Abstract

A study was performed in order to determine helminths of laboratory animals. Fecal specimens obtained from 110 mice, 263 rats and 65 rabbits were investigated and 37 rats and 7 rabbits were necropsied. In general, 83.8% rats were found to be infected by necropsy, while 100% of mice,and 81.8% of rats were found to be infected with one or more helminths species by fecal examination. No rabbits were found to be infected by necropsy or fecal examination. In fecal examination of mice and rats, the prevalence of helminths was detected as follows: Syphacia muris, 100%; Aspicularis tetraptera, 53.6%; Syphacia obvelata, 46.4%; and Hymenolepis diminuta 17.9% in mice. The prevalence in rats was H. Diminuta, 62.5%; S. muris, 25%; Hymenolepis nana, 6.8%; and Trichosomoides crassicauda, 6.8%. In necropsy, S. muris was identified in all of infected rats, but only one was infected with A. tetraptera.

摘要

为了确定实验动物体内的蠕虫，开展了一项研究。对从110只小鼠、263只大鼠和65只兔子采集的粪便样本进行了调查，并对37只大鼠和7只兔子进行了尸检。总体而言，通过尸检发现83.8%的大鼠受到感染，而通过粪便检查发现100%的小鼠和81.8%的大鼠感染了一种或多种蠕虫物种。通过尸检或粪便检查未发现兔子受到感染。在小鼠和大鼠的粪便检查中，蠕虫的感染率检测结果如下：小鼠中，鼠管状线虫为100%；四翼无刺线虫为53.6%；椭圆管状线虫为46.4%；微小膜壳绦虫为17.9%。大鼠中的感染率为：微小膜壳绦虫62.5%；鼠管状线虫25%；缩小膜壳绦虫6.8%；粗尾 Trichosomoides crassicauda 6.8%。在尸检中，在所有受感染的大鼠中都鉴定出了鼠管状线虫，但只有一只感染了四翼无刺线虫。
