为查明广西武鸣县某养殖场患腹水病黄颡鱼的病原菌及其敏感药物,以常规方法进行细菌分离,人工感染试验确定病原菌的致病性,API 20NE进行细菌鉴定,K-B纸片扩散法进行药敏试验。试验结果,从患病濒死黄颡鱼的心脏和肝脏分离到3株病原菌类志贺邻单胞菌(Plesiomonas shigelloides),3株病原菌对先锋VI、菌必治、舒普深等16种药物都高度敏感,对青霉素G和氨苄青霉素都不敏感。
In order to identify pathogenic bacteria and their sensitive drugs of Aspergillus catfish with a disease of ascites in a farms in Wuming County, Guangxi, bacterial isolation was carried out by routine methods and pathogenicity was determined by artificial infection test. API 20NE was used for bacterial identification and KB disk diffusion Act for susceptibility testing. The results showed that three pathogens, Plesiomonas shigelloides, were isolated from the heart and liver of the moribund yellow catfish, and three pathogens were isolated from 16 drugs such as Vanguard VI, Are highly sensitive to penicillin G and ampicillin are not sensitive.
