In the summer of 1999, the incidence of Salmonella enterica serotype Infantis infections in Alberta rose dramatically. Subsequent laboratory and epidemiological investigations established that an outbreak of human disease caused by this organism was occurring across Canada and was associated with pet treats for dogs produced from processed pig ears.(More)
Co-cultivation of Legionella pneumophila serogroup I and Acanthamoeba palestinensis in Neff's medium at 35 degrees C resulted in the intracellular multiplication of the bacteria as demonstrated by electron microscopy and immunofluorescence. In the closed experimental system used, the number of legionellae rose from 10(7) colony forming units (c.f.u.)/ml(More)
In an anonymous survey, 433 sera from Canadian individuals of selected categories were tested for the presence of antibody to hepatitis C virus (HCV) using a recombinant antigen-based immunoassay. About 50% of intravenous drug abusers (IVDA), 10% of transfusion recipients and an overall average of 7.9% of male homosexuals were reactive for antibody to HCV.(More)
To assess the prevalence and pathological role of hepatitis D virus (HDV) infection in western Canada, we tested a total of 310 sera from the province of Alberta, Yukon and Northwest Territories for antibody to HD (anti-HDV) by commercial solid phase radioimmunoassay. Two hundred and forty-five sera were hepatitis B surface antigen (HBsAg) positive. These(More)
In many developing countries sheep and horse blood, the recommended blood supplements in bacteriological media, are not readily available, whereas pig and goat blood are. Therefore, this study examined the use of pig and goat blood as potential substitutes for sheep blood in blood-supplemented bacteriologic media commonly used in clinical microbiology(More)
In a prospective survey of 773 healthy schoolchildren in southern Alberta, Canada, Neisseria polysaccharea was isolated from the pharynxes of only 4 (0.5%) subjects, whereas Neisseria lactamica and Neisseria meningitidis were isolated from 110 (14%) and 15 (2%) children, respectively. These strains of N. polysaccharea, together with three other sporadic(More)
Implication of the beta-hemolytic non-group A streptococci (BHNAS) as pharyngeal pathogens has been based predominantly on reports of a few outbreaks, small case clusters, and anecdotes. These organisms have long been noted to constitute a significant number of the beta-hemolytic streptococcal isolates from throats of symptomatic and asymptomatic patients(More)
A questionnaire survey concerning Streptococcal pharyngitis was completed by 85 southern Alberta family physicians. The data revealed a significant trend to overtreat pharyngitis with antibiotics because of the unreliability of clinical diagnosis and the lack of diagnostic manoeuvres with suitable ability to influence management. These data and a further(More)
