China, 571737Magnaporthe griseais the pathogenic fungus of rice many species of grass family. On rice, it causes rice blast, which is of economic important and world-wide distribution.

简称为MG是水稻和禾谷类作物及多种杂草的病原菌，所引起的水稻病害称稻瘟病，是全球水稻上最严重的真菌病害。

Soil samples were collected from different ecological conditions. More than 70 Streptomyces hygroscopicus strains were isolated from the soil samples. Fermentation centrifugal supernatant of the strains were used as biocontrol agents to bioassay the seedling of rice and barnyard grass and rice pathogens of sheath blightand bakanae. Three strains showed good effects of inhibitingbarnyard grass seedling, the another three strains well inhibited the growth of rice pathogenic fungi.

从国内外不同生态条件下采集的土壤标本中分离到70多个吸水链霉菌，用其发酵离心上清液对水稻、稗草秧苗和稻纹枯病菌、恶苗病菌进行生物测定，结果有3个菌株对稗草根的生长具有较好的抑效果；有3个菌株对水稻病原菌有很好的抑制生长作用。

The crude extracts of Sophora flavescens Ait were bioassayed by using growth-rate and pendant-drop methods for their fungicidal potential against six plant fungal pathogens at different concentrations.

采用生长速率法和悬滴法室内测试了不同浓度苦参提取物对葱菌核菌、番茄早疫菌、菜豆根腐菌、辣椒枯萎菌、黄瓜枯萎菌、茄子黄萎菌等6种蔬菜病原菌的抑菌活性。

World TB Day is observed each year on March 24 to commemorate the date in 1882 when Robert Koch announced the discovery of Mycobacterium tuberculosis, the bacterium that causes tuberculosis.

1882年的3月24日，罗伯特科赫首次发现结核杆菌，并阐明这种细菌是肺结核的病原菌。

Sixty five samples with csom were collected and cultured for anaerobic and aerobic bacteria separately.

结果 65例病人中，有62例检出病原菌，总检出率为95.4%。

In the case of soft rot, l6S Rdna PCR could be used to test the pathogen, and this work lay a foundation for rapid detection of soft rot in potato.

以马铃薯软腐病菌为代表，利用16SrDNA PCR进行鉴定，达到了预期的目的，为病原菌的快速鉴定方法提供了依据。

So we should mainly study it in Heilongjiang.,Several methods of identification of resistance to soft rot disease at seedling stage were studied with replicated orthogonal design.

本试验通过软腐病菌形态及生理生化特性对2001年8-10月份在黑龙江省各地采集的大白菜软腐病病样进行分析，结果表明：黑龙江省秋季大白菜软腐病的主要病原菌是欧文氏菌属中的胡萝卜软腐欧文氏菌胡萝卜软腐亚种，因此，我省在进行软腐病研究时，应该主要以该菌为主。

Obtained bacterial septicaemia, in addition, another successive pathogenic bacteria were also examined from a few diseased fish.

中，检出了原发感染的杀鲑气单胞菌，同时还在个别病死鱼中检出了作为继发感染的另一种病原菌。

As the kernel of BPY system, advanced wet degradation technology of waste comprises delivering sorted degradable organic substances into reactor, charging steam to perform wet degradation reaction under certain temperature and pressure for 1-2 hours, killing pathogenic bacteria and grass seeds to eliminate odor, synthesizing partially degraded substances into humus material, and preparing wet-degraded material into commercial fertilizer.

具有领先性的湿解技术是BPY系统的核心。应用湿解技术处理垃圾，将经过分选的可降解有机物输送到反应器内，通入蒸汽，在一定温度、压力和有水存在的条件下进行湿解反应，1～2小时杀灭病原菌和草籽，消除恶臭，同时使有机物的各种组份得到降解，并使部分降解后的物质再合成为腐殖质。然后将经过湿解处理的物料制成商品肥。

At the same time, the application of pathogen-induced promoters to broad-spectrum disease resistance gene engineering was also discussed in this research.

同时，本文还探讨了病原菌诱导型启动子在广谱抗病基因工程应用的可能性。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
