我国淡水鱼类柱形病病原菌柱状黄杆菌的遗传多样性 [PDF]

open access: yes, 2010
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 ...

A pilot study of antimicrobial effects and ototoxicity of a Norway spruce (Picea abies) resin‐based canine otic rinse product

open access: yesVeterinary Dermatology, Volume 35, Issue 3, Page 325-336, June 2024.
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.

石首地区野生麋鹿自然保护区重要病原菌(虫)调查

open access: yes野生动物学报, 2018
为了调查石首麋鹿自然保护区内重要病原菌和寄生虫的感染情况,通过麋鹿粪便和脏器进行细菌分离培养及16S rRNA PCR等方法对病原菌进行鉴定; 通过饱和食盐水漂浮法和沉淀聚集法对麋鹿粪便中的寄生虫卵进行检测。结果显示:从麋鹿粪便及病死麋鹿病料中共分离出8种菌,其中粪肠球菌、乳酸杆菌、大肠杆菌为肠道正常菌群,嗜水气单胞菌为条件致病菌,而志贺杆菌、蜡样芽孢杆菌、产气荚膜梭菌和链球菌均为重要病原菌,可导致麋鹿腹泻、败血症甚至引起死亡。从麋鹿粪便中共检测出3种虫卵,分别为前后盘吸虫卵 ...

ヤサイルイ ナンプビョウ サイキン ノ ファージガタ ノ ヘンドウ ニ カンスル ケンキュウ [PDF]

open access: yes, 1996
【緒言】野菜類軟腐病細菌Erwinia carotvora subsup.carotovoraのファージは系統特異性であり,ファージ感受性の差異によって本病原菌はいくつかのファージ型(溶菌型)に類別される8.9)前報では宿主範囲の異なる10系統のファージを用いて鶴岡市周辺のハクサイ栽培ほ場で軟腐病菌のファージ型の分布を調査し,ファージ感受性菌の割合や優占的に分離されるファージ型が年次的に変動することを明らかにした.しかし,このようなファージ型の存在の植物病理学的意義,役割等については殆ど検討されていない.
