The species of the genus Leishmania are protozoa that are widely distributed from Asia to the Americas, affecting humans and wild and domestic animals. Little is known about infection by Leishmania in bats in the state of Maranhão, Brazil. The objective of this study was to investigate the presence of Leishmania in bats in Maranhão. Blood samples were collected from bat species for parasitological diagnosis. Samples of spleen and liver were collected for molecular analysis. All the blood cultures were negative. In two blood smears, organisms similar to amastigotes of Leishmania sp. were detected. Of the 116 samples, two spleen samples were positive and showed similarity to Leishmania infantum. Therefore, further studies are needed to elucidate whether bats take part in the epidemiological chain of leishmaniasis.
利什曼原虫属的物种是广泛分布于亚洲到美洲的原生动物，影响人类和野生及家养动物。关于巴西马拉尼昂州蝙蝠感染利什曼原虫的情况知之甚少。本研究的目的是调查马拉尼昂州蝙蝠中利什曼原虫的存在情况。从蝙蝠物种采集血液样本进行寄生虫学诊断。采集脾脏和肝脏样本进行分子分析。所有的血液培养均为阴性。在两张血涂片上，发现了类似于利什曼原虫的无鞭毛体。在 116 个样本中，有两个脾脏样本呈阳性，与利什曼原虫婴儿亚种相似。因此，需要进一步的研究来阐明蝙蝠是否参与了利什曼病的流行病学链。
