Approximately 73% of wild caught field rats were found infected with schistosomiasis japonica as revealed by the finding of eggs in liver sections; 49% of rats showed eggs in histological sections of the large intestine and about 13% showed eggs in their stools. Male rats appear to have higher schistosomiasis infection rate then female rats and that rats caught from endemic areas with smooth or normal looking livers do not necessarily mean that they are not infected with schistosomiasis. Examination for miracidia using only 2-3 pellets of field rat's stool by Faust-Meleney egg hatching technique revealed that 58% of them were positive with a mean of 5 miracidia per rat. A slightly lower hatchability rate was observed among laboratory infected white rats. Our figures on hatchability of Schistosoma ova are higher than those obtained by Pesigan and his co-workers probably because we used freshly collected rat faeces.
通过肝脏切片中发现虫卵表明，约73%的野生捕获田鼠感染了日本血吸虫病；49%的大鼠在大肠组织切片中发现虫卵，约13%的大鼠粪便中发现虫卵。雄性大鼠的血吸虫病感染率似乎高于雌性大鼠，而且从流行地区捕获的肝脏外观光滑或正常的大鼠并不一定意味着它们未感染血吸虫病。采用福斯特-梅勒尼虫卵孵化技术，仅用2-3粒田鼠粪便检测毛蚴，结果显示58%呈阳性，每只大鼠平均有5条毛蚴。在实验室感染的白鼠中观察到孵化率略低。我们关于血吸虫卵孵化率的数据高于佩西甘及其同事获得的数据，可能是因为我们使用的是新鲜采集的大鼠粪便。
