首次报道了马蹄叶腐烂病、红小豆溃疡病、黄花乌头顶枯病、江户菜软腐病和水飞蓟软腐病在吉林省的发生，详细描述了该五种病害症状及危害情况；通过对分离的病原菌的电镜形态观察、革兰氏染色、致病性、培养性状、生理生化性状、G+C mol％等方面的测定，依据《Bergey's Manual of determinative Bacteriology》9th ed相关部分，初步确定了其病原菌的分类地位并对病原菌进行了室内药剂筛选。

Gloeosporioides is an aggregative species and has differentiation within species, the pathogen probably is a microspecies under C. gloeosporioides and exhibited some specialized and selective qualities in pathogenicity. According to its symptom, the disease was named as angular leaf spot.

由于胶胞炭疽菌是1个集合种，存在分化现象，该病原菌可能是分化出的1个小种，并在致病性方面表现出一定的专化性或选择性，根据该病害的症状命名为板栗角斑病。

There are postulations that some positions of GP is the structural basis for some important biologic features of rabies virus, neurotropic, pathogenicity and antigenicity.

狂犬病毒GP基因上某些位点推测是狂犬病毒一些重要生物学特性，如：组织嗜性、致病性和免疫原性等的结构基础，因此这些部位的变异有可能导致这些特性的改变。

Rabies virus, the etiologic agent of fatal neurological disease, is composed of five stuctural proteins, both of the glycoprotein and the nucleoprotein are believed the decisive factors for rabies diagnosis and classification and for rabies neurotropic, pathogenicity and antigenecity.

狂犬病毒由五种结构蛋白组成，其中NP对狂犬病的诊断和分类；GP对狂犬病毒的组织嗜性、致病和免疫保护都起着决定性的作用，并且分离自不同宿主或不同地理位置的狂犬病毒之间存在着NP和GP抗原性差异，研究这种差异并结合流行病学资料有助于发现流行来源的线索。

Ten years wide investigation and research on the characteristics and pathogenicity of cryphonectria parasitica showed that, Cryphonectria parasitica existed widely in the distributing areas of Castanea mollissima, and that it belonged to weak parasite, only lived on the weak and dying branchs, sprouts, and soon. Cryphonectria parasitica was not main and direct death cause of Castanea mollissima, and the dead parts had no great influence on the growth of whole tree.

经过10余年对栗疫病发生特点和致病性的大量调查研究，结果表明栗疫菌在板栗分布区普遍存在，是弱寄生菌，在本地只寄生那些生长十分衰弱，即将死亡的板栗树干、苗木等，但栗疫菌的寄生不是这些部位死亡的主要和直接原因，而且它所寄生的部位局部死亡后对整株栗树的影响不大，因此，栗疫病在一般倩况下并非毁灭性病害。

Phytopathogenic bacteria employ Hrp pathogenicity island to encode a specific typeⅢsecretion system that is required for bacteria and host plant interaction.
