病原菌

Objective Bacteremia,or spesis patients with the distribution of pathogens and their common pathogens resistant analysis of the situation.

目的：了解菌血症或败血症患者病原菌分布及其常见病原菌耐药情况分析。

The main pathogen of neonate bacterial meningitis is Gram-positive coccus, whose distribution is correlated with neonatal pneumonia pathogens.

新生儿细菌性脑膜炎病原菌以革兰阳性球菌为主，其分布与新生儿肺炎病原菌有相关性。

The most feasible temperature for mycelial growth is 28~3TC and for conidial germination is 31~34癈; The most fitting pH for mycelial growth and conidial germination is 5~6;12 hours light and 12 hours dark by turns is benefit for mycelial growth, while light and dark have no influence on conidial germination, but ultraviolet radiation can kill the conidium?

其中最适于病原菌菌丝生长的温度为28～31℃，pH为5～6，12小时光暗交替有利于菌丝的生长。最适于病原菌分生孢子萌发的温度为31～34℃，pH为5～6，光照对孢子萌发没有显著影响，紫外光对孢子有杀伤作用，随着紫外光照射时间的增长，对孢子的杀伤力加大。

The results are showed as follow:1 The biological characteristics of the pathogenThe pathogen of Eucalyptus Dieback is Cylindrocladium quinqueseptatum Figueredo.

病原菌的生物学特性桉树焦枯病的病原菌是半知菌亚门丛梗孢目帚梗柱枝孢属的帚梗柱枝菌(Cylindrocladium quinqueseptatum Figueredo)。

The region between the circular brown band generated by cell lipid exosmosis and the band of the wound in the non-transgenic cotton Z35's leaves, is wider than that of the transgenic cotton T-34's leaves, and no micro-HR was found in Z35, the intensity of leaves wilting is much serious, by contrast, micro BR was found around the wound region within the transgenic cotton leaves inoculated with the pathogen, but the micro-HR was not found in the transgenic cotton treated with water and around wound region of non-transgenic cotton Z35 leaves which showed that there was micro-HR defence in transgenic hpa1xoo cotton.

棉花黄萎病菌侵染叶片后，非转基因棉花叶部伤口周围细胞无微过敏性反应，受病原菌侵染的叶片萎蔫程度较重；转hpa1xoo基因棉花叶部伤口周围细胞有微过敏反应，叶部刺伤处仅有较小的坏死斑，且不相连，发病较轻，而清水处理的转基因棉花与非转基因棉花叶片中伤口周围均无微过敏反应，说明病原菌侵染诱导转hpa1xoo基因棉花产生微过敏防御反应，转hpa1xoo基因棉花较非转基因棉花有较强的抗病性。

Incidence and disease index of Fusarium wilt disease were determined, and the plant growth index and changes of some secondary metabolites.

分别在接种病原菌之前和接种病原菌之后14 天收获植株样品，统计植株的发病率和病情指数，测定植株生长指标和其体内此生代谢物指标。

S. greville, Cortinarius russus and Laccaria laccata had the strongest restraint. They not only produced the most distinct inhibition zone and restrained the growth of pathogen, but also bestrowed pathogen and grew on it. It could be used for biological protetion and cure.

其中S.grevillei、Cortinarius russus、Laccaria laccata抑制作用最强，不仅产生最明显的抑菌环，抑制病原菌的生长，同时覆盖病原菌并在其上生长，可用来进行生物防治。

The past decade has seen a considerable amount of research worldwidely focused on lysin, and lysins have been used successfully in a variety of animal models to control pathogenic antibiotic resistant bacteria found on mucosal surfaces and infected tissues.

目前已建立了多种病原菌裂解酶应用的动物模型，在防控耐药性病原菌感染上取得重要进展。

They are not only involved in the process of fungal development and differentiation, such as supplying nutrition, for the growth of mycelium, attaching themselves to the morphosis and alteration of the cell wall of hyphae, as well as taking part in autolysis of filamentous fungi, but also show an important role in the process of pathogenesis including touching and cling on to the cell wall o.

1，3-葡聚糖酶(β-1，3-glucanase)是一类能够水解β-1，3-葡萄糖苷键的酶，普遍存在于多种真菌中，它们不仅在真菌生长发育起重要作用，如为菌丝体生长提供营养、参与菌丝体细胞壁的形态建成和构象的改变、参与菌丝体自溶等，而且在病原菌入侵寄主植物与致病的过程中扮演着重要角色，如：参与接触和吸附寄主细胞壁；破坏包围病原菌入侵结构的乳突。
