is an intracellular protozoan and a major foodborne pathogen worldwide. Nearly, all warm-blooded animals are susceptible to toxoplasmosis, with raw and undercooked meat and animal products serving as the primary transmission routes. To date, the distribution of among farm animals in Kazakhstan has been inadequately studied. This study aimed to determine the occurrence of antibodies against in cattle and sheep in the Akmola and Kostanay regions.
Blood samples were randomly collected from 437 cattle and 397 sheep from two regions of Kazakhstan: Akmola and Kostanay. A commercial enzyme-linked immunosorbent assay based on the native protein surface antigen 1 was used for serological analysis.
The occurrences of were 8.0% and 3.8% among cattle and 42.1% and 19.0% among sheep in the Akmola and Kostanay regions, respectively. Antibodies against were detected in all study areas. The greatest frequency of seropositive reactions in cattle was observed in the Arshaly region (9.0%), whereas the least frequent was observed in Arkalyk (3.3%). The highest occurrence of seropositive reactions among sheep was found in the Zerenda region (54.5%), whereas the lowest was found in the Auliekol region (15.6%).
The obtained results confirmed the circulation of the pathogen among cattle and sheep in the investigated regions. These findings provide insight into the current distribution of this zoonotic parasite among farm animals in Kazakhstan.
[病原体名称]是一种细胞内原生动物，也是全球主要的食源性病原体。几乎所有温血动物都易感染弓形虫病，生的和未煮熟的肉类及动物产品是主要传播途径。迄今为止，哈萨克斯坦农场动物中[病原体名称]的分布情况研究不足。本研究旨在确定阿克莫拉和科斯塔奈地区牛和羊中抗[病原体名称]抗体的存在情况。
从哈萨克斯坦的两个地区阿克莫拉和科斯塔奈随机采集了437头牛和397只羊的血样。基于天然蛋白[病原体名称]表面抗原1的商业酶联免疫吸附测定用于血清学分析。
阿克莫拉和科斯塔奈地区牛的[病原体名称]感染率分别为8.0%和3.8%，羊的感染率分别为42.1%和19.0%。在所有研究区域均检测到抗[病原体名称]抗体。牛血清阳性反应频率最高的是阿尔沙利地区（9.0%），而最低的是阿尔卡雷克（3.3%）。羊血清阳性反应发生率最高的是泽伦达地区（54.5%），而最低的是奥列伊科尔地区（15.6%）。
所得结果证实了[病原体名称]病原体在被调查地区的牛和羊中传播。这些发现为这种人畜共患寄生虫在哈萨克斯坦农场动物中的当前分布情况提供了见解。
