Prevalence and antimicrobial-resistance profiles of Salmonella spp. isolated from green anoles (Anolis carolinensis) collected on the Haha-jima of the Ogasawara archipelago, Japan

A study on Haha-jima, part of Japan's Ogasawara Islands, reveals that 30.4% of green anoles (Anolis carolinensis), an invasive species, tested positive for Salmonella enterica in their large intestines. Notably, 37.5% of these Salmonella strains exhibited resistance to oxytetracycline, a commonly used antimicrobial agent. This suggests that green anoles may contribute to the transmission of Salmonella on the island, posing potential risks to both public and ecological health. The research analyzed samples collected between 2009 and 2010, assessing resistance against 12 antimicrobial agents.
