Little is known about toxoplasmosis in animals of the Fernando de Noronha Island, Brazil. Therefore, we investigated the prevalence of Toxoplasma gondii infection in the total population of pet cats (n=348), dogs (n=320), pigs (n=27), equines (n=101), as well as a significant portion of the population of feral cats (n=247) of the Island by Indirect Fluorescent Antibody Test. Anti-T. gondii IgG antibodies were found in 71.26%, 54.74%, 48.75%, 51.85% and 22.7%, of the pet and feral cats, dogs, pigs and equines, respectively, demonstrating a high prevalence of T. gondii infection in the wild and domestic animals of the Island. The Kernel intensity estimator showed a correlation between areas with high prevalence of infection in cats and occurrence of infection in the other studied species. We suggest that the island's health authorities should develop initiatives to reduce the population of cats and alert the island's population about the risk of T. gondii infection.
关于巴西费尔南多·迪诺罗尼亚岛动物的弓形虫病，人们了解甚少。因此，我们通过间接荧光抗体试验，对该岛宠物猫（n = 348）、狗（n = 320）、猪（n = 27）、马（n = 101）以及相当一部分野生猫（n = 247）的总体弓形虫感染率进行了调查。在宠物猫和野猫、狗、猪及马中，分别有71.26%、54.74%、48.75%、51.85%和22.7%检测到抗弓形虫IgG抗体，这表明该岛的野生动物和家畜中弓形虫感染率很高。核强度估计器显示，猫感染率高的区域与其他研究物种的感染发生率之间存在相关性。我们建议该岛的卫生当局应采取措施减少猫的数量，并提醒岛上居民注意弓形虫感染的风险。
