Abstract

This communication aimed to determine the frequency of infection by T. gondii and other gastrointestinal parasites in free-living cats captured in BioParque do Rio (Fundação RioZoo), Brazil. To this end, 58 blood and 51 fecal samples were collected from 68 cats from July 2019 to September 2020. The serum obtained was analyzed by indirect fluorescent antibody test for anti-T. gondii IgG. Fecal samples were examined by microscopic parasitological techniques. Of the total, 10.3% of the animals presented anti-T. gondii IgG. Parasitic structures were observed in 39.2% of the fecal samples. Hookworms were the most detected parasites (19.6%) followed by Cystoisospora sp. (11.7%), Dipylidium caninum (7.8%) and Toxocara cati (3.9%). These results indicated the exposure of this population of stray cats to potentially zoonotic parasites, which in addition to causing possible damage to domestic and wild animal health, also pose risks to public health.

里约热内卢动物园散养猫体内弓形虫和其他胃肠道寄生虫的发生率。

本通讯旨在确定在巴西里约生物广场（Fundação RioZoo）捕获的自由生活的猫感染淋球菌和其他胃肠道寄生虫的频率。为此，2019 年 7 月至 2020 年 9 月期间，从 68 只猫身上采集了 58 份血液样本和 51 份粪便样本。获得的血清通过间接荧光抗体测试分析抗淋病双球菌 IgG。粪便样本采用显微寄生虫学技术进行检测。其中，10.3%的动物出现了抗淋病双球菌 IgG。39.2%的粪便样本中观察到寄生虫结构。钩虫是检测到最多的寄生虫（19.6%），其次是囊虫（11.7%）、犬双鞭毛虫（7.8%）和弓形虫（3.9%）。这些结果表明，该流浪猫群中可能存在人畜共患病寄生虫，这些寄生虫除了可能对家畜和野生动物的健康造成损害外，还对公众健康构成威胁。
