An investigation was made into the occurrence of antibodies to Toxoplasma gondii, Leishmania infantum and Neospora caninum in 151 domestic cats, based on the indirect fluorescent antibody test (IFAT). Serum samples were collected from 151 domestic cats (65 free-roaming and 86 domiciled cats; 55 males and 96 females) in Campo Grande, Mato Grosso do Sul, Brazil between January and April 2013. IgG antibodies to T. gondii, L. infantum and N. caninum were found, respectively, in 49 (32.5%), 34 (22.5%) and 10 (6.6%) sampled cats. A positive correlation was found between T. gondii and N. caninum, T. gondii and L. infantum, and N. caninum and L. infantum (p <0.05) infections. Also, a significant interaction was identified between gender and area of activity on the probability of T. gondii (p = 0.0324) infection. However, no significant interaction was observed between gender and area of activity on infections by either N. caninum or L. infantum. This study showed that cats from an area endemic for visceral leishmaniasis in Brazil are exposed to three different protozoans, two of which are causal agents of important zoonosis.
基于间接荧光抗体试验（IFAT），对151只家猫中弓形虫、婴儿利什曼原虫和犬新孢子虫抗体的出现情况进行了调查。2013年1月至4月期间，从巴西南马托格罗索州大坎普市的151只家猫（65只自由放养和86只家养猫；55只雄性和96只雌性）采集了血清样本。在采样的猫中，分别发现49只（32.5%）、34只（22.5%）和10只（6.6%）存在针对弓形虫、婴儿利什曼原虫和犬新孢子虫的IgG抗体。发现弓形虫与犬新孢子虫、弓形虫与婴儿利什曼原虫以及犬新孢子虫与婴儿利什曼原虫感染之间存在正相关（p<0.05）。此外，还确定了性别和活动区域对弓形虫感染概率有显著交互作用（p = 0.0324）。然而，未观察到性别和活动区域对犬新孢子虫或婴儿利什曼原虫感染有显著交互作用。本研究表明，来自巴西内脏利什曼病流行地区的猫接触到三种不同的原生动物，其中两种是重要人畜共患病的病原体。
