Parasitic and Infectious Diseases
Currently, we are surveying parasitic and infectious diseases in wolves and their close relatives, dogs. As industrial activity such as logging increases in coastal B.C., natural disease cycles may be disrupted and/or new pathogens introduced that could threaten the health of wolves, other wildlife, domestic animals, and humans.
Analysis of scats for evidence of parasites, combined with molecular genetic techniques, is generating information that we are using to develop a spatially-explicit model of parasite distribution in dogs and wolves across the coastal landscape. Blood samples taken from dogs – which serve as ‘sentinels of disease’ in wolves – tell us about infectious diseases to which coastal canids have been exposed. Ultimately, this information will provide baseline knowledge for monitoring existing and potential disease threats.
Notes from the Lab
By Heather Bryan Biologist Rainforest Wolf Project Parasitology lab University of Saskatchewan, Saskatoon March 2008 Peering down the eyepiece of my microscope, I scan a slide for larval stages of parasites. I find one that is familiar-a brown, translucent egg of the tapeworm Diphyllobothrium-and begin to count. One, two ….
By Heather Bryan, PhD Candidate and Rainforest Wolf Project From the white sands of Koeye River September 2007 Twilight at Koeye River flushes white sand dunes pink, softens the sound of howling wind in Fischer channel, and dampens the roar of the wave standing at river’s mouth. In these short moments of calm, a big […]
