中华草龟源维氏气单胞菌的分离及生物学特性鉴定

open access: yes野生动物学报, 2022
为了确定引起中华草龟(Chinemys reevesiis)死亡的病原菌并鉴定其生物学特性,从病死中华草龟病变肝脏组织分离得到1株病原菌,经生化鉴定,其为维氏气单胞菌(Aeromonas veronii),命名为CRQ1。采用斑马鱼(Brachydanio rerio)攻毒试验进行了该分离菌的致病性检验; 采用PCR方法检测了该分离菌携带的毒力基因及耐药基因; 采用K-B药敏纸片法检测其耐药性。结果显示:CRQ1株对斑马鱼的半数致死量( LD50)为3.57×107cfu/mL,携带aerA、act ...
