Preventing an outbreak: H5N1 in dairy cattle with Dr. Murray Gillies and Dr. Henry Ceelen. Animal Health Insights miniseries, Ep 1, February 13, 2025
Highly pathogenic avian influenza (HPAI) is a contagious viral disease that continues to impact domestic and wild birds. In March of 2024, HPAI was detected in dairy cattle in Texas, and has since spread rapidly across the United States. To date, it has not been detected in Canada in cattle.
In this new miniseries, Dr. Murray Gillies, a veterinarian and the Interim Division Director for the Canadian Animal Health Surveillance System, and Dr. Henry Ceelen, a bovine veterinarian and Secretary Treasurer for the Canadian Association of Bovine Veterinarians, join Dr. Steven Roche of ACER Consulting to discuss HPAI in dairy cattle, including disease presentation, spread, and prevention, as well as the Canadian response.

Les vilains moustiques sous surveillance avec Dre Antoinette Ludwig et Marc Avramov. Perspectives en santé animale, Ep. 24b, 11 Jun 2024
Les moustiques - si vous vivez au Canada, vous devez faire face à ces insectes nuisibles pendant une grande partie du printemps et de l'été. Avec le réchauffement climatique, il est probable que nous verrons apparaître quelques nouvelles variétés de cet insecte irritant dans l'espace aérien canadien, et malheureusement, la variété des espèces signifie également que nous devons faire face à de nouvelles maladies à transmission vectorielle.
Les moustiques sont porteurs et contribuent à la propagation d'une variété de conditions infectieuses à une variété d'espèces - il est donc important pour la santé publique et la santé animale de garder "l’œil dans le ciel" et de surveiller leurs mouvements, leur propagation et leurs préférences en matière d'habitat.
Heureusement, le Canada dispose d'un groupe de chercheurs qui surveillent et d'étudient ce phénomène. Dre Antoinette Ludwig, vétérinaire et épidémiologiste au Laboratoire national de microbiologie de l'Agence de la santé publique du Canada, et Marc Avramov, candidat au doctorat à l'Université Carlton, étudient les maladies transmises par les moustiques et le risque qu'elles représentent pour les populations humaines et animales, ainsi que l'impact du changement climatique sur ces maladies.

Monitoring malicious mosquitoes with Dr. Antoinette Ludwig and Marc Avramov. Animal Health Insights, Ep. 24a, June 11, 2024
Mosquitoes – if you live in Canada, you deal with these pesky bugs for a significant portion of the spring and summer. With warming global temperatures, it is likely that we will see a few new varieties of this irritating insect appear in the Canadian airspace, and unfortunately, this also means we have some new vector-borne diseases to deal with.
Mosquitoes carry and help to spread a variety of infectious conditions to a variety of species – so keeping an “eye on the sky” and monitoring their movement, spread, and habitat preferences is important to public health and animal health.
Luckily, Canada has a group of researchers that are working to monitor and study this very thing. Dr. Antoinette Ludwig, a veterinarian and epidemiologist with the National Microbiology Laboratory at the Public Health Agency of Canada, and Carleton University PhD candidate Marc Avramov, both study the diseases transmitted by mosquitoes and the risk they pose for both human and animal populations, as well as the impact of climate change on these disease patterns.
