Prevalence of antibodies to Toxoplasm gondii was studied using the latex agglutination (LA) method, followed by sucrose density gradient centrifugation (SDGC) method on the small Indian mongoose (Herpestes auropunctatus), which inhabits Amami-Oshima Island. Of the 362 samples, 38 (10.5%) revealed positive. Single or double peaks in the 7–8 and/or 12–14 fraction to LA titer by SDGC indicated the early stage of T. gondii infection. It is suggested that domestic/feral cats play an important role for spreading this zoonotic pathogen to the mongoose as well as other species that are endemic to this island. Future studies are warranted to prevent the transmission of T. gondii among cats and wild animals in order to maintain the ecosystem health.

Here, we investigated the prevalence of Salmonellaenterica, with and without resistance to 17 common antimicrobial agents, in 706 green anoles (Anolis carolinensis) that were collected in Naha and Tomishiro Cities, Okinawa Main Island, Japan, between 2009 and 2014. Salmonella strains, including S. enterica Weltevreden and Enteritidis serovars, were identified in the large intestinal content samples extracted from 15 (2.1%) of the analyzed green anoles. No antimicrobial resistance was detected. Thus, the present study demonstrates that although the prevalence of Salmonella and the risk of its transmission from the green anoles to humans or other animals on Okinawa Main Island are relatively low, the green anole population nevertheless represents a potential source of Salmonella infection that could affect human health in this region.

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.
