摘要
从四川省种茧育家蚕分离出的一种小型微孢子虫SCM8,仅感染寄生家蚕的中肠上皮组织 ;孢子卵圆形 ,大小2 .82± 0 .2 0× 2 .1 9± 0 .1 3μm。孢子致病力较弱 ,感染中量 (IC50 )为 1 .2 9× 1 0 5粒 /ml;病程 1 2天以上。病理组织学和胚种传染的研究表明 。
Pathogenic microsporidia named SCM 8 were isolated from the silkworm larvae for egg production in Sichuan in 1997. In subsequent identification, this pathogen was found to infect the epithelial cells of the midgut only. The fresh spores were oval in shape and 2.82±0.20× 2.19 ±0.13μm in size.The pathogenicity of the spores was weak, with IC 50 being 1.29×10 5 spores/ml.The course of pathogenesis lasted 12 days or more. SCM 8 did not seem to have the capacity of transmission by egg.
