavior towards humans according to humans’ knowledge state. This high social cognitive ability may have been acquired during the domestication process.
In order to identify the characteristic that enables horses to form close bonds with humans, in future research the team aims to compare communication between horses, as well as looking more closely at the social cognitive ability of horses in their communication with humans.
By deepening our understanding of the cognitive abilities held by species who have close relationships with humans, and making comparisons with the cognitive abilities of species such as primates who are evolutionarily close to humans, we can investigate the development of unique communication traits in domesticated animals.
This is connected to the influence of domestication on the cognitive ability of animals, and can potentially provide valuable information for realizing stronger bonds between humans and animals.

Immune Booster Leads to Infection?
For the past 6 weeks, my horse has been receiving Ozonetherapy to aid in his chronic back leg related issues- dermatitis (“scratches”), previous DDFT tendon laceration, a history of Lymphingitis, and the residual scar tissue from his DDFT injury. Due to his age (27), he lacks proper circulation in his hind end which does not help him fight his pastern dermatitis.
According to the American Academy of Ozonetherapy, Ozonetherapy is described as;
“Ozonotherapy is the use of medical grade ozone, a highly reactive form of pure oxygen, to create a curative response in the body. The body has the potential to renew and regenerate itself. When it becomes sick it is because this potential has been blocked. The reactive properties of ozone stimulate the body to remove many of these impediments thus allowing the body to do what it does best – heal itself.”
“Ozonotherapy has been and continues to be used in European clinics and hospitals for over fifty years. It was even used here in the United States in a limited capacity in the early part of the 20th century. There are professional medical ozonotherapy societies in over ten countries worldwide. Recently, the International Scientific Committee on Ozonotherapy (ISCO3) was formed to help establish standardized scientific principles for ozonotherapy. The president of the AAO, Frank Shallenberger, MD is a founding member of the ISCO3.”
“Ozonotherapy was introduced into the United States in the early 80’s, and has been increasingly used in recent decades. It has been found useful in various diseases;
- It activates the immune system in infectious diseases.
- It improves the cellular utilization of oxygen that reduces ischemia in cardiovascular diseases, and in many of the infirmities of aging.
- It causes the release of growth factors that stimulate damaged joints and degenerative discs to regenerate.
- It can dramatically reduce or even eliminate many cases of chronic pain through its action on pain receptors.
- Published papers have demonstrated its healing effects on interstitial cystitis, chronic hepatitis, herpes infections, dental infections, diabetes, and macular degeneration.”
After doing research and speaking to one of my good friends, we determined that Chance’s flare up of Lymphingitis, after almost 3 years of not a single issue, could possibly be caused by his immune system’s response to Ozonetherapy. Let me explain.
Chance suffers from persistent Pastern dermatitis (“scratches”) since I purchased him in 2000. I have tried everything- antibiotics, every cream and ointment and spray for scratches, diaper rash ointment, iodine and vaseline mix, Swat, laser treatments, scrubs and shampoos, shaving the area, wrapping the area, light therapy…you name it, I have tried it. So, when we began Ozonetherapy to help break down the left over scar tissue from his old DDFT injury, I noticed that his scratches were drying up and falling off. We continued administering the Ozonetherapy once a week for about 6 weeks. The improvement was dramatic!
However, one day Chance woke up with severe swelling in his left hind leg and obviously, he had difficulty walking. He received Prevacox and was stall bound for 24 hours. The vet was called and she arranged to come out the following day. The next morning, Chance’s left leg was still huge and he was having trouble putting weight on it. I did the typical leg treatments- icing, wrapping. The swelling remained. I tried to get him out of his stall to cold hose his leg and give him a bath but he would not budge. He was sweaty and breathing heavily and intermittently shivering. So, I gave him an alcohol and water sponge bath and continued to ice his back legs. I sat with him for 4 hours waiting for the vet to arrive. He had a fever and wasn’t interested in eating and his gut sounds were not as audible. He was drinking, going to the bathroom, and engaging with me. I debated giving him Banamine but did not want it to mask anything when the vet did arrive.
The vet arrived, gave him a shot of Banamine and an antihistamine and confirmed that Chance had a fever of 102 degrees and had Lymphingitis. There was no visible abrasion, puncture, or lump… I asked the vet to do x-rays to ensure that he did not have a break in his leg. The x-rays confirmed that there was no break. The vet suggested a regiment of antibiotics, steroids (I really am against using steroids due to the short-term and long-term side effects but in this case, I would try anything to make sure he was comfortable) , prevacox, and a antacid to protect Chance from stomach related issues from the medications. It was also advised to continue to cold hose or ice and keep his legs wrapped and Chance stall bound.
The following day, Chance’s legs were still swollen but his fever had broken. The vet called to say that the CBC had come back and that his WBC was about 14,00o. She suggested that we stop the steroids and do the antibiotic 2x a day and add in Banamine. I asked her if she could order Baytril (a strong antibiotic that Chance has responded well to in the past) just in case. And that is what we did.
Being as Chance had such a strong reaction to whatever it was, I did some thinking, discussing, and researching…first and foremost, why did Chance have such an extreme flare up of Lymphingitis when he was the healthiest he has ever been? And especially since he had not had a flare up in 3+ years…plus, his scratches were getting better not worse. The Ozonetherapy boosted his immune system and should provide him with a stronger defense against bacteria, virus’, etc. So why exactly was he having a flare up? And that is when it hit me!
In the past when Chance began his regiment of Transfer Factor (an all natural immune booster), he broke out in hives. The vet had come out and she felt it was due to the Transfer Factor causing his immune system to become “too strong” and so it began fighting without there being anything to fight, thus the hives. My theory- Chance started the Ozonetherapy and his body began to fight off the scratches by boosting his immune system. As the treatments continued, his immune system began to attack the scratches tenfold. This resulted in his Lymphatic system to respond, his WBC to increase, and his body temperature to spike. Makes sense…but what can I do to ensure this is not going to happen again?
My friend suggested attacking the antibiotic resistant bacteria by out smarting them…okay, that seems simple enough…we researched the optimal enviroments for the 3 types of bacteria present where Chance’s scratches are (shown in the results of a past skin scape test). The bacteria – E. Coli, pseudomonas aeruginosa and providencia Rettgeri. The literature stated that PA was commonly found in individuals with diabetes…diabetes…SUGAR! How much sugar was in Chance’s feed? I looked and Nutrina Safe Choice Senior feed is low in sugar…so that is not it. What else can we find out? The optimal temperature for all three bacteria is around 37 degrees celsius (or 98.6 degrees fahrenheit), with a pH of 7.0, and a wet environment. Okay, so, a pH of 7.0 is a neutral. Which means if the external enviroment (the hind legs)pH is thrown off, either to an acidic or alkaline pH, the bacteria will not have the optimal enviroment to continue growing and multiplying. How can I change the pH?
Vinegar! An antimicrobial and a 5% acetic acid! And…vinegar is shown to help kill mycobacteria such as drug-resistant tuberculosis and an effective way to clean produce; it is considered the fastest, safest, and more effective than the use of antibacterial soap. Legend even says that in France during the Black Plague, four thieves were able to rob the homes of those sick with the plague and not become infected. They were said to have purchased a potion made of garlic soaked in vinegar which protected them. Variants of the recipe, now called “Four Thieves Vinegar” has continued to be passed down and used for hundreds of years (Hunter, R., 1894).
I went to the store, purchased distilled vinegar and a spray bottle and headed to the farm. I cleaned his scratches and sprayed the infected areas with vinegar. I am excited to see whether our hypothesis is correct or not…I will keep you posted!
