Three populations of small wild British rodents were studied by capture-recapture methods over a period of 3 years, a fourth group was studied for 1 year and a fifth was sampled annually for 4 years. Blood smears were taken from 3 species of rodents: the woodmouse Apodemus sylvaticus, the bank vole Clethrionomys glareolus (and an island sub-species C.g. skomerensis) and the short-tailed vole Microtus agrestis. The smears were examined microscopically. Four genera of haemoparasites Babesia, Hepatozoon, Trypanosoma and Grahamella were detected. Babesia was absent from C.g. skomerensis, Hepatozoon was rarely found in A. sylvaticus and M. agrestis and Trypanosoma was rare in A. sylvaticus. More males were infected than females but the difference was only statistically significant for the infection with Hepatozoon in adult C.g. skomerensis. Infections with Babesia and Hepatozoon were more prevalent in adult animals and infections with Trypanosoma were more prevalent in younger individuals. Only in C.g. skomerensis was there a significant difference between age classes in the prevalence of infection with Grahamella--there being more adults infected. Concurrent infections were detected, Hepatozoon being the parasite most commonly involved. The prevalence of infections was found to be approximately proportional to the number of animals known to be alive, regardless of the season.
在3年时间里，通过标记重捕法对英国三种小型野生啮齿动物种群进行了研究，第四组研究了1年，第五组每年抽样，持续了4年。从三种啮齿动物身上采集了血涂片：林姬鼠（Apodemus sylvaticus）、欧鼹（Clethrionomys glareolus，以及一个岛屿亚种C.g. skomerensis）和短尾田鼠（Microtus agrestis）。对涂片进行了显微镜检查。检测到了四种血液寄生虫属：巴贝斯虫属（Babesia）、肝簇虫属（Hepatozoon）、锥虫属（Trypanosoma）和格雷厄姆氏体属（Grahamella）。在C.g. skomerensis中未发现巴贝斯虫属，在林姬鼠和短尾田鼠中很少发现肝簇虫属，在林姬鼠中锥虫属很少见。感染的雄性比雌性多，但这种差异仅在成年C.g. skomerensis中肝簇虫属感染方面具有统计学意义。巴贝斯虫属和肝簇虫属感染在成年动物中更为普遍，锥虫属感染在较年轻个体中更为普遍。只有在C.g. skomerensis中，格雷厄姆氏体属感染率在不同年龄组之间存在显著差异——成年动物感染更多。检测到了混合感染，肝簇虫属是最常涉及的寄生虫。发现感染率与已知存活的动物数量大致成比例，与季节无关。
