摘要: Salmonella enterica serovar Typhimurium was isolated from the intestinal contents of Rattus rattus and norvegicus house rats captured at two buildings, designated buildings J YS, in Yokohama City, Japan. From October 1997 to September 1998, 52 339 (15.3%) were found carry definitive phage type 104 (DT104). In building J, 26 161 (16.1%) carried DT104 over 1-year study period, compared 178 (14.6%) YS. The isolation rates R. similar buildings. Most strains (24 26) showed resistance ampicillin, chloramphenicol, streptomycin, sulfisoxazole, tetracycline contained both 1.0- 1.2-kbp integrons, carrying genes pse1, pasppflo-like, aadA2, sulI, tet(G). All YS resistant ampicillin had integron pse1 sulI. Cluster analysis pulsed-field gel electrophoresis patterns BlnI-digested DNAs that 22 24 could be grouped into separate clusters each specific for origin. These results indicated prevalent rat colonies suggest may play an important role epidemiology DT104.
