The aim of this study was to determine the frequency of infection by T. gondii in cats, by examining serum and fecal samples from animals attended at veterinary clinics in the Metropolitan Region of Lima, Peru. We collected and analyzed 154 cat serum samples and 50 fecal samples, regardless of the age, gender or breed. In parallel with the sample collections, the owners answered an epidemiological questionnaire that investigated the following variables: age group, gender, lifestyle (confined, semi-confined or free-living animals), feeding and hunting habits. The serum and fecal samples were analyzed using indirect hemagglutination (IHA) and coproparasitological tests, respectively. IHA showed that the frequency of cat exposure to T. gondii was 11%. Age and gender showed no association with exposure to the parasite. Exposure among the cats was associated with hunting (x2 = 4.98, p = 0.016) and feeding habits (x2 = 13.34, p = 0.001): those fed with raw meat were more exposed than those fed with commercial cat food (x2 = 9.50, p = 0.004) or with homemade food (x2 = 4.1, p = 0.027). The frequency of cats diagnosed in the chronic phase of T. gondii infection was 88% (15/17). No T. gondii oocysts were found in any of the 50 fecal samples examined.
本研究的目的是通过检测秘鲁利马大都市区兽医诊所就诊动物的血清和粪便样本，确定猫感染刚地弓形虫的频率。我们收集并分析了154份猫血清样本和50份粪便样本，不考虑动物的年龄、性别或品种。在采集样本的同时，主人回答了一份流行病学调查问卷，该问卷调查了以下变量：年龄组、性别、生活方式（圈养、半圈养或自由生活的动物）、喂养和捕猎习惯。血清和粪便样本分别采用间接血凝试验（IHA）和粪便寄生虫学检测进行分析。IHA显示猫接触刚地弓形虫的频率为11%。年龄和性别与接触该寄生虫无关联。猫之间的接触与捕猎（x2 = 4.98，p = 0.016）和喂养习惯（x2 = 13.34，p = 0.001）有关：喂食生肉的猫比喂食商业猫粮（x2 = 9.50，p = 0.004）或自制食物（x2 = 4.1，p = 0.027）的猫接触率更高。被诊断为刚地弓形虫感染慢性期的猫的频率为88%（15/17）。在所检测的50份粪便样本中，未发现任何刚地弓形虫卵囊。
