鱼源气单胞菌的主要特性研究

The Main Characteristics of Aeromona Come to Fish

对分离于草鱼肠炎、白鲢鱼打印病、鲢鱼白皮病、草鱼烂鳃、鲤鱼体表出血感染及甲鱼败血症等病例的 80株细菌进行了主要特性研究。结果表明均为气单胞菌属 (Aeromonas)的细菌 ,其中嗜水气单胞菌 (A .hydrophila ) 2 9株 (占 36 .2 5 % )、豚鼠气单胞菌 (A .caviae) 38株 (占 47 5 % )、温和气单胞菌A .sobria ) 13株 (占 16 .2 5 % )。在被检验的病例中 ,或为其中一种气单胞菌的单独感染 ,或为两种、三种气单胞菌的混合感染。经做人工感染试验检查 ,表明这些分离菌均为相应感染症的致病菌。

Studing on the main characteristics to 80 strains bacteria isolated from enteritis of grass carp、putting a seal of silver carp、rotting gill of grass carp、albinism of silver carp、haemorrhage of carp body surface infect and septicaemia of soft_shelled turtle infect.The result showed that all the pathogenic bacteria were identified as the bacteria of Aeromonas,A.hydrophila account for 29 strains(account for 36.25 per cent)、A.caviae account for 38 strains(account for 47.25 per cent)、A.sobria account for 13 strains(account for 16.25 per cent).In all the examined cases,some were infected by one kind of Aeromona,some were jointly infected by two or three kinds of Aeromona.Through examination by experiment of artificial infected,showed that all the isolated bacteria were the pathogenic bacteria of the according infection.
