Toxoplasma gondii and Neospora caninum are widespread cyst-forming coccidian parasites of the subfamily Toxoplasmatinae that infect a wide range of wild and domestic animals. Whereas T. gondii is a zoonotic disease, N. caninum is restricted to nonhuman animals. Some chiropteran species can be infected by T. gondii and present fatal toxoplasmosis. In most cases, T. gondii -infected bats are believed to remain asymptomatic and to act as an infection source to other animals. It is not known whether N. caninum can infect bats. We determined infection rates of T. gondii and N. caninum in free-living bats in the state of Bahia, Brazil. Brain samples from 97 bats of seven species, captured in 2008-15, were analyzed by PCRs for T. gondii and N. caninum . Two of the 97 samples were positive for T. gondii DNA. None of the samples were positive for N. caninum DNA, suggesting that the bats were not susceptible to N. caninum infection or that its prevalence was very low.
刚地弓形虫和犬新孢子虫是弓形虫亚科广泛存在的形成包囊的球虫寄生虫，可感染多种野生动物和家畜。虽然弓形虫病是一种人畜共患病，但犬新孢子虫仅感染非人类动物。一些翼手目物种可被弓形虫感染，并出现致命的弓形虫病。在大多数情况下，感染弓形虫的蝙蝠被认为没有症状，并作为其他动物的感染源。目前尚不清楚犬新孢子虫是否能感染蝙蝠。我们测定了巴西巴伊亚州自由生活蝙蝠中弓形虫和犬新孢子虫的感染率。对2008年至2015年捕获的7个物种的97只蝙蝠的脑样本进行了弓形虫和犬新孢子虫的聚合酶链反应分析。97个样本中有2个弓形虫DNA呈阳性。没有样本的犬新孢子虫DNA呈阳性，这表明蝙蝠对犬新孢子虫感染不敏感，或者其流行率非常低。
