摘　　要：对患败血症的丰产鲫 (Carassiusauratusofpenze (♀ )×Cyprinusacutidorsalis(♂ ) )脾脏中分离到的病原菌—豚鼠气单胞菌 (Aeromonascaviae)CSS 4 2菌株的生长特性进行了研究。CSS 4 2在胰蛋白胨液体培养基中振荡培养时 ,0～ 3h为延迟期 ,3～ 30h为对数生长期 ,30～ 36h为稳定期 ,36h后为裒亡期 ;其最适生长温度为 2 5℃～ 30℃ ,最适pH值为 5～ 1 0 ,最适培养液NaCl浓度为 0～ 1 %。The growth property of pathogenic bacterium Aeromonas caviae strain CSS-4-2 which was isolated from the spleen of Carassius auratus of penze(♀) × Cyprinus acutidorsalis (♂) that diseased septicemia was studied.The growth curve of CSS-4-2:lag phase was in 0～3h,log phase was in 3～30h, stationary phase was in 33～36h,decline phase was after 36h when CSS-4-2 was cultured shaking in tryptone liquid medium. It's optimum growth temperature ranges from 25℃ to 30℃, optimum growth pH ranges from 5 to 10, and optimum salinity ranges from 0% to 1% Nacl concentration .
