弓形虫病是一种常见的人畜共患病，由弓形虫引起。然而，关于T.俄罗斯人类和家畜的弓形虫感染。因此，在本研究中，T。在俄罗斯山羊的弓形虫进行了调查。共调查32个羊场216只山羊，其中95只羊血清学阳性。刚地。受检地区之间的血清阳性率差异无统计学意义。接下来，我们在俄罗斯鞑靼斯坦共和国的首府喀山市收集了99只猫和181个人的血清样本，并检查了他们的T。弓形虫血清阳性99份猫样本中的39份和181份人样本中的56份显示血清阳性。对数回归分析显示，人类受试者的养猫史，而不是他们的性别或年龄是T。弓形虫血清阳性这些发现表明，俄罗斯的自然环境可能受到T。猫排出的弓形虫卵囊，这些卵囊的摄入为人类感染这种寄生虫提供了主要途径。
Toxoplasmosis, a most common zoonosis, is caused by the protozoan parasite Toxoplasma gondii. However, there is little epidemiological information on T. gondii infections in humans and livestock animals in Russia. Therefore, in this study, the seroprevalence of T. gondii in goats in Russia was investigated. A total of 216 goats from 32 farms were investigated and 95 of them were seropositive for T. gondii. The difference in seroprevalence between the examined regions was not statistically significant. We next collected serum samples from 99 cats and 181 humans in Kazan city, the state capital of the Republic of Tatarstan, Russia, and examined their T. gondii seroprevalences. Thirty-nine of the 99 cat samples and 56 of the 181 human samples showed seropositivity. Logistical regression analysis revealed that the cat breeding history of the human subjects, but not their sex or age is a significant risk factor for T. gondii seropositivity. These findings suggest that the natural environment in Russia may be widely polluted with T. gondii oocysts shed by cats, and ingestion of these oocysts provides a major route for human infection with this parasite.
