Abstract

Toxoplasma gondii is a parasite responsible for toxoplasmosis, an emerging and often neglected zoonosis in South America, particularly Brazil. Felines, the only definitive hosts, excrete oocysts in their feces, potentially infecting all homeotherms. Domestic cats are primarily responsible for contaminating human environments with these oocysts. Monitoring their populations is therefore essential to ensure proper toxoplasmosis prophylaxis. The aim of this study was to estimate the prevalence of T. gondii and exposure factors in a population of owner cats in the city of João Pessoa, Paraíba, Brazil. A total of 267 blood samples were collected from domestic cats aged between 1 and 15 years and tested with an immunofluorescence antibody test. The seroprevalence of antibodies against T. gondii was only 17.22% (46/267 individuals). This result therefore suggests a low contribution of domestic cats to T. gondii contamination of the urban environment. The cats' age and living environment were identified as risk factors for cat exposure to T. gondii.

帕拉伊巴州（巴西）家猫的地质流行病学、血清流行率以及与弓形虫感染相关的因素。

弓形虫是导致弓形虫病的寄生虫，在南美洲，尤其是巴西，这是一种新出现的、经常被忽视的人畜共患疾病。猫科动物是唯一的宿主，它们在粪便中排出卵囊，可能感染所有同温动物。家猫是这些卵囊污染人类环境的罪魁祸首。因此，监测家猫的数量对于确保适当的弓形虫预防措施至关重要。本研究的目的是估算巴西帕拉伊巴州若昂佩索阿市家猫群体中冈地弓形虫的流行率和接触因素。研究人员从年龄在 1-15 岁之间的家猫身上共采集了 267 份血液样本，并用免疫荧光抗体测试法进行了检测。淋球菌抗体的血清阳性率仅为 17.22%（46/267 只）。因此，这一结果表明，家猫对城市环境中的淋球菌污染影响较小。猫的年龄和生活环境被认为是猫感染淋病的风险因素。

期刊介绍： Parasite is an international open-access, peer-reviewed, online journal publishing high quality papers on all aspects of human and animal parasitology. Reviews, articles and short notes may be submitted. Fields include, but are not limited to: general, medical and veterinary parasitology; morphology, including ultrastructure; parasite systematics, including entomology, acarology, helminthology and protistology, and molecular analyses; molecular biology and biochemistry; immunology of parasitic diseases; host-parasite relationships; ecology and life history of parasites; epidemiology; therapeutics; new diagnostic tools. All papers in Parasite are published in English. Manuscripts should have a broad interest and must not have been published or submitted elsewhere. No limit is imposed on the length of manuscripts, but they should be concisely written. Papers of limited interest such as case reports, epidemiological studies in punctual areas, isolated new geographical records, and systematic descriptions of single species will generally not be accepted, but might be considered if the authors succeed in demonstrating their interest.
