Toxoplasmosis is an important zoonotic disease worldwide caused by the intracellular parasite Toxoplasma gondii. Cats, being hosts, act as a good sentinel for this disease. Thus, the objective of this study was to determine the seroprevalence of T. gondii in cats by examining serum from seven districts of Metropolitan Lima, Peru. We collected and analyzed 303 cat serum samples, and the owners answered a questionnaire about age, gender, lifestyle (indoors only and outdoors access) and feeding (commercial and home food). The samples were tested using indirect hemagglutination (IHA) for detection of antibody IgM and IgG. Among the animals analyzed, we found 52 (17.2%, 95% CI: 13.1% - 21.9%) seropositive cats to T. gondii, of which one corresponded to acute infection (IgM) and 51 to chronic infections (IgG). In addition, the presence of anti-T. gondii antibodies was associated with feeding commercial food and living outdoors access. Our results concluded that T. gondii infections are common in cats with owners in Metropolitan Lima and will be useful to future epidemiological studies.
弓形体病是一种重要的全球动物源性传染病，由细胞内寄生虫刚地弓形虫引起。猫作为宿主，是这种疾病的良好监测者。因此，本研究的目的是通过检查秘鲁利马都会区七个区的猫血清来确定 T. gondii 的血清流行率。我们收集并分析了 303 份猫血清样本，主人回答了一份关于年龄、性别、生活方式（仅限室内和室外活动）和喂养方式（商业和家庭食物）的问卷。使用间接血凝法（IHA）检测抗体 IgM 和 IgG 来检测样本。在分析的动物中，我们发现 52 只（17.2%，95%置信区间：13.1% - 21.9%）猫血清对 T. gondii 呈阳性，其中一只对应急性感染（IgM），51 只对应慢性感染（IgG）。此外，抗 T. gondii 抗体的存在与食用商业食物和户外活动有关。我们的研究结果表明，利马都会区猫主人的 T. gondii 感染很常见，这将对未来的流行病学研究有用。
