Beach surveys for harp (Phoca groenlaandica) and hooded (Cystophora cristata) seals documented a dramatic increase in their numbers on Sable Island in mid 1990s. In the 1980s, no more than five animals of both species were observed on this island each year, however, during late 1994 to 1998, 1,191 h...

Of 4,268 wild ducks sampled in Canada in 2005, real-time reverse transcriptase-PCR detected influenza A matrix protein (M1) gene sequence in 37% and H5 gene sequence in 5%. Mallards accounted for 61% of samples, 73% of M1-positive ducks, and 90% of H5-positive ducks. Ducks hatched in 2005 accounted ...

Between 1993 and 1999, encephalitis caused by morbillivirus was diagnosed by immunohistochemistry and histology in six lynx (Lynx canadensis) and one bobcat (Lynx rufus) in the eastern Canadian provinces of New Brunswick and Nova Scotia. Five of the six cases in lynx occurred within an 11-mo period ...

Although the Mallard (Anas platyrhynchos) is considered an important maintenance host for low pathogenic avian influenza (LPAI) viruses, viral cell tropism and pathology in naturally infected birds are largely unknown. In August 2006, we collected 19 free-living hatch-year Mallards that were positiv...

This report describes the first 4 years of an experimental rotation in ecosystem health offered to senior veterinary students in Canada. Faculty from the 4 Canadian veterinary colleges collaborated in offering the rotation once annually at one of the colleges. The first rotation was held in Guelph, ...

A stranded juvenile fin whale was successfully euthanized with an intravenous injection of sedative and cardioplegic drugs. Veterinarians may face a number of serious difficulties if called to perform this task, and advance preparation is required for successful euthanasia of these animals.

We describe 4 years of an experimental rotation in ecosystem health offered to senior veterinary students in Canada. Faculty from the 4 Canadian veterinary colleges collaborated in offering the rotation once annually at 1 of the colleges. The 1st rotation was held in Guelph in 1993, followed in succ...

Over the last several decades, elders and hunters of the Innu Nation in Labrador, Canada, have expressed concerns over perceived declines in environmental health and the integrity of country food, including caribou. The primary objective of this study was to determine links between specific health p...

In 2005, trichomonosis emerged as a new cause of substantial mortality in United Kingdom (UK) greenfinch (Carduelis chloris) and chaffinch (Fringella coelebs) populations. Similar to the UK, in the summer and fall of 2007–2009 and 2011, mortalities due to trichomonosis occurred in the Canadian Mar...
