WHO Guidelines on Use of Medically Important Antimicrobials in Food-Producing Animals

Posted in Other animals, Other diseases
The World Health Organization has released new guidelines on the use of “medically important antimicrobials” (MIAs) in food animals. Here’s a list of their recommendations, along with the strength of each recommendation and quality of evidence behind it. We recommend an overall reduction in use of all classes of medically important antimicrobials in food-producing animals (Strong… Continue Reading

Antibiotics and dairy calves

Posted in Other animals, Other diseases
From CANresist.blog: Reducing Antibiotic Use in Dairy Calves This topic’s huge, and there’s always a risk of trying to oversimplify the problem or solutions. However, some solutions for some issues might be fairly straightforward. Whether it’s on a farm, in a hospital or in a doctors office, there are situations where I think it’s widely… Continue Reading

Petland Campylobacter outbreak update

Posted in Dogs, Other diseases
The CDC has posted an update on the outbreak of Campylobacter infections in the US linked to puppies from Petland, a pet store chain. Here are the highlights: The case count is now up to 67, in 15 states (see map and graph of case occurrence below). The true number of infected people is unknown, since it’s reasonable… Continue Reading

Piranha bite response

Posted in Other animals, Other diseases
Yes, piranha bite response is a pretty niche topic. Nevertheless, it’s interesting (at least to me). A recent paper in Pediatric Emergency Care (Berkowitz and Goldsmith. An unexpected fish bite. 2017) covers this topic. It starts off this way: A 22-month-old boy presented to the pediatric emergency department with a missing right fourth distal phalanx… Continue Reading

Croc stories, times two

Posted in Other animals, Other diseases
When I think about bad things that can happen from interacting with a crocodile, infectious diseases don’t jump to the top of my list (ingestion and amputation being the two first things that come to mind). That leads me to the first crocodile story (thanks Stephen), a rather light-hearted description that everyone but the bitten… Continue Reading

Campylobacter outbreak from puppies

Posted in Dogs, Other diseases
Cute. Frustrating. Cuddly. Biohazardous All of these apply to puppies. It’s well recognized that puppies (and kittens) pose increased infectious disease risks, for a few reasons. These include a higher likelihood of shedding various pathogens, greater environmental contamination when they poop on the floor (or anywhere else) and a tendency to cause minor bites and… Continue Reading

Psittacosis from a horse

Posted in Horses, Other diseases
I’ve had this paper from One Health (Chan et al 2017) on my “to blog” pile for a while, since it’s an interesting story. Like any case report, it’s a bit of an oddball infection, and not likely indicative of a major or new risk. However, there are often a few good general take-home messages from… Continue Reading

Close encounters of the ‘tick’ kind…Your pet, pathogens & Lyme disease

Posted in Dogs, Horses, Other diseases, Parasites
Guest Blog by Dr. Michelle Evason DVM DipACVIM, and current PhD student researching Lyme disease in dogs Recently, an interesting article on pet ownership and human tick risk was published (Jones et al, Zoonoses and Public Health 2017). The study looked at risk factors for “tick encounters” in people living in Lyme disease endemic states in the… Continue Reading

A perfect storm for canine flu

Posted in Dogs, Other diseases
There 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

Canine and Feline Respiratory Infection Treatment Guidelines

Posted in Cats, Dogs, Other diseases
The latest set of clinical treatment guidelines from the International Society for Companion Animal Infectious Diseases have been published in the Journal of Veterinary Internal Medicine (Lappin et al 2017): Antimicrobial Use Guidelines for Treatment of Respiratory Tract Disease in Dogs and Cats: Antimicrobial Guidelines Working Group of the International Society for Companion Animal Infectious… Continue Reading

Pre-multidrug-resistant TB in a dog

Posted in Dogs, Other diseases
A 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

Dog Licks…Again

Posted in Dogs, Other diseases
Every 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

Infectious Disease Risk Management for Canine Group Settings

Posted in Dogs, Other diseases
Hot 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

Equine Arbovirus Update

Posted in Horses, Other diseases
Arboviruses (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

Eastern Equine Encephalitis Season in Full Swing

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

Move Over mcr-1. You’re Old News.

Posted in Other animals, Other diseases
Recent 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

Mapping Zoonotic Disease Emergence Risk

Posted in Birds, Cats, Dogs, Horses, Other animals, Other diseases, Pocket pets, Reptiles
Predicting the future is a dodgy proposition at the best of times. 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
