Canine leptospirosis maps

Posted in Dogs, Other diseases, Vaccination
I’ve had a few discussions with people over the past week about geographic variation in disease risk. It’s a great subject because it’s an important and often overlooked issue. Whether it’s animals being imported, animals moving with their owners, animals accompanying owners on vacation or animals being moved between regions within the county, movement between… Continue Reading

Leftover zoonotic disease Q&A, Part 1

Posted in Cats, Dogs, Rabies
I did a talk recently for Third Age Learning in Guelph, and there was an abundance of questions. I didn’t get through them all at the time, so I figured I’d address some of them here: Do mice carry rabies? Mice aren’t rabies reservoirs like raccoons, skunks or bats, as they don’t have a rabies… Continue Reading

Dog parks and canine leptospirosis

Posted in Dogs, Vaccination
A Fremont, California dog park was temporarily closed in response to concerns about canine leptospirosis after 4 reports of dogs contracting the disease, potentially associated with exposure at the park. It’s always hard to determine the source of exposure with lepto, but a park is certainly possible. We don’t understand a lot about how and where… Continue Reading

When bugs don’t read the books

Posted in Cats, Dogs
Minus 20C weather is supposed to have some benefits – at least that’s what we try to tell ourselves. (Maybe we’re just trying to justify why we haven’t migrated south.) I’ve written about leptospirosis a few times recently, given the horrible lepto season we’ve been having. This bacterial disease isn’t new, but there have been… Continue Reading

Leptospirosis from Puerto Rico hurricane dogs

Posted in Dogs
When Puerto Rico was devastated this fall by Hurricane Maria, I got a few calls from groups thinking about rescuing dogs from the island, and wanting to know what infectious diseases I’d be concerned about. Leptospirosis, a potentially serious bacterial infection that can be transmitted from dogs to people (although that’s fortunately uncommon), was at… Continue Reading

‘Tis the season for leptospirosis in dogs

Posted in Dogs, Vaccination
Leptospirosis is a potentially nasty bacterial infection that can cause severe kidney disease (among other things) and is acquired from the environment, in cool damp areas that are contaminated with urine from infected reservoir hosts (e.g. rats, raccoons, other wildlife). It can also potentially be transmitted to people through contact with urine from an infected… 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

Things not to do with raccoons

Posted in Parasites, Rabies
1) Pick up baby raccoons and take them away Rarely does this end well. It’s illegal in many areas (including Ontario). Raccoons don’t do well long-term in households for various reasons (their curious and destructive nature being a big one). And, they are potential sources of a number of zoonotic diseases (rabies being a big one but not… Continue Reading

Leptospirosis vaccination risks

Posted in Dogs, Vaccination
Vaccination discussions can get pretty heated. It’s not as bad with animals as with humans (thanks in part to the discredited (and formerly Dr.) Andrew Wakefield). Yet, there is still a reasonable number of people who are opposed to vaccination of pets, and probably a bigger number who are wary. There are various reasons for… Continue Reading

Leptospirosis in dogs…risks and costs

Posted in Dogs
Leptospirosis is a bacterial infection that’s been described as a re-emerging problem in dogs in North America. (It’s been described as that for many years now so maybe we should drop the "re-emerging" and just say it’s a problem). The causative agent, Leptospira interogans, is a widespread bug that’s carried by a variety of wildlife… Continue Reading

Lepto risk factors and research musings

Posted in Dogs
Studies that look at risk factors can be pretty variable in terms of what they tell you, the impact they have and how accurate they are. Some findings are pretty logical, clear and indicate something that should be done. Smoking is a risk factor for [insert many diseases here], so to reduce the risk of… Continue Reading

To lepto or not to lepto…

Posted in Dogs
Life with Merlin has been busy but going pretty well. There’s been no pee on the floor in the past 48 hours so we’re making progress. Speaking of pee (which, sadly, I seem to do a lot), we need to decide about leptospirosis vaccination for Merlin. A good preventive medicine program is important for every pet.… Continue Reading

Boy Scouts not so prepared this time

Posted in Other animals
Earlier this year, a troop of Boy Scouts in the US beat off a rabid beaver that was attacking their leader (I wonder if there’s a badge for that). Boy Scouts and infectious diseases are in the news again, but not with as happy a story. In the recent incident reported on ProMED, ten Boy… Continue Reading

Spike in Michigan canine lepto cases

Veterinarians at Michigan State University’s College of Veterinary Medicine are warning of an upswing in leptospirosis in dogs in the Detroit area. More than 20 cases of leptospirosis have been reported in dogs in the Detroit area, and it’s likely that many more unreported cases have occurred.

Leptospirosis vaccination in dogs

Posted in Dogs
Leptospirosis is disease caused by several types of Leptospira bacteria. It’s often called a re-emerging disease in dogs, because the incidence has been increasing over the past couple of decades in many areas. While the overall number of infections is limited, when it does occur lepto can cause serious disease, including kidney failure. It’s also… Continue Reading

Leptospirosis and cold weather

Posted in Dogs
When we have a -30C windchill and snow on the ground, my first thoughts usually aren’t about survival of bacteria in the outdoor environment. However, some microorganisms are well adapted for survival in various adverse conditions and we shouldn’t assume that cold=dead for every bug of concern. Along that line, we received a question recently… Continue Reading

Canine lepto: It’s that time of year again

The latest newsletter from the University of Guelph‘s Animal Health Laboratory contains a brief update on the percentage of positive MAT tests for canine leptospirosis that the lab has seen in the first half of 2009.  Approximately 30% of the tests have been positive, which is up from the previous two years.  However, the prime… Continue Reading

Weil’s disease from a pet rat

A recent edition of the Veterinary Record contains a case report of Weil’s disease in a person that adopted a feral (wild) rat (Strugnell et al, 2009). Weil’s disease is a severe disease of the kidneys, liver and other body systems that can develop after acute leptospirosis (infection by Leptospira bacteria). This group of bacteria… Continue Reading
