Toxoplasma gondii is a zoonotic parasite, which is assumed to have cosmopolitan distribution.
Adopting a cross-sectional study design the current research aimed to determine the occurrence of the parasite in cattle, camels and sheep in Isfahan and Chaharmahal va Bakhtiary provinces of Iran.
Animals in the field and those brought for slaughter at abattoirs were included. Blood samples were randomly collected from animals and investigated by polymerase chain reaction (PCR).
T. gondii infections were detected in 0.00%, 6.60% and 17.9% of the sample cattle (n = 155), camels (n = 122) and sheep (n = 95) respectively. Sheep were more frequently affected in Chaharmahal va Bakhtiary (33.33%) compared to Isfahan (8.47%) (P = 0.005, 95%; CI = 6.88-43.35). No statistically significant difference was observed in infection prevalence between camels and sheep; and between the different sex categories in both camels and sheep.
Evidence of T. gondii occurrence in sheep and camels was provided in the provinces under study. There is a need to investigate the potential risk factors of zoonotic infections. Furthermore, animal health and production losses caused by the parasite; and associated zoonotic implications in the area under study need to be explored.
刚地弓形虫是一种人畜共患寄生虫，被认为在全球范围内均有分布。
本研究采用横断面研究设计，旨在确定伊朗伊斯法罕省和恰哈马哈勒-巴赫蒂亚里省牛、骆驼和绵羊体内该寄生虫的感染情况。
纳入农场中的动物以及送至屠宰场待宰的动物。随机采集动物血液样本，采用聚合酶链反应（PCR）进行检测。
在样本牛（n = 155）、骆驼（n = 122）和绵羊（n = 95）中，刚地弓形虫感染率分别为0.00%、6.60%和17.9%。与伊斯法罕（8.47%）相比，恰哈马哈勒-巴赫蒂亚里省的绵羊感染率更高（33.33%）（P = 0.005，95%；可信区间 = 6.88 - 43.35）。骆驼和绵羊的感染率以及骆驼和绵羊不同性别间的感染率均无统计学显著差异。
本研究省份提供了绵羊和骆驼感染刚地弓形虫的证据。有必要调查人畜共患感染的潜在风险因素。此外，还需探究该寄生虫导致的动物健康和生产损失，以及研究区域内相关的人畜共患影响。
