| human and animal epidemic of yersinia enterocolitica o:9, 1989-1997, auvergne, france. | yersinia enterocolitica o:9 infections were reported in auvergne in 1988 to 1989, while brucellosis due to brucella abortus was almost eliminated. the serologic cross-reactions between the two bacteria complicated the diagnosis of brucellosis cases. in 1996, human cases of yersinia enterocolitica o:9 infection were detected, with a peak incidence of 12 cases. veterinary surveillance could have predicted the emergence of this disease in humans. | 1999 | 10511531 |
| prevalence and characterization of shiga toxin-producing escherichia coli isolated from cattle, food, and children during a one-year prospective study in france. | during a 1-year survey of shiga toxin-producing escherichia coli (stec) prevalence in central france, 2,143 samples were investigated by pcr for shiga toxin-encoding genes. a total of 330 (70%) of 471 fecal samples collected from healthy cattle at the clermont-ferrand slaughterhouse, 47 (11%) of 411 beef samples, 60 (10%) of 603 cheese samples, and 19 (3%) of 658 stool specimens from hospitalized children with and without diarrhea were positive for the stx gene(s). a stec strain was isolated fro ... | 2000 | 10698990 |
| prevalence of cryptosporidium infection in calves in france. | two multicentre surveys were conducted in france to estimate the prevalence of cryptosporidium infection in calves using qualitative elisa for detection of cryptosporidium coproantigens and oocysts. the first survey involved 4-12-day-old calves in six dairy-calf distribution centres, collecting calves from seven administrative regions (aquitaine, bretagne, franche-comté, lorraine, normandie, nord, pays de loire). for each region, 20 calves were selected every month for 12 consecutive months (oct ... | 2000 | 10729640 |
| tanker milk variability according to farm feeding practices: vitamins a and e, carotenoids, color, and terpenoids. | the aim of this work was to study the variability in the composition of bulk milk mixtures of fat-soluble compounds (vitamins a and e, carotenoids, and terpenoids) and assess the links with milk production conditions. milk from 10 collection trips in the french department of the haute-loire (10 to 36 herds per trip) was sampled in the tanker twice during the winter period and 3 times during the grazing season. the collection trips differed in their altitude (440 to 1,150 m) and the forage system ... | 2007 | 17881712 |
