Colistin Resistance in Pets

Posted in Cats, Dogs
I’ve had a lot of emails over the past few months from colleagues from other countries, asking if we’re finding much mcr-1 in Canada. mcr-1 is a gene that makes bacteria resistant to colistin, a “drug of last resort” in people with some highly resistant infections.  The gene has emerged in bacteria from both animals… Continue Reading

Immunocompromised People and their Pets

Posted in Birds, Cats, Dogs, Other animals, Pocket pets, Reptiles
This month’s edition of the Internal Medicine Journal contains an article entitled High rates of potentially infectious exposures between immunocompromised patients and their companion animals: an unmet need for education (Gurry et al. 2017). The study is fairly superficial and there’s nothing particularly surprising in the paper, with results similar to what has been reported in… 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

Rabies and Bite Responses

Posted in Dogs, Rabies, Vaccination
There tends to be confusion about what happens when an animal bites or is bitten, and rabies is being considered. Most of the confusion revolves around how long an animal is quarantined or observed. Yet, it’s actually pretty straightforward if you think about why quarantine/observation is being performed and some basics about the virus and… Continue Reading

2016 Rabies Compendium

Posted in Cats, Dogs, Horses, Other animals, Rabies, Vaccination
The 2016 Compendium of Animal Rabies Prevention and Control has been released by the US’s National Association of State Public Health Veterinarians (NASPHV). This version has updates in a few different areas, such as some changes to recommendations for dogs, cats and ferrets that have potentially been exposed to rabies. It can be downloaded directly here or be found… Continue Reading

Is MRSP zoonotic?

Posted in Dogs, MRSA/MRSP
I’ve written about this many times (probably because I get asked about it almost every day), but there’s not really a simple answer to the question “Does methicillin-resistant Staph. pseudintermedius pose a human health risk?” My typical answer is along the lines of “Yes, but…” with discussion about how rare Staph pseudintermedius (SP) infections are in… Continue Reading

Ontario lungworm update

Posted in Dogs, Parasites
The fox lungworm, Crenosoma vulpis, continues to be identified in dogs in Ontario. The attached map from WormsAndGermsMap shows the cases we know about. There aren’t many, but the issue of “rare vs rarely diagnosed” is important. As a relatively new (or newly identified) problem that requires specific testing, it’s easy for it to be… 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

American Family Physician: Enhancing Patient Care Through Time with Animals

Posted in Dogs
Here’s a case scenario in a “Curbside Commentary” from the journal American Family Physician (Mani and Weese, 2016). A 16-year-old girl and her parents presented to my office for her wellness evaluation. The patient has generalized anxiety disorder with comorbid major depression, for which she has been prescribed a serotonergic antidepressant. She is a high school student,… Continue Reading

Brucella canis and rescue programs

Posted in Dogs
A Wisconsin rescue has its dog population under quarantine after a dog that was adopted from the facility was identified as being infected with Brucella canis. Dogs at Gregory’s Gift of Hope are being tested, and any positives will presumably be euthanized. Littermates of the infected dog, which was adopted in 2015, are being traced… 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 Diseases and Canine Group Settings

Posted in Dogs
The Ohio State University has launched a new website about infectious disease risks in canine group settings. The site includes a comprehensive document on risk and risk reduction strategies (which was just published last month in the Journal of the American Veterinary Medical Association), as well as owner-level fact sheets and a risk calculator to help identify specific risks… Continue Reading

Dog Bite Prevention Education

Posted in Dogs
I spend a lot of time talking about “emerging” infectious diseases. Some of these are truly emerging (i.e. new) diseases, some are conditions we couldn’t diagnose well before but now recognize more easily, and some are disease that have been there all along and are just getting more attention. However, while emerging infectious disease (especially zoonotic… 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

Vague Disease Warning in Dogs (and Cats?) in New Jersey

Posted in Cats, Dogs
A vague but potentially interesting report from New Jersey outlines a request for information about pet deaths in the area. The Cumberland County [New Jersey] Health Department is asking for the public’s help in collecting data on reports of what it calls “sudden and unusual illness” among dogs in the county. Perhaps the most interesting and… Continue Reading

Diagnostic Crotch Sniffing?

Posted in Dogs, Miscellaneous
Dogs’ noses are used for a lot of things. Some are conventional (e.g. tracking, search and rescue, drug detection), some are a bit outside of the box (e.g. detection of Clostridium difficile, identifying floating whale poop). A recent paper in Open Forum Infectious Diseases (Maurer et al 2016) takes this to another level by investigating the… Continue Reading

Guinea Worm in Dogs

Posted in Dogs
There are a lot of gross parasitic diseases. A prime example is dracunculiasis, otherwise known as Guinea worm (Dracunculus medinensis) infection. People get infected by drinking water or eating undercooked fish contaminated with “water fleas” that are infected with Guinea worm larvae. Over a year or so, the worm grows silently in the body, with… Continue Reading

Capnocytophaga Back in the News

Posted in Dogs
Capnocytophaga canimorsus is a bit of an obscure bacterium. When I talk about it to veterinary or physician audiences, I’m usually met with blank stares – not surprising, since it’s not really mentioned in veterinary or medical school, from what I can tell. It’s a rare cause of infection, but a nasty one. The fact that it’s… Continue Reading

Worms and Germs Map Update

Posted in Cats, Dogs, Horses, Parasites, Rabies
A few years ago, we launched WormsAndGermsMap to help track certain emerging and endemic diseases. Data are entered by participating veterinary clinics, surveillance programs and the WormsAndGerms team. While we certainly can’t capture every case, we do collect some interesting information about the presence of certain diseases. Using the “Report Filter” bar on the left, you can… 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

Moving Dogs, Moving Bugs

Posted in Dogs, Rabies, Vaccination
I’ve written a lot about the issues of dog importation and the diseases that can sometimes “come along for the ride”. However, high risk movement doesn’t need to be international. Any movement from a high risk area can be a concern. A recent article in Canadian Communicable Disease Report (Curry et al. 2016) addresses the issue of… Continue Reading

There’s a Test For That! But, Is There a Need?

Posted in Dogs
Some diagnostic tests that are available are more of a situation of a test looking for a market rather than filling a clinical need for additional information. That complicates matters since providing new information isn’t necessarily useful if we don’t know what to do with it. In some situations, it can even lead to bad decisions.… Continue Reading

New superbug in dogs and cats: mcr-1

Posted in Cats, Dogs
A few years ago, the New Delhi metallobetalactamase-1 (NDM-1) antibiotic resistance gene attracted a lot of attention. This resistance gene can be found in (and passed between) a variety of bacteria, and bacteria possessing this gene are resistant to a wide range of drugs. A drug of last resort for those infections is colistin (a… Continue Reading
