摘要: 试验旨在鉴定吉林省某雏鸡孵育基地病死雏鸡组织中分离出的1株致病性菌CCGGD201101株并测定其致病性。对疑似致病菌进行生理生化试验、16S rDNA测序鉴定,并人工接种昆明鼠,测定其半数致死量,验证细菌毒力。经鉴定该菌为鲍曼不动杆菌(Acinetobacter baumannii)。以鲍曼不动杆菌CCGGD201101分离株为研究对象,并以鲍曼不动杆菌标准株(ATCC 19606)为对照,测得半数致死量,进一步证明鲍曼不动杆菌病死鸡分离株CCGGD201101具有较强致病性。

Abstract: The study was aimed to identify the virulent strain CCGGD201101 isolated from dead chicks of a chick farm in Jilin province and determine its pathogenicity. The suspected pathogens were identified by means of physiological and biochemical tests and 16S rDNA sequencing. The median lethal dose to Kunming mice was determined to verify bacterial virulence.The results showed that this strain was Acinetobacter baumannii. The half lethal dose was determined with Acinetobacter baumannii CCGGD201101 as target while Acinetobacter baumannii standard strain (ATCC 19606) as control. The pathogenicity of Acinetobacter baumannii strain CCGGD201101 was further confirmed.
