To obligatory pathogens like Pseudoperonospron cubensis, it could not only hold back the infection of hypha,but also heal the spot where infected by hypha.(8)The study on mechanism of action showed that the crude extract of S-5210 had a strong inhibition of the mycelia growth and spore germination which led to some abnormal growth such as the twisted and inflated mycelia, the abnormal increased branching, the broken mycelia wall and leakage of cytoplasm from hyphal tips.Alao the spores and the rate of germination were decreased, the germ tube was malformed in shape et al.The pathogenicity of hypha and spore was weakened.

菌根常常可以导致根部病原菌的控制，但是在叶部病原菌上却直到了相反的作用。

objective to study the infection and sensitivity to antimicrobial agents of staphylococcus of bacterial prostatitis patients.methods the results of bacteriology and drug susceptibility of 421 patients,who were suffered from prostatitis,were analysed retrospectively.results in the 421 succus prostaticus samples,278 strains pathogenic microorganisms of 15 genera were isolated from the 273 succus prostaticus samples,and the major pathogenic microorganisms was staphylococcus aureus(57.2%) and coagulase negative staphylocous（17.3%.the drug resistance rate of staphylococcus to penicilling,erythromycin and albomycin was 88%-97%,and it was 33%-50% to fluoroquinolones.the drug resistance rate of staphylococcus to amikacin,cefazolin,nemycin,rifampicin and cefoperazone was lower than 30%,and they all appeared susceptible to vancomycin.conclusion staphylococcus is the main germ of bacterial prostatitis and it appears high drug resistance to usual antibacterials.staphylococcus is susceptible to vancomycin,amikacin,cefazolin,neomycin,rifampicin and cefoperazone.

目的 探讨细菌性前列腺炎患者葡萄球菌的感染状况及抗菌药物敏感性。方法回顾分析421例前列腺炎患者标本的细菌学和药物敏感性试验结果。结果 421例前列腺液标本，273例分离出细菌，共分离出15个种别共计278株病原菌，其中金黄色葡萄球菌占57.2%，凝固酶阴性葡萄球菌占17.3%；葡萄球菌对青霉素g、红霉素、白霉素耐药率为88%～97%，对氟喹诺酮类耐药率为33%～50%，对丁胺卡那霉素、头孢唑啉、新霉素、利福平和头孢哌酮耐药率均0%，对万古霉素全部显示敏感。结论葡萄球菌是细菌性前列腺炎的最常见病原菌，对临床常用抗菌药物具有较高的耐药性，葡萄球菌对万古霉素、丁胺卡那霉素、头孢唑啉、新霉素、利福平和头孢哌酮较为敏感。

Results:No bacteria could be isolated from the prostates of the normal rats, but positive isolation was achieved from the prostates of the infected animals 28th day after infection.

各BP治疗组动物的前列腺组织内病原菌的数量随给药时间延长而逐渐明显减少，在给药第5 d后91.7％的动物的前列腺组织已不能检出病原菌。

Biological characteristics of the pathogen and the resistance of 13 cultivars of tea plant to tea brown blight were studied by means of natural infection in the field and artificial inoculation in vitro. Resistant cultivars and susceptible cultivars of tea plant were divided. And the resistance mechanism was researched tentatively. The findings are as follows: 1 Some biological characteristics of the pathogenic fungus The experiment result showed: the optimum temperature for the growth of fungus mycelium was from 24 to 27℃, the optimum temperature for sporulation ranged 22 to 30℃. Treated at 54℃ in 10 minutes, the spores didn't germinate. The optimum pH for the growth of the mycelium was 5.1～5.9, the optimum pH for sporulation ranged 5.0～6.0. Light had no much effect on the growth of fungus mycelium, but had much effect on the reproduction of the spore.

首先，研究了茶云纹叶枯病病菌的生物学特性；其次，通过田间抗性调查和室内人工接种鉴定，对 13 个茶树品种进行了抗病性鉴定；第三，在前人研究的基础上，对茶树抗病机理作了更深入的研究，结果发现： 1 病原菌的生物学特性病原菌的分生孢子萌发的最适温度范围为 24～27℃，菌丝生长的最适温度范围为 22～30℃；致死温度为 55℃；菌丝生长的最适 pH 范围为 5.1～5.9，孢子萌发的最适 pH 范围是 5.0～6.0；光照对病菌生长速度及分生孢子萌发影响不大，但对其产孢的影响很大，特别是有光照与无光照处理之间差异显著，光照有利于分生孢子的形成。

Typical soft rot symptoms appeared in one day after inoculation with an inoculum density of 106 CFU/mL at 20-30℃.

接种试验中，在16℃及26℃发病，在28℃及30℃的供试温下，病原菌接种密在103CFU/mL时会发病；在20至30℃的供试温下，病原菌接种密为106CFU/mL以上时，只要一天就会出现典型的软腐病徵。

Genes involved in interactions among plants and pathogens,pathogenicity related genes,and the genes encoding bactericidal peptide,which have been studied in order to promote resistance to soft rot.

目前已有大量研究证实，利用植物与病原菌互作的相关基因、病原菌致病性的相关基因以及杀菌肽基因可以或有望提高植物对软腐病的抗性。
