Research project on bovine anaplasmosis
Project Goals
i. Determine the occurrence of anaplasmosis within beef cattle herds in western Canada.
ii. Survey herd management practices that may affect the risk of anaplasmosis.
iii. Develop a chute-side test that can detect infected cattle quickly.
What we will do
i. Test beef cattle herds, ticks and flies for Anaplasma.
ii. Conduct an online survey to document current cattle husbandry practices.
iii. Use cattle blood to develop a test that detects Anaplasma marginale, but not bacteria that
don’t cause anaplasmosis
Project Outcomes
i. Current representation of risk factors for bovine anaplasmosis, including where anaplasmosis occurs & animal management practices
ii. Quick and simple diagnostic tool to detect animals infected with A. marginale
iii. Development of practical and appropriate methods for preventing the introduction and spread of anaplasmosis in beef cattle herds.
iv. Quick and effective response to infections for improved animal health and welfare.

Foreign Animal Disease Preparedness and Prevention for Cattle
Dr. Karin Orsel, a professor in epidemiology and infectious diseases from the University of Calgary, has some up close and personal experience with the impacts of bovine infectious diseases of cattle that currently don’t exist in Canada.
These foreign animal diseases, such as foot and mouth disease, are kept out of Canada only by the strength of our farm biosecurity and through the ongoing monitoring and reporting of any of signs of concern to veterinarians for further investigation. Her experiences highlight the importance of vigilance and traceability in the cattle sector to ensure the health of our cattle and the security of our food systems.
Update: Beef cow-calf vaccine project overview
Dr. Joyce Van Donkersgoed, a beef veterinarian and epidemiologist, shares recent results from producer and veterinarian surveys regarding beef cattle vaccination. She also provides a number of beef health vaccination planning resources and decision-making tools developed by a research team of cattle experts to support the valid veterinary-client-patient relationship.
Zoonotic diseases of cattle
Dr. Sylvia Checkley, veterinarian, epidemiologist and associate professor in ecosystem and public health at the University of Calgary, discusses the diseases of cattle that can be transmitted to people (zoonotic diseases). These should be on the radar for anyone working regularly with cattle or calves - producers and veterinarians alike.
Hepatic necrosis in beef calves Spring 2022

A short summary of the investigations to date follows.
Severe Foot Lameness in Weaned Calves, Winter 2023
In early 2023 two lots of weaned calves (one over-wintered bulls, one assembled feeder steers) were identified experiencing severe foot lameness, with common features of coronary band vasculitis and hoof wall separation. A short summary of the investigation to date follows:
