is a ubiquitous intracellular parasite with felids as definitive hosts and a broad range of intermediate hosts. Rodents are considered suitable sentinels for prevalence studies of many infections, including toxoplasmosis. This study aimed to estimate the seroprevalence of in rodents from different localities of Slovakia and investigate the correlation between the seropositivity and the species, age, sex, and sexual activity of animals. Altogether, 1009 wild rodents belonging to 9 species were trapped in 2015 and 2019, and antibodies to were detected in 6.7% of the animals. Seropositivity was detected in seven species, ranging from 0.0% in and to 7.7% in . The females reached significantly higher seropositivity (9.7%) than the males (3.8%), and the adults were positive significantly more often (9.2%) than the subadults (4.9%). The seropositivity differed also among localities, with significantly higher positivity detected in suburban and touristic areas (12.2%) than in localities with a lower level of human activities (5.5%). This study showed that the occurrence of varies significantly in rodent species and habitats with various environmental conditions and different levels of anthropic use. Several biological and ecological factors, e.g., soil contamination, soil conditions, the susceptibility of rodent species etc., may influence this variability.
是一种普遍存在的细胞内寄生虫，以猫科动物为终末宿主，中间宿主范围广泛。啮齿动物被认为是许多感染（包括弓形虫病）流行率研究的合适哨兵。本研究旨在估计斯洛伐克不同地区啮齿动物中的血清阳性率，并调查血清阳性与动物的物种、年龄、性别和性活动之间的相关性。2015年和2019年共捕获了属于9个物种的1009只野生啮齿动物，其中6.7%的动物检测到抗的抗体。在7个物种中检测到血清阳性，范围从和中的0.0%到中的7.7%。雌性的血清阳性率（9.7%）显著高于雄性（3.8%），成年动物的血清阳性率（9.2%）显著高于亚成年动物（4.9%）。不同地区的血清阳性率也有所不同，郊区和旅游区的阳性率（12.2%）显著高于人类活动水平较低地区（5.5%）。本研究表明，在具有不同环境条件和不同人类利用水平的啮齿动物物种和栖息地中，的发生率差异显著。一些生物学和生态学因素，如土壤污染、土壤条件、啮齿动物物种的易感性等，可能会影响这种变异性。
