| 摘 要： | 本文报道:(1)体腔注射柞蚕空胴病病原菌——柞蚕链球菌(Streptococcus pernyi)能诱导柞蚕蛹产生抗菌物质。以柞蚕链球菌为诱导源,对29个柞蚕二化性品种和辽宁当地一化性品种滞育蛹的诱导试验表明:不同化性和不同品种之间诱导抗菌物质活性存在着明显的差异;(2)不同柞蚕品种滞育蛹诱导抗菌物质活性的产生和达到高峰的时间以及在体内持续时间的长短均有较大差异;(3)对五个不同类型的柞蚕二化性品种和辽宁当地一化性品种滞育蛹的诱导血淋巴进行了聚丙烯酰胺凝胶电泳谱的比较,初步表明,五个不同类型的二化性品种和辽宁当地一化性品种诱导产生抗菌物质的组份基本相同,但一化性品种的P9A和P9B的相对活性略高于二化性品种。

| Abstract: | Antibacterial substances could be induced in the haemolymph of diapausing pupoe of the Chinese tussah by injecting with viable pathogenic bacteria S . pernyi, The pathogen of empty-gut disease of A. pernyi. The quantitative variation of induced antibacterial substances in diapausiag pupae of 29 races, which belong to biviotine races and univotine races in Liaoning region of A. Pernyi, was compared and significant differences were observed. The time for induced antibacterial activity to reach its maximum after inducing differed with different races.The length of the period for induced antibacterial activity to be effective, also differed with different races. No significant difference among the induced products in 5 races was found. |
