Hepatitis B virus (HBV) chronically infects approximately 250,000 Canadians and 350 million people worldwide. Without intervention, approximately 15% to 40% of chronically infected individuals will eventually develop cirrhosis, end-stage liver disease or hepatocellular carcinoma, or require liver transplantation. The availability and extensive use of the(More)
Human metapneumovirus (hMPV), a newly discovered paramyxovirus, has been associated with acute respiratory tract infections (ARIs) ranging from upper ARIs to severe bronchiolitis and pneumonia. Important questions remain on the contribution of hMPV to ARIs and its impact on public health. During the 2001-2002 season, we conducted a collaborative study with(More)
We investigated the effect of Eleutherococcus senticosus Maxim L (ESML) on performance during submaximal and maximal aerobic exercise. Twenty highly trained distance runners randomly assigned in matched pairs to either an experimental (ESML) or placebo (PL) group, participated in an 8-wk double-blind study during which they completed five trails of a 10-min(More)
The Salmonella status of 15 different farm flocks was assessed at the farm level and at processing plants. Bacteriological examination for Salmonella was made of litter, dust, feed, 5-day-old culled chicks, and chicken carcasses. Fresh straw litter was found contaminated with Salmonella and may be a source of flock infection. Culture of floor litter can be(More)
The British Columbia Center for Disease Control laboratory performs approximately 95% of all hepatitis C virus (HCV) antibody tests for the province's 4 million inhabitants. In 2002, the laboratory tested 96,000 specimens for anti-HCV antibodies, of which 4,800 (5%) were seroreactive and required confirmation of active infection. Although HCV RNA assays(More)
BACKGROUND In summer 2003, a respiratory outbreak was investigated in British Columbia, during which nucleic acid tests and serology unexpectedly indicated reactivity for severe acute respiratory syndrome coronavirus (SARS-CoV). METHODS Cases at a care facility were epidemiologically characterized and sequentially investigated for conventional agents of(More)
Salmonella contamination is a major problem in the poultry industry, but no data are available on the prevalence in geese. From two slaughter facilities in Manitoba, 130 carcass rinsings and 315 cloacal swabs from a total of 17 flocks of domestic geese were examined for salmonellae. Sixty percent of the carcass rinsings and 18.4% of the cloacal swabs were(More)
