早春季节罗非鱼源嗜水气单胞菌的分离鉴定

Abstract

Abstract: In early spring 2012, a disease outbreak occurred at a tilapia farm in Liuzhou of Guangxi province. A gram-negative bacillus was isolated from liver,kidney and spleen of infected tilapia. The isolate was identified as Aeromonas hydrophila by biochemical assays and 16S rDNA sequencing. Healthy tilapia injected with 1×10⁹ CFU of the isolate reached a mortality of 100% in just 24 h. Drug sensitivity experiment showed that the isolate was only resistant to ampicillin and sensitive to 15 types of antibiotics such as aztreonam,ofloxacin,etc. This study provided a basis for the prevention and control of tilapia diseases in early spring.

Key words: tilapia; Aeromonas hydrophila; strong virulence; early spring

CLC Number:

S816.79
