infection can pose serious health issues, especially to children, elders or immunosuppressed humans. Wild populations of reptiles can reach prevalence of up to 100% and the direct or indirect transmission from reptiles to humans have been extensively reported. Fernando de Noronha (FN) is an inhabited oceanic archipelago in the northeast coast of Brazil, with an economy based on tourism. The tegu () is the largest lizard native to South America and was introduced to the archipelago in the early 20th century. This study determines the prevalence, serotypes, antimicrobial resistance, and molecular epidemiology of in the tegu population from FN archipelago. Results show that is widely distributed in the FN tegu population, with 43.8% prevalence. The bacteria were isolated from 70.5% of the sampled sites and a total of 15 serotypes were detected in 98 isolates. Strains were further classified into 31 genotypes. Recaptured animals presented distinct genotypes in each season, demonstrating a seasonal strain turnover. Most isolates from FN tegus presented low antimicrobial resistance. This is possibly due to geographical isolation of the island population, hampering contact with strains from livestock from the continent, where antimicrobial resistance is common.
感染会引发严重的健康问题，尤其是对儿童、老年人或免疫功能低下的人。野生爬行动物种群的感染率可达100%，并且从爬行动物到人类的直接或间接传播已有广泛报道。费尔南多·迪诺罗尼亚（FN）是巴西东北海岸一个有人居住的海洋群岛，其经济以旅游业为基础。鬃狮蜥是南美洲本土最大的蜥蜴，于20世纪初被引入该群岛。本研究确定了FN群岛鬃狮蜥种群中[细菌名称未给出]的流行率、血清型、抗菌药物耐药性和分子流行病学。结果表明，[细菌名称未给出]在FN鬃狮蜥种群中广泛分布，流行率为43.8%。从70.5%的采样地点分离出了该细菌，在98株分离株中总共检测到15种血清型。菌株进一步分为31种基因型。重新捕获的动物在每个季节呈现出不同的基因型，表明存在季节性菌株更替。来自FN鬃狮蜥的大多数[细菌名称未给出]分离株表现出低抗菌药物耐药性。这可能是由于该岛屿种群的地理隔离，阻碍了与来自大陆家畜的菌株接触，而在大陆抗菌药物耐药性很常见。
