By Maureen Anderson on Posted in Dogs,Other diseasesThere were several more reports over the weekend in follow up to the canine influenza outbreak at dog shows in Florida early last week. Unfortunately, but not surprisingly, associated cases were then found in North Carolina, and have now been reported in 11 states, no doubt from dogs that were at the shows in Florida… Continue Reading

By Scott Weese on Posted in Dogs,Other diseasesA few times a year I get questions about tuberculosis (TB) in dogs, typically after a person is diagnosed with active TB and people want to know what the risks are to, and from, their dog. It’s often tough to answer those questions, because there’s limited information available. Risks exist, but how much of a… Continue Reading
By Scott Weese on Posted in Dogs,Other diseasesEvery year or so, there’s a new wave of publicity/paranoia about the risks associated with dogs licking people. Often, it follows a study of bacteria that can be found in the mouths of dogs. It leads to a combination of balanced reports, sensational reports and defensive responses. What is the concern? Dog’s mouths are vats… Continue Reading
By Scott Weese on Posted in Dogs,Other diseasesHot off the presses in the Journal of the American Veterinary Medical Association (JAVMA) is a guidance document aimed at reducing infectious disease risks in a variety of canine group settings. The paper, Risk reduction and management strategies to prevent transmission of infectious disease among dogs at dog shows, sporting events, and other canine group settings (Stull et al,… Continue Reading
By Scott Weese on Posted in Horses,Other diseasesArboviruses (ARthropod-BOrne viruses) are viruses that are spread by insects, often mosquitoes. As I’ve written about recently, mosquito biology and differences in reservoir species mean that mosquito-borne viruses can have quite different patterns of distribution and spread. As is common, the occurrence of West Nile virus infection in horses tends to ramp up in late… Continue Reading

By Scott Weese on Posted in Horses,Other diseases,Vaccination‘Tis the season for mosquitoes, so ‘tis the season for some nasty vector-borne diseases. Few are worse that Eastern Equine Encephalitis (EEE), a viral infection that causes typically fatal disease in horses, and less commonly other species, including people. Cases tend to start mid-summer and peak late summer to fall, depending on the mosquito dynamics… Continue Reading
By Scott Weese on Posted in Other animals,Other diseasesRecent identification of mcr-1, a gene that makes bacteria resistant to colistin (an antibiotic of last resort) raised a lot of concern. Now, there’s another one to be worried about, as a related gene, mcr-2 has been identified (Xavier et al, Eurosurveillance, July 2016). In this study, 105 colistin-resistant E. coli from calves and piglets… Continue Reading

It’s particularly hard with infectious diseases, which tend not to behave as expected. Yet, it’s important to plan surveillance, education and response. One approach is to assess where certain types of problems are more likely to develop. That can help direct resources (time,… Continue Reading
By Scott Weese on Posted in Cats,Dogs,Other diseasesPublic Health England has launched an investigation following identification of leptospirosis in an animal shelter volunteer. Leptospirosis is caused by the bacterium Leptospira, a bug that can be found in a variety of animal species. It’s shed in urine and loves to survive in cool, moist environments, so people and domestic animals are often exposed… Continue Reading
By Scott Weese on Posted in Other diseasesOk, call me risk averse, but traveling to another country to have someone inject me with cells from organs or fetuses of animals isn’t high on my to-do list. I guess that’s a good thing, given the recent article in Morbidity and Mortality Weekly Report describing Q-fever in people from New York who traveled to Germany for… Continue Reading
By Maureen Anderson on Posted in Other animals,Other diseasesA new study from the University of California, Berkeley, has shown a potential link between bovine leukemia virus (BLV) and breast cancer in women (Buehring et al. 2015). The short version is the study analyzed breast tissue from 239 women, and found evidence of BLV exposure in 59% of the samples from women with breast… Continue Reading
By Maureen Anderson on Posted in Birds,Other diseasesPoultry biosecurity is an important practice to limit the spread of disease. There are many viruses, bacteria and parasites that exist that can cause disease in birds. These can spread by direct bird contact or indirect contact with humans, housing and equipment. Some of these pathogens can be zoonotic and pose a human health risk. Pathogens… Continue Reading
By Scott Weese on Posted in Other diseasesI did a consultation today about a dog that illustrates some of the practical challenges to reducing antibiotic use. It was an older dog with a test result that could be consistent with an infectious disease, but one that is also common in healthy animals. The signs of illness that the dog had would have… Continue Reading
By Scott Weese on Posted in Cats,Dogs,Other diseasesI like to write about interesting papers that appear in the medical literature. A problem with that is that it’s often weird cases that get published. So, it’s important to keep things in perspective. Regardless, reports of rare things still provide some insight, as long as people don’t over-react (which, unfortunately, is often the case).… Continue Reading

It’s particularly important for any "snowbirds" who may travel… Continue Reading
By Scott Weese on Posted in Other diseasesAwareness is good. Being proactive is wise. Being paranoid? That’s another story. As this unprecedented Ebola virus outbreak in West Africa continues to expand, many people in North America have journeyed from ignoring it, to considering it a disease that you only get if you’re in Africa, to thinking they need for move to some… Continue Reading
By Maureen Anderson on Posted in Other diseasesOrange County CA is currently experiencing a major outbreak of West Nile infection in people. Since January 94 cases have been confirmed, three of which were fatal, representing nearly a quarter of the 400 cases reported across the country so far this year. The number of cases of infection with a mosquito-borne virus like West… Continue Reading
By Scott Weese on Posted in Other diseasesIt was only a matter of time, so it’s not particularly surprising, but a potentially devastating pig disease has made its way into Ontario. It’s not a concern to people or other animals, but it’s worth mentioning here anyway (both to say it’s not a public health or non-pig health concern, and since it’s a… Continue Reading
By Scott Weese on Posted in Other diseasesLast week, I mentioned the antibiotic use plenary session at the ASM-ESCMID conference on methicillin-resistant staphylococci in animals. The session was designed to discuss the use of "critically important antibiotics" in companion animals – drugs like carbapenems (imipenem, meropenem) and vancomycin, which are used for treating serious multidrug-resistant infections in people as well. After the… Continue Reading
