영문 초록

The Aeromonas strains were isolated from diseased cultured catfsh(Silurus asotous) in the ponds near by Gochang of Chunbuk. The present isolates were identified as A. hydrophila based on their biological aud biochemical characteristics. The isolates of A. Hydrophila were named GC-l, GC-2, GC-3, GC-4 and GC-5. Five strains were grew optimally at temperatures 35℃. pH 7.5 and in 0.5 to 1% NaCㅣ, This bacterium(GC-l) was injected into health catfish in order to prove the causative agent of ascites and haemorrhagic ulcers. The symptoms in catfish infected by this challenge method were observed to be very similar to the symptoms of a natural infection, but controls did not show any abnormal symptoms during the experimental period. At 24 post-injection, the red spot developed around the injection site and the haemorrhagic ulcers was extended near the gill and ventral fin. Five strains were tested for drug sensitivity by plate method. All strains were sensitivity to gentamicin and resistant to penicillin, streptomycin and tetracycline.
