Neospora caninum and Toxoplasma gondii are the protozoan parasites with definitive hosts from order Carnivora. Due to vertical transmission, both parasites can cause abortions and neonatal mortality that lead to significant productive and economic losses in the domestic ruminants. The aim of this study was to describe N. caninum and T. gondii seroprevalence in the group of frequently farmed captive exotic ruminants (n = 184) including Bovidae (barbary sheep, bezoar goat, common eland, American bison, water buffalo, and yak) and Camelidae (bactrian camel, guanaco, llama, and alpaca). Antibodies were tested by indirect fluorescent antibody test (IFAT) and enzyme-linked immunosorbent assay (ELISA). Higher prevalence of T. gondii antibodies (31% in IFAT and 52% in ELISA) was detected compared to N. caninum (24% in IFAT and 17% in cELISA). Mixed infection was found in 18 (10%) and 22 (12%) animals by IFAT and ELISA, respectively. Higher seroprevalence of both N. caninum and T. gondii was found in Camelidae compared to Bovidae. To author knowledge, this is the first detection of T. gondii and N. caninum antibodies in common elands and bezoar goats.
犬新孢子虫和刚地弓形虫是终末宿主为食肉目的原生动物寄生虫。由于垂直传播,这两种寄生虫均可导致流产和新生仔畜死亡,给家养反刍动物造成重大的生产和经济损失。本研究旨在描述常见养殖的圈养外来反刍动物(n = 184)群体中犬新孢子虫和刚地弓形虫的血清阳性率,这些反刍动物包括牛科动物(蛮羊、岩羊、普通大羚羊、美洲野牛、水牛和牦牛)和骆驼科动物(双峰驼、原驼、美洲驼和羊驼)。通过间接荧光抗体试验(IFAT)和酶联免疫吸附测定(ELISA)检测抗体。与犬新孢子虫(IFAT检测为24%,cELISA检测为17%)相比,刚地弓形虫抗体的阳性率更高(IFAT检测为31%,ELISA检测为52%)。分别通过IFAT和ELISA在18只(10%)和22只(12%)动物中发现了混合感染。与牛科动物相比,骆驼科动物中犬新孢子虫和刚地弓形虫的血清阳性率更高。据作者所知,这是首次在普通大羚羊和岩羊中检测到刚地弓形虫和犬新孢子虫抗体。
