Opisthorchis viverrini is a zoonotic liver fluke that causes opisthorchiasis among humans in endemic areas, such as northeastern Thailand. The objective of this study was to determine the prevalence and risk factors for O. viverrini infection among cats and dogs in six districts surrounding Ubolratana Dam. Fecal samples of 1,018 dogs and 249 cats were collected between 2008 and 2013 to examine for O. viverrini infection using a modified formalin-ether concentration technique. The prevalence of O. viverrini infection among cats (77 of 249, 30.92%) was higher than dogs (2 of 1,018, 0.20%). Age and the eating habits of cats were associated with O. viverrini infection. Cats aged >3 years were more likely than those aged <1 year [Odds ratio (OR)=2.96; 95% confidence interval (95% CI): 1.01- 8.35; p = 0.044] of being infected. Cats that consumed raw fish were significantly more likely to be infected than those that consumed other foods (OR=1.82, 95% CI: 1.05-3.16; p = 0.032). Cats had a higher prevalence of O. viverrini infection than dogs and may play an important role in the transmission and maintenance of this disease in the study area.
猫后睾吸虫是一种人畜共患的肝吸虫，可在泰国东北部等流行地区导致人类感染肝吸虫病。本研究的目的是确定乌隆他尼大坝周边六个地区猫和狗感染猫后睾吸虫的患病率及风险因素。2008年至2013年期间收集了1018只狗和249只猫的粪便样本，采用改良的福尔马林-乙醚浓缩技术检测猫后睾吸虫感染情况。猫感染猫后睾吸虫的患病率（249只中的77只，30.92%）高于狗（1018只中的2只，0.20%）。猫的年龄和饮食习惯与猫后睾吸虫感染有关。年龄大于3岁的猫比年龄小于1岁的猫感染的可能性更高[比值比（OR）=2.96；95%置信区间（95%CI）：1.01 - 8.35；p = 0.044]。食用生鱼的猫比食用其他食物的猫感染的可能性显著更高（OR=1.82，95%CI：1.05 - 3.16；p = 0.032）。猫感染猫后睾吸虫的患病率高于狗，可能在该研究地区这种疾病的传播和维持中起重要作用。
