据鉴定,在一群BALB/c系纯合子裸小鼠中,小鼠肝炎病毒与严重的鼠管状线虫(Syphacia obvelata)和Aspicularis tetraptera的混合感染,为引起高度死亡率的病因。对2种寄生虫用寄生虫学方法(粪检与盲肠和直肠内容物检验)与组织学技术(小肠和大肠切片染色检查)作了比较。其中粪检结果与另两种方法很不一致。在盲肠内容物中可检出该2种(虫入)虫的胚卵和各成虫期;组织学检查也证实有严重感染。对各种抗(虫入)虫治疗方法进行比较,
It has been identified that a mixed infection of mouse hepatitis virus with severe Syphacia obvelata and Aspicularis tetraptera in a group of BALB / c homozygous nude mice is the cause of a high mortality. Parasitology methods for both parasites (fecal and cecal and rectal contents tests) and histological techniques (small and large intestine sectioned staining tests) were compared. The results of fecal examination and the other two methods are very inconsistent. The embryo eggs and the adult stages of the two species of insects (worms) were detected in the contents of the cecum; histological examination also confirmed severe infection. A variety of anti (insect into) worm treatment methods were compared,
