在机体内微生物之间为了生存、繁殖,有着这样或那样的关系。尤其在不同种属间的病原微生物为生存或致病,存在着明显的拮抗(干扰)或互生(协同)关系。研究病原微生物间存在的干扰和协同现象具有重要的理论意义和实用价值。 布氏菌病(简称布病)的流行病学调查报告显示:(1)从未在同一个体内同时分离到两个不同种的布氏菌或在较小范围内(一个畜群或较小的牧场内)几乎也从未分离出两个不同种布氏菌。(2)在羊种、
In the body of microorganisms in order to survive, reproduce, have this or that relationship. Especially in different species of pathogenic microorganisms for the survival or pathogenic, there is a clear antagonism (interference) or alternate (synergistic) relationship. Research on the interference and synergism between pathogenic microorganisms has important theoretical significance and practical value. Epidemiological investigation of brucellosis (brucellosis) reports that: (1) two different species of B. brucei have never been isolated in the same individual at one time or in smaller ranges (one herd or smaller Pasture) almost never separate two different species of brucella. (2) in sheep species,
