Methods After Candida albicans were inoculated into the specific pathogen free mice, the total amount of Candidas in cecum and the amount of which attached to the mucosal membrane were counted at different interent intervals. The lymphocyte proliferation in Peyer's patch and in lamina proper was shown by BrdU incorporation, meanwhile B cells isotype switch in PP was investigated. IgA plasma cells were shown by immunohistochemical staining. Specific IgA antibodies to Candida albicans were measured with ELISA.

Henn. Ito et Imai and Ciboria carunculoides(Siegl.et Jenk) Whetz.et Wolf,occurred,and each kind of pathogeny had its own distinct biological characters.

通过对崇明县松外松果桑园内桑椹的发病症状及其病原的调查表明，园内有3种菌核病发生，分别为桑椹肥大性菌核病、桑椹缩小性菌核病和桑椹小粒性菌核病，其病原菌的生物学特性明显不同。

Physical, chemical and biological agents were main elicitors being applied, which can change morphology, physiology and biochemistry to improve the natural disease resistance.

能够有效诱导果蔬采后抗病性的因子主要有物理、化学、生物等，其机理是通过生态学和生理生化的变化来提高果蔬对病原菌的抗病性。

Conclusion］ The tobacco will be taken bad because of actions of 2 strains bacterial endophytes isolated from Enterobacter Hormaeche under the conditions that is also pathogeny fungus of tobacco,which will further study in future.

结论］ 分离的这2株肠杆菌属的内生细菌在一定条件下会导致烟草发病，也是烟草的病原菌，这需更深入的进行研究。

The most convenient and effective method among the three methods of isolatingUstilaginodea virens was the vibrating method. XBZ medium was the best method toget chlamydospores through screening for the six media. Based on chlamydosporesthrough vibrating cultured in PS liquid on shaking bed at 130r/min under 26℃darkconditions for 7 days, conidia were largely obtained. Occurrence information of rice false smut on paddy at Hengnan in 2006 wasinvestigated.

稻曲病病原菌用3种方法分离，结果比较得出振落法最方便有效；通过对6种培养基的比较筛选，结果表明胁本哲氏培养基能快速的产生大量的厚垣孢子；把厚垣孢子放在PS培养液于水平摇床上26℃黑暗条件下130r／min振荡培养，能在7d产生大量分生孢子。

The pathogen of gas gangrene mainly exist and live in local place, and seldom enter blood system to cause blood poisoning, but than can form lots of toxins, this toxins can harm blood system, kidney system, and also the tissue can putrescence and the wound will enlarge step by step, all tissue putrescence and toxin can make these bacteria easier to live and reproduce, all these situation if not being control in time will lead a serious situation that multiple organs dysfunction and then died

气性坏疽的病原菌主要在伤口内生长繁殖很少侵入血液循环引起败血症。产气夹膜杆菌产生α毒素、胶原酶透明质酸酶、溶纤维酶和脱氧核糖核酸酶等，红细胞破坏引起溶血血红蛋白尿、尿少、肾组织坏死水肿、液化，肌肉大片坏死使病变迅速扩散、恶化。糖类分解产生大量气体使组织膨胀；蛋白质的分解和明胶的液化，产生硫化氢，使伤口发生恶臭由于局部缺血，血浆渗出，及各种毒素的作用伤口内的组织和肌肉，进一步坏死和腐化，更利于细菌的繁殖使病变更为恶化。
