摘　　要：侵染桑树的病原原核生物有细菌、菌原体、螺原体、立克次体等,其中由病原细菌引发的桑树细菌病害对蚕桑生产的危害极大。主要介绍原核生物界薄壁菌门的病原细菌侵染桑树导致的桑疫病、桑青枯病、桑枝软腐病、桑枯萎病和桑叶斑病等重要桑树细菌病害,从病原及其侵染循环,桑树发病规律、发病症状,病害防治方法几个方面概述其研究进展。Pathogenic prokaryotes infecting mulberry include bacteria, mycoplasms, spiroplasmas and rickettsia, among which mulberry bacterial diseases caused by pathogenic bacteria greatly endanger sericultural production. This paper mainly introduces important mulberry bacterial diseases including mulberry bacterial blight, mulberry bacterial wilt, mul- berry shoot soft rot, mulberry enterobacterial wilt and mulberry bacterial leaf spot caused by infection of pathogenic bac- teria from Gracilicutes of Prokaryota. The research progress in pathogens and their infection cycle, mulberry disease on- set and disease symptoms, and control measures aaainst mulberry diseases was reviewed.
