The seroprevalence of infection by Toxoplasma gondii, Neospora caninum, and Leishmania spp. was detected through an indirect immunofluorescence in 70 cats from the Andradina Municipality, São Paulo State, Brazil. Anti-T. gondii antibodies (titer >64) were detected in 15.7% (11/70) of animals, whereas positivity for N. caninum (titer 16) was not observed in any animal. Of the cats from urban and rural areas, 10.4% (5/48) and 27.2% (6/22) were positive for T. gondii, respectively. Breed, age, food, and contact with animals of other species were significant for considering the positivity for T. gondii (P ≤ 0.0001). Cats having access to streets (17.1%, 11/64), cats cohabiting with rats (19.6%, 10/51), and cats feeding on homemade food and raw milk (27.2%, 6/22) were positive for T. gondii. In addition, 4.2% (3/70) of the cats were positive for Leishmania spp. by ELISA technique and negative by IFAT without coinfection with T. gondii and Leishmania spp. There was no serological positivity against feline immunodeficiency virus or feline leukemia virus. In conclusion, T. gondii infection in part of the feline population from Andradina is not linked to immunosuppressions or coinfections but probably to postnatal infection in association with the type of diet and presence of rats.
巴西圣保罗州安德拉迪纳市的 70 只猫通过间接免疫荧光法检测了弓形虫、刚地弓形虫和利什曼原虫属的感染血清阳性率。15.7%（11/70）的动物检测到抗弓形虫抗体（滴度>64），而任何动物均未检测到刚地弓形虫阳性。来自城市和农村地区的猫中，分别有 10.4%（5/48）和 27.2%（6/22）的猫对弓形虫呈阳性。品种、年龄、食物和与其他物种的动物接触对考虑弓形虫的阳性率有显著影响（P ≤ 0.0001）。有机会接触街道的猫（17.1%，11/64）、与老鼠共同生活的猫（19.6%，10/51）和食用自制食物和生牛奶的猫（27.2%，6/22）对弓形虫呈阳性。此外，通过 ELISA 技术检测到 4.2%（3/70）的猫对利什曼原虫属呈阳性，通过 IFAT 检测呈阴性，且未与弓形虫和利什曼原虫属合并感染。没有猫免疫缺陷病毒或猫白血病病毒的血清学阳性。总之，安德拉迪纳部分猫群的弓形虫感染与免疫抑制或合并感染无关，但可能与饮食类型和老鼠存在有关的产后感染有关。
