The Ontario Animal Health Network had a very productive spring, with many of our networks publishing new species-specific reports. At the end of April, we held our OAHN Annual General Meeting (AGM), with our networks presenting their accomplishments over the past year and plans for the year ahead.
OAHN AGM Speaker Series 2026
For the past two years, we have hosted an OAHN speaker series in place of an AGM keynote; the presentations are available to veterinarians and animal health professionals. Additionally, we post these talks online for all of our registered veterinarians and members. This year, we were fortunate enough to have five talks, which are listed below. A heartfelt thanks to the veterinary experts who provided these talks, and to all of the Ontario veterinary professionals who attended. These talks are password protected on the OAHN website, so you need to register and be signed in to view them.

OAHN Bovine Project: Investigation of Mycoplasma wenyonii and Candidatus Mycoplamsma haemobos in Ontario dairy cattle
The recently completed OAHN bovine network project was a pilot study of blood samples collected from Ontario dairy cattle to determine whether M. wenyonii and C. M. haemobos are present in Ontario dairy herds, and to explore potential herd-level risk factors. In addition to the project report, the network also created a summary document: Tips for Testing Cattle for Mycoplasma wenyonii and Candidatus Mycoplasma haemobos. Both of these documents can be accessed here: Project Report: Investigation of Mycoplasma wenyonii and Candidatus Mycoplamsma haemobos in Ontario dairy cattle [2]
