| foodborne gastroenteritis due to norwalk virus in a winnipeg hotel. | within 1 week four separate incidents of gastroenteritis presumed to be foodborne were reported by guests of a winnipeg hotel. investigation revealed poor food-handling practices and illness among the kitchen staff. elevated bacterial counts and escherichia coli were found in 15 of 24 samples of food tested, and staphylococcus aureus was isolated from 2 pastry samples. culture of 14 stool samples for bacteria yielded clostridium perfringens in 1 sample from a staff member and coagulase-positive ... | 1989 | 2541881 |
| epizootic necrotic enteritis in wild geese. | outbreaks of a disease characterized by severe necrotic enteritis occurred among canada geese (branta canadensis), lesser snow geese (anser caerulescens), ross' geese (a. rossi), and white-fronted geese (a. albifrons) on lakes in saskatchewan and manitoba during the autumn of 1983, 1984 and 1985. ducks using the lakes were apparently not affected. lesions in the geese closely resembled those described in enteritides in other species associated with the proliferation of clostridium perfringens in ... | 1987 | 3625893 |
| production of class a biosolids with anoxic low dose alkaline treatment and odor management. | the feasibility of full-scale anoxic disinfection of dewatered and digested sludge from winnipeg, manitoba with low lime doses and lagoon fly ash was investigated to determine if a class a product could be produced. lime doses of 50 g, 100 g, and 200 g per kg of biosolids (dry) were used along with fly ash doses of 500 g, 1,000 g, and 1,500 g per kg of biosolids (dry). the mixed product was buried in eight-10 cubic metre trenches at the west end water pollution control center in winnipeg. the tr ... | 2004 | 15259947 |
| toxinotyping of necrotic enteritis-producing and commensal isolates of clostridium perfringens from chickens fed organic diets. | the present study determined the effect of clostridium perfringens isolates taken from necrotic enteritis (ne) outbreaks on organic farms in a ne virulence testing model. thirteen strains were isolated in the course of the study. six c. perfringens field isolates were taken from a naturally occurring ne outbreak on an organic farm. polymerase chain reaction toxinotyping was used to establish c. perfringens strains, as well as to create a toxin profile. all field isolates were found to be type a ... | 2010 | 21154057 |
