摘要
从不同地区养蚕生产及桑园害虫中分别收集到四种微孢子虫，ＭＡ—１、ＭＤ—１、Ｐｈａ—Ｍ和Ｈａ—Ｍ。从它们孢子的形态、对蚕的致病性、相互间的血清学关系、在蚕体内的寄生部位和引起的组织与细胞病变以及在蚕体内增殖的生活史等方面与典型的家蚕微粒子病病原Ｎｏｓｅｍａｂｏｍｂｙｃｉｓ进行了比较研究。结果表明，ＭＡ—１与Ｎ．ｂｏｍｂｙｃｉｓ相同；Ｈａ—Ｍ可能亦来源于Ｎ．ｂｏｍｂｙｃｉｓ；ＭＤ—１为Ｎ．ｂｏｍｂｙｃｉｓ的形态变异株，定名为Ｎ．ｂｏｍｂｙｃｉｓｍｏｒ．ｖａｒ．；而Ｐｈａ—Ｍ为与Ｎ．ｂｏｍｂｙｃｉｓ不同的种，暂称为Ｎｏｓｅｍａｓｐ。
Four kinds of microsporidian spores,different in morphology and in pathogenicity tosilkworm,Bombyx mori,were collected from silkworms and wild insects,i. e. MA-1 andMD-1 from silkworm rearing production,Pha-M from a mulberry insect Phyllobroticaarmata in Sichuan Province and Ha-M from mulbeery looper,Hemerophila atrilineata,in Zhenjiang area. Their spore morphology,pathogenicity to silkworms,serological rela-tionships,parasitizing sites and pathological changes in infected tissues and cells insidethe silkworm body,and their life cycle were compared respectively with Nosema bomby-cis,the typical pebrine pathogen of the silkworm,The results showed that MA 1 is thesame as N. bombycis;Ha M probably also comes from N. bombycis;MD 1 is a morpho-logical variation of N. bombycis designated as N. bombycis mor. var;while Pha M is anew microsporidia pathogenic to the silkworm,called Nosema sp..
