为了鉴定乌苏里母貉腹泻性疾病病原,采集患腹泻母貉的肛拭子及粪便样品,通过胶体金试纸条、卵囊分离法、PCR法和细菌分离鉴定等方法对采集的病料进行病原检测。结果显示,犬瘟热病毒、细小病毒、冠状病毒抗原检测为阴性,分离鉴定的病原为钩口线虫和大肠杆菌,通过致病性试验验证其致病性,分离的大肠杆菌对小白鼠具有很强的致病性。引起貉腹泻的病原为钩口线虫和大肠杆菌混合感染,且分离的致病性大肠杆菌对头孢曲松、头孢噻呋、美罗培南、左氧氟沙星4种药物敏感,其他的药物具有不同的耐药性。为貉腹泻病的防控提供研究基础。

Functional analysis of plant immune regulator OsPti1a in rice [PDF]
An understanding of plant immune systems is important for crop breeding with enhanced disease resistance against pathogen infection. Previous studies reveal that plant has evolved two types of defense mechanisms, which are called “basal resistance” and “

The inhibiting effect of 357 bacteria and its antagonistic substance against powdery mildews
浙江大学生物技术研究所从杭州郊区的茄子叶表面分离到了一株Bacilus cereus(命名为357细菌).它对多种植物病原细菌和植物病原真菌具有较强的拮抗效果.本文报道357细菌菌液及其分泌的拮抗物质对麦类白粉病菌的抑制作用.

Abstract The preservation of the culturally important traditional herbal medicine practice in Ghana is threatened by the growth of allopathic medicine. It is argued that two main factors comprise this threat: significant safety concerns over many traditional herbal preparations, and a conflict in therapeutic frameworks which provides a substrate for ...

为认识我国淡水鱼类烂鳃病的病原以及柱形病在我国的发生情况,实验从发生烂鳃病的病鱼中分离细菌性病原,经过生理生化特性分析以及是否在含托普霉素的Shieh培养基中生长并形成黄色假根状菌落,是否产生降解明胶和硫酸软骨素的酶类等特性的鉴定,并结合16SrDNA序列分析,证实柱状黄杆菌(Flavobacterium columnare)是所分离的烂鳃病的病原。同时,研究也证实20世纪曾经命名为烂鳃(Gill-rot)病病原的鱼害黏球菌(Myxococcus piscicola Lu,Nie & Ko,1975 ...

Background – Norway spruce (Picea abies) resin‐based products are used in human medicine. A resin‐based otic rinse also could be useful in supportive care of canine otitis externa (COE), yet information on its antimicrobial effect against canine pathogens or ototoxicity is lacking.

Structure and function of Streptococcus mutans VicK [PDF]
双组分系统TCS包括感受外界刺激信号的组氨酸激酶HK和调控基因转录的应答调节蛋白RR,是许多病原菌应对外界环境变化的主要调节系统。HK能感受如温度、氧浓度、渗透压、pH、菌浓度、抗生素等条件的变化,并对下游的RR进行磷酸化。被磷酸化激活的RR,有60%可以行使转录因子的功能,对相应的基因进行调控,从而使致病菌在压力环境下的生存能力大大增强。 TCS存在于几乎所有的病原菌中,但却未在动物和人类中发现,这使得针对TCS进行药物设计成为一个非常热门的领域。目前,已经开发了很多针对TCS的小分子抑制剂 ...
