T is phenotypically similar to the systemic acquired resistance induced by the infection of pathogens, and with the same efficiency but without hypersensitive response and visible symptoms in plant as SAR, which is helpful to open a new way to develop and improve safer and environmentally friendly strategies for plant protection.

SR具有非特异性、广谱性和系统性，其在表型上与病原菌侵染激发的系统获得抗性相似，具有同样的效率；但在寄主植物上不发生过敏性坏死反应，无可见症状，为发展和改善更加安全而环境友好的植物保护策略开辟了新的思路。

The purpose of this study is to screen microorganisms with growth inhibition against plant fungal pathogens. The plate-dilution method was used to isolate the bacteria from salt marshes at Dafeng, Jiangsu. The antifungal activity of the bacterial broth filtrates against 5 phytopathogens was determined using mycelial disk method. The antifungal compositions of four active bacteria were analyzed primarily with chromatography techniques. Two hundred and thirty-five aerobic (92) and anaerobic (143) bacterial strains have been isolated from the coast salt marsh and sixty-five strains, of which 39 are aerobic and 26 are anaerobic showed greater than 30% of inhibition rate against the growth of at least one of the phytopathogenic fungi on petri dish.

为了开发对植物病原真菌生长有抑制作用的药源微生物，本实验采用平板稀释法从江苏大丰盐沼湿地土壤中分离微生物，并通过菌丝块法检测这些微生物代谢产物对5种植物病原真菌生长的抑制活性，进而利用柱层析分析其活性成分；结果共分离得到235株细菌，其中好氧细菌92株，厌氧细菌143株；体外活性测试结果显示有65株至少对1种测试植物病原真菌的抑制率在30%以上，其中好氧菌39株，厌氧菌26株。

Methods Acanthamoeba polyphaga and Legionella pneumophila were co-cultured under laboratory condition. At consecutive time points during the culture, smears of the cultured products were made on glass slides for staining purposes. Different types of stainings including Gram′s staining, Gimenez staining, Giemsa staining and immunofluorescence were used to determine the best method for the identification of amoebal pathogens.

方法嗜肺军团菌与多噬棘阿米巴共培养，取不同时点的共培养物制作涂片，采用革兰氏染色、吉曼尼兹染色、姬姆萨染色、免疫荧光染色等多种方法，用光学显微镜及荧光显微镜观察鉴别阿米巴滋养体与其胞内嗜肺军团菌，并比较这些染色方法的效果。

RESULTS The Gram-positive cocci were 135 cases in 207 caes patients of bloody infection (56.2%). The proportion of opportunistic pathogens rose (P＜0.05 or P＜0.01). The incidence of children was higher than adult (58:42). The infant of ＜1 year was 36.2%. The newborn of＜30d was 31.4%.192 cases patients(92.8%) had protopathy or complicating diseases. No-normal birth was important susceptible factor to nowborn of bloody infection. The septicemia of Gram-negative bacillus, nowborn of no-normal birth and other septicemia of be accompanied by severe disease were main cause of death in our guoup.

结果 207例血液感染以G＋球菌为主(56.2％)，且条件致病菌感染有增多趋势(P＜0.05或P＜0.01)；儿童发病显著高于成人(58：42)，其中＜1岁婴幼儿占36.2％，＜30d新生儿占31.4％；192例(92.8％)有原发病或夹杂病；非正常生产已成为了新生儿血液感染的重要易感因素；G－杆菌败血症、不正常分娩新生儿以及伴有严重疾病的其他败血症患者是本组病例的主要死亡原因。
