BACKGROUND
Toxoplasma gondii is a common protozoan parasite among all mammals, in particular small ruminants, worldwide. Traditional husbandry can be a major risk factor for infection of sheep and goats with this parasite.
OBJECTIVES
The present study aimed to determine the current status of the prevalence for T. gondii in livestock of Qazvin Province.
METHODS
In this cross-sectional study, the sera of 455 sheep and 375 goats were examined to detect anti-Toxoplasma IgG antibodies by using in-house indirect ELISA.
RESULTS
Overall, 33.62% (153/455) of sheep and 36.41% (130/375) of goats were positive for anti-Toxoplasma IgG antibodies with no statistically significant difference. The prevalence rate of T. gondii among the sheep of Qazvin County was significantly higher than in Abyek and Abhar counties (p < 0.001).
CONCLUSIONS
The results of the present study indicate that the prevalence of T. gondii in sheep and goats of the study area is high. Therefore, the meat of the animals reared in this area can be a potential source of human infections by this parasite.
背景
弓形虫是全球所有哺乳动物尤其是小型反刍动物中常见的原生动物寄生虫。传统养殖方式可能是绵羊和山羊感染这种寄生虫的主要风险因素。
目的
本研究旨在确定加兹温省家畜中弓形虫的流行现状。
方法
在这项横断面研究中，采用自制间接酶联免疫吸附测定法检测了455只绵羊和375只山羊的血清，以检测抗弓形虫IgG抗体。
结果
总体而言，33.62%（153/455）的绵羊和36.41%（130/375）的山羊抗弓形虫IgG抗体呈阳性，差异无统计学意义。加兹温县绵羊的弓形虫感染率显著高于阿比耶克县和阿巴尔县（p＜0.001）。
结论
本研究结果表明，研究区域内绵羊和山羊的弓形虫感染率很高。因此，该地区饲养动物的肉可能是人类感染这种寄生虫的潜在来源。
