Abstract

Wild mice and voles were tested for Cryptosporidium during a 2-year survey at an agricultural site in Warwickshire, United Kingdom. C. parvum and C. muris, the two cryptosporidial species known to infect mammals, were detected. Prevalence figures of 22%, 21% and 13% noted for C. parvum for Mus domesticus, Apodemus sylvaticus and Clethrionomys glareolus, respectively, were higher than those recorded for C. muris at 10%, 6% and 2%. C. parvum causes the sometimes severe diarrhoeal disease cryptosporidiosis in many hosts, but the wild rodents were asymptomatic. The discovery of C. muris in A. sylvaticus and C. glareolus confirms a wider distribution in wild rodents than has previously been reported. Rodents may represent a significant reservoir of Cryptosporidium with a high potential for infection of man and livestock due to cohabitation.

摘要

在英国沃里克郡的一个农业地点进行的为期两年的调查中，对野生小鼠和田鼠进行了隐孢子虫检测。检测到了已知感染哺乳动物的两种隐孢子虫物种——微小隐孢子虫和鼠隐孢子虫。小家鼠、林姬鼠和棕背䶄的微小隐孢子虫患病率分别为22%、21%和13%，高于鼠隐孢子虫的患病率，分别为10%、6%和2%。微小隐孢子虫在许多宿主中会引发有时较为严重的腹泻病——隐孢子虫病，但野生啮齿动物没有症状。在林姬鼠和棕背䶄中发现鼠隐孢子虫，证实其在野生啮齿动物中的分布比之前报道的更广。由于与人类和牲畜同居，啮齿动物可能是隐孢子虫的一个重要储存宿主，对人类和牲畜具有很高的感染潜力。
