Coinfection by Toxoplasma gondii and Leishmania spp. in domestic cats (Felis catus) in State of Mato Grosso do Sul

Introduction Leishmaniasis and toxoplasmosis are important to public health. Methods Antibodies for Toxoplasma gondii and Leishmania spp. were evaluated in cats from Campo Grande, State of Mato Grosso do Sul, Brazil, a region endemic for canine visceral leishmaniasis. Serum samples from 50 asymptomatic cats were titrated for T. gondii by the immunofluorescence antibody test and modified agglutination test and for Leishmania spp. by the immunofluorescence antibody test. Results These two agents coinfected two (4%) of the 50 tested animals. Conclusions These findings demonstrate the concomitant presence of two important zoonoses in cats from Brazilian endemic regions for canine visceral leishmaniasis.

引言 利什曼病（Leishmaniasis）与弓形虫病（toxoplasmosis）均为具有重要公共卫生意义的疾病。
方法 研究对象为巴西南马托格罗索州坎波格兰德市的家猫，该区域为犬内脏利什曼病（canine visceral leishmaniasis）流行区。本研究对50份无症状家猫的血清样本开展检测：采用免疫荧光抗体试验（immunofluorescence antibody test）与改良凝集试验（modified agglutination test）测定刚地弓形虫（Toxoplasma gondii）的抗体滴度，采用免疫荧光抗体试验测定利什曼原虫属（Leishmania spp.）的抗体滴度。
结果 50只受检家猫中，共有2只（占比4%）同时感染这两种病原体。
结论 本研究结果证实，在巴西犬内脏利什曼病流行区域的家猫群体中，同时存在这两种重要的人兽共患病（zoonoses）。
