在柞蚕软化病中,除已发现的一种由柞蚕链球菌引起的柞蚕空胴病(Tusseh emppty disease)外,最近又分离出一种新的病毒——柞蚕非包涵体病毒(Tusseh Nonccluded Viruse)。几年来,在细菌方面,我们从组织病理学入手开展了对多种类型的软化病的研究工作,从采集的样品中,培养、分离得到了大量的细菌,经反复筛选和测定,初步找出了对柞蚕致病力较强的十余株菌,并进行了菌株鉴定。现将结果简要报告如下。 In Tussah’s softening disease, in addition to Tusseh emppty disease, which has been found to be caused by Streptococcus tussah, a new virus, Tusseh Nonccluded Viruse, . In the past few years, in the field of bacteria, we started from the histopathology research on various types of softening disease, from the collected samples, culture, isolated a large number of bacteria, after repeated screening and determination, initially identified The stronger pathogenicity of tussah more than ten strains of bacteria, and strain identification. The results are briefly reported below.
