One common vector of transmission for tularemia is a tick.

Tularemia, a potentially serious and life-threatening disease

Vet Advice with Dr. Ron Clarke

Tularemia, sometimes called rabbit fever, is an uncommon but debilitating disease spread from animals to man caused by the bacteria Francicella tularensis. It can be found in a variety of animal hosts, notably lagomorphs (rabbits and hares), aquatic rodents (muskrats, beavers, and water voles), other rodents (water and wood rats and mice), squirrels, and cats.

Hot weather and a stagnant water supply create prime conditions for cyanobacteria to form.

Hot weather increases livestock-poisoning risk

Several advisories were posted in 
North Dakota this month

High temperatures promote the growth of blue-green algae, which can produce harmful toxins. Cyanobacteria, also known as blue-green algae, can produce toxins that are harmful to livestock, wildlife and people. This month North Dakota Department of Health has posted blue-green algae advisories for four lakes. In addition, several water samples associated with the death of […] Read more


Lapses in biosecurity create long-standing risks

Reducing risk of transmission of salmonella and other diseases

Salmonella bacteria have been isolated from nearly all vertebrates, and infections have been associated with both animal and human disease. Not uncommonly, foods of animal origin have been implicated as the source of human illness caused by salmonella. Typical signs of salmonella infection in cattle and humans include fever and diarrhea. Severe cases can result […] Read more

The search continues for TB and JD vaccines

Animal Health: Treatment for the elusive diseases grows closer

We could be lucky and find our vaccine candidates for bovine tuberculosis and Johne’s disease within a month, or it could take a year and a half. We hope within a two-year window we will have candidates ready to test out in the field.” These encouraging words come from Dr. Andrew Potter, CEO at the […] Read more


Keep Q fever in mind this calving season

Vet Advice with Dr. Ron Clarke

Q fever is a potential zoonosis every stock person should keep in mind through calving, lambing and kidding season. The disease, Q fever, and the organism, Coxiella burnetii, when present represent a serious threat to human health. Every gram of afterbirth or fluid from an infected animal contains millions of infectious particles and only a […] Read more

Non-O157 Shiga toxigenic E. coli (STEC)

Research on the Record with Reynold Bergen

There are between 50,000 and 100,000 different serotypes (strains) of E. coli. Most are harmless, some may be beneficial, but some produce a very dangerous Shiga toxin. Shiga toxigenic E. coli (STEC) can cause vomiting, diarrhea and abdominal pain in people. E. coli O157:H7 is the most well-known STEC, but it is not the only […] Read more


Bovine TB probe turns up more TB-positive cattle

Federal inspectors have confirmed a southeastern Alberta cow found with bovine tuberculosis in September was not just a one-off. The Canadian Food Inspection Agency on Friday reported five more cattle from the initial cow’s index herd in southeastern Alberta are confirmed to have been infected with Mycobacterium tuberculosis bacteria — presumed to be to be […] Read more

Anaplasmosis is the most common tick-transmitted disease of cattle worldwide.

Did we walk away from anaplasmosis too soon?

Vet Advice with Dr. Ron Clarke

As of April 1, 2014, anaplasmosis in cattle was removed from the list of federally reportable diseases. The federal government is no longer involved in controlling the disease. Import controls were basically removed. Cows purchased from infected areas of North America are no longer tested before entering Canada despite the fact that testing reduces the […] Read more


Flies may not be the only way pinkeye is being spread in herds, according to this Alberta project, which has management implications.

Potential new causes of pinkeye uncovered

Findings from a recent Alberta project have implications for management practices that could help prevent the spread of pinkeye (infectious bovine keratoconjunctivitis, IBK) within a herd. Relatively little attention has been given to pinning down the cause and prevention of pinkeye even though it is the most common eye disease of cattle worldwide, and highly […] Read more

Pneumonia: the disease that won’t go away

The three categories of pneumonia and how to tell them apart

Environment, germs and immunity are top of mind when thinking of all the risk factors that could set the stage for pneumonia in cattle. The forgotten factor is one beyond producers’ control and the reason why pneumonia will always be a problem — anatomy. Bovine lungs are very small relative to the animal’s oxygen requirements, […] Read more
