Get Smart About Antibiotics Week

Posted in Cats, Dogs, Horses, Miscellaneous, Other animals
Since their discovery in the mid-1900s (which really wasn’t that long ago in the grand scheme of things), antibiotics have revolutionized human medicine, veterinary medicine and even food production.  They save lives and prevent illness, helping to make both people and animals healthier, happier and more efficient at what they do.  But if we want… Continue Reading

Equine anaplasmosis: Ontario

Posted in Horses
Another Ontario issue to report: this one is in a horse. Recently, a case of anaplasmosis was identified in a horse in Eastern Ontario. People in some places may say “so what?” The reason it’s noteworthy is that anaplasmosis has historically been a very rare disease in Ontario. It’s a infection caused by the bacterium Anaplasma… Continue Reading

Tick ID card

Posted in Cats, Dogs, Horses
Knowing your ticks is important. Certain ticks are able to transmit certain diseases, so knowing what to look for, on yourself and your animals, is useful. To help with that, Wellington Dufferin Guelph Public Health has released a quick-reference Tick ID Card.  When folded in half, it’s about the size of a business card, so… Continue Reading

Ontario eastern equine encephalitis update

During today’s Canadian Equine Infectious Disease Surveillance call, Dr. Alison Moore from the Ontario Ministry of Agriculture Food and Rural Affairs gave an update on equine infectious neurological disease cases in the province. Prominent amongst those disease is eastern equine encephalitis (EEE). This very mosquito-borne viral infection is fortunately pretty rare in horses and is… Continue Reading

Equine infectious disease podcasts

This summer, we started a monthly Canadian Equine Infectious Disease Surveillance teleconference series to provide quick periodic updates on various infectious disease issues and outbreaks to/from provincial, territorial and federal regulatory animal health officials, academia, practicing veterinarians and industry partners. Recordings of some of the calls are now available on the Equine Canada website.  … Continue Reading

The Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) has launched its new (and long-awaited) rabies website.  The site includes a section for the public which is an ideal resource for clients, and a section for veterinarians with detailed information about reporting, risk assessment, sample submission and testing, and post-exposure management (for companion animals and… Continue Reading

Equine infectious anemia in Canada

Posted in Horses
A recent cluster of equine infectious anemia (EIA) cases in Saskatchewan highlights the personal side of EIA control. EIA is a serious insect-borne viral disease of horses that can cause illness ranging from mild to fatal. Some horses recover uneventfully but are then potential sources of the virus for others, and disease can build up slowly and silently… Continue Reading

New USEF equine vaccination requirements

Posted in Horses, Vaccination
Mandatory vaccination for horses entering shows, other events and sales has been a surprisingly contentious issue for years. Some groups have required equine influenza vaccination for a long time, and it’s an accepted measure. Attempts to mandate vaccination for some other groups or events have often been met with resistance, even when those attempts were… Continue Reading

West Nile virus in Ontario

Posted in Horses, Vaccination
The season has arrived. Right on schedule, the first case of West Nile virus (WNV)  infection in an Ontario horse has been identified, prompting an advisory from the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA). The affected horse was from Sudbury, Ontario, and was euthanized because of progressive and severe neurological disease. It… Continue Reading

Equine strangles persistence

Posted in Horses
This week, a horse show in Halifax (UK) was cancelled because of some local cases of strangles (Streptococcus equi subsp equi infection). We can debate whether that was prudent or overkill (or whether measures could have been put in place to reduce the risk and make it manageable), but it highlights the concerns that accompany… Continue Reading

Equine herpes alert…Ottawa

Posted in Horses
The Ontario Ministry of Agriculture Food and Rural Affairs has issued a Biosecurity Alert (2015-07-09 EHM advisory) in response to an equine herpesvirus myeloencephalopathy  (EHM) case. This neurological disease, caused by equine herpesvirus type 1 (EHV-1) gets a lot of attention now, when 10 years ago it would have largely been dismissed (or at least… Continue Reading

Equine infectious disease research: Call for Ontario participants

Posted in Horses, Miscellaneous
Are you an Ontario horse owner? University of Guelph researchers now recruiting for new equine project! Horses travel frequently, and the nature and extent of these travel patterns can contribute to the introduction and spread of diseases. The University of Guelph is conducting a study to determine how these movement patterns can influence new disease… Continue Reading

Horses, strangles, streptococcus

Posted in Horses
A paper in the journal BMC Research Notes describes a case of meningitis in a 73-year-old man that was attributed to contact with a horse (Madzar et al 2015). The man was admitted to hospital with fever, headache, neck stiffness, malaise and drowsiness. He was ultimately diagnosed with meningitis caused by Streptococcus zooepidemicus (technically, Streptococcus… Continue Reading

Probiotics…above all, do no harm?

Posted in Horses
Probiotics are popular treatments for any number of ailments (in animals and people), but marketing, especially on the veterinary side, massively outstrips research. A few years ago, I worked on probiotic development in horses. We found what looked like a good candidate bug, but instead of just trying to sell it, we did a proper… Continue Reading

Communication done right: EVH-1 in Minnesota

Posted in Horses
Two cases of EHV-1 have been detected on a farm in Prior Lake, Minnesota.  There aren’t a lot of details about the cases, other than one horse was put down, and the other was taken to the University of Minnesota veterinary hospital for treatment and has apparently recovered and is ready to come home. The… Continue Reading

Equine outbreaks…EHV-1, glanders

Two cases of fatal equine herpesvirus type I (EHV-1) neurological disease have been confirmed in the Dickinson, Texas, area. Three more recent deaths are suspected to be associated with the virus as well. The horses were from two boarding stables that are currently under quarantine, as is a veterinary clinic. As always, there’s a need… Continue Reading

EEE in Ontario 2014

Posted in Horses
2014 was the worst year ever for Eastern Equine Encephalitis (EEE) in Ontario (though our numbers still pale in comparison to more endemic areas in the southern US, such as Florida). A recent article published in the Animal Health Lab (AHL) Newletter (December 2014) by Dr. Alison Moore from OMAFRA sums things up well: "Twenty-two… Continue Reading

The Ontario Ministry of Agriculture Food and Rural Affairs (OMAFRA) has issued an Equine Health Advisory in response to diagnosis of Eastern Equine Encephalitis (EEE) in a horse in Stormont/Dundas/Glengarry, in eastern Ontario. The 12-year-old gelding died, which is the typically outcome with this disease in horses. EEE is a devastating but fortunately rare (at least… Continue Reading

St. Louis encephalitis in a horse

Posted in Horses
Hopefully we can chalk this one up on the "weird and not-so-wonderful" list, and not have it emerge as a significant problem. However, there’s something new to pay attention to as St. Louis Encephalitis virus (SLEV) infection was recently identified in a Brazilian horse with neurological clinical signs. SLEV is a Flavivirus and a relative… Continue Reading

Traveling with your horse…infection control considerations

Posted in Horses
It’s not a coincidence that we see more equine infectious diseases during busy show seasons. Shows are a great way for infectious diseases to spread, with outcomes ranging from disease in single horses to widely disseminated outbreaks, even across international borders. We can’t eliminate all risk in life, and the risk of infection in horses… Continue Reading

West Nile virus in Colorado

Posted in Horses
It’s that time of year again… at least in some areas. West Nile virus (WNV) infection has been identified in a horse in Colorado. It’s not really a surprise. West Nile virus is one of those pathogens that we know is coming back every year, we just don’t know exactly when. The date of return… Continue Reading
