Production of enterotoxin by Yersinia enterocolitica.
Forty-three strains of Yersinia enterocolitica isolated from children with gastroenteritis and 18 laboratory strains were examined for enterotoxin production by using the infant mouse, Y1 adrenal cell, and rabbit ileal loop assay systems. All clinical isolates and seven laboratory strains were found enterotoxigenic in the infant mouse model, but none of the strains produced toxin in the Y1 adre...
متن کاملRelationship of virulence-associated autoagglutination to hemagglutinin production in Yersinia enterocolitica and Yersinia enterocolitica-like bacteria.
A total of 339 Yersinia strains were tested for virulence-associated autoagglutination and hemagglutinin (HA) production. Autoagglutination was frequent among human clinical isolates belonging to Y. enterocolitica serogroups O:3, O:8, and O:9 and among porcine isolates of serogroups O:3 and O:9. Positive autoagglutination results were also observed in serogroups O:1 and O:2, associated with out...
متن کاملEnterotoxin production and thermal resistance of Yersinia enterocolitica in milk.
Three of 36 raw milk isolates of Yersinia enterocolitica produced enterotoxin in milk at 25 degrees C, but not at 4 degrees C. No strain tested could survive pasteurization.
متن کاملPrevalence of Yersinia enterocolitica across phases of swine production
The objective of this study was to describe the prevalence of Yersinia enterocolitica (YE) in different swine production phases. In this cross-sectional study, individual pigs on eight farrowto-finish farms were sampled for YE by collection of both feces and oral-pharyngeal swabs. Samples were cultured with a three-week cold enrichment followed by culture onto selective media. Presumptive YE is...
متن کاملRuminal Protein Degradation and Estimation of Rumen Microbial Protein Production
Animal agricultural production systems are major sources of nonpoint pollution affecting quality of water sources. Nitrogen has been identified as the foremost source of nonpoint water pollution and the potential negative impacts of N have become an area of public concern. protein degradation from feed ingredients is an important factorinfluencing AA supply to the duodenum. Ruminal proteolysis...
