摘要: In the summer of 1999, incidence Salmonella enterica serotype Infantis infections in Alberta rose dramatically. Subsequent laboratory and epidemiological investigations established that an outbreak human disease caused by this organism was occurring across Canada associated with pet treats for dogs produced from processed pig ears. Laboratory using phage typing pulsed-field gel electrophoresis (PFGE) isolates ear humans exposed to comprised a well-defined subset all analyzed. Of 53 subtypes obtained around time as defined PFGE typing, only 6 were both infection isolation Together information studies, these cause outbreak. The results are consistent model which contaminated constitute long-term, continuing vehicle population rather than causing temporally delimited point-source outbreaks. During course outbreak, several other serotypes also isolated treats, suggesting products may be important source enteric dogs. Though subjected no link could definitively established, contribution remains unclear. Elimination bacterial contamination is required reduce risk products.
