Abstract

One hundred and thirty-nine reptiles consisting of 99 tortoises, 32 lizards and 8 snakes sold at pet stores in Yamaguchi prefecture were examined for the prevalence of Salmonella spp. A total of 50.4% samples were positive for isolation of Salmonella spp., and the isolation frequencies were 42% in tortoises, 69% in lizards and 75% in snakes, respectively. The 82 strains collected from 70 positive samples were classified into four Salmonella subspecies (enterica [subsp. I], salamae [II], diarizonae [IIIb] and houtenae [IV]) and 53 serotypes. The 59 strains in subsp. I were typed to 38 serotypes. Serovars Abony, Pomona and Thompson were dominant in tortoises, and serovars Fluntern and Kentucky were dominant in lizards. The antimicrobial susceptibility with 12 drugs were examined for the 82 isolates with the result that 50% (41 isolates) were resistant to one or more drugs. Among the resistant isolates, one strain showed multiple resistances to the eight drugs examined. Two strains obtained from two different lizards exhibited resistance against new quinolones antibiotics such as CPFX and TFLX.
