抄録

We investigated the prevalence of Salmonella enterica and its antimicrobial resistance from 79 green anoles, the invasive alien species inhabits Haha-jima of the Ogasawara archipelago. Samples were collected during the period between 2009 and 2010. The resistance of S. enterica of these samples against 12 common antimicrobial agents was also determined. Salmonella strains, including serovar Oranienburg and Aberdeen, were detected from the large intestines of 30.4% of 79 green anole samples. And 37.5% of which were resistant to Oxytetracycline. This study suggests that green anoles may play an important role of the infection of S. enterica on this island. Attention is needed from the aspect of public and ecological health.
