Felids are important in the epidemiology of Toxoplasma gondii infection because they are the only hosts that shed resistant oocysts in the environment. A total of 242 serum samples and 80 fecal samples from domestic cats in Latvia was tested for T. gondii infection. Serum samples were tested for T. gondii antibodies by an indirect in-house ELISA; antibodies were found in 125 (51.6%) of 242 cats; seroprevalence increased with age, indicating postnatal infection. Using multiple logistic regression analyses, age and outdoor access were found to be the most significant (F = 21.70, P < 0.05) factors associated with T. gondii infection in Latvia. Toxoplasma gondii -like oocysts were detected in 2 of the cats examined microscopically using the salt flotation method, but definitive diagnosis could not be made because a bioassay was not performed.
猫科动物在刚地弓形虫感染的流行病学中很重要，因为它们是唯一能在环境中排出具有抵抗力的卵囊的宿主。对拉脱维亚家猫的242份血清样本和80份粪便样本进行了刚地弓形虫感染检测。血清样本通过间接内部ELISA检测刚地弓形虫抗体；在242只猫中的125只（51.6%）检测到抗体；血清阳性率随年龄增加，表明是产后感染。通过多元逻辑回归分析发现，年龄和户外活动是拉脱维亚与刚地弓形虫感染相关的最显著因素（F = 21.70，P < 0.05）。使用盐浮选法在显微镜检查的2只猫中检测到了类似刚地弓形虫的卵囊，但由于未进行生物测定，无法做出明确诊断。
