猫科动物在弓形虫感染的流行病学中很重要，因为它们是环境中唯一排出抗药性卵囊的宿主。对来自拉脱维亚家猫的242份血清样本和80份粪便样本进行了弓形虫感染检测。通过间接室内ELISA检测血清样本中的弓形虫抗体；在242只猫中发现125只(51.6%)抗体；血清阳性率随着年龄的增加而增加，表明出生后感染。运用多元Logistic回归分析发现，年龄和户外活动是与拉脱维亚弓形虫感染相关的最显著的因素(F=21.70，P<；0.05)。在用盐浮法进行显微镜检查的两只猫身上发现了弓形虫样卵囊，但由于没有进行生物测定，无法做出明确的诊断。
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.
