The gram negative bacteriam Aeromonas hydrophila is a common cause of different diseases of fish in Thailand. The most serious disease caused by this organism is ulcer disease in catfish (Clarias batrachus). One hundred and eight strains of A. hydrophila were isolated in May 1976 to March 1978. All tested strains were sensitive to Kanamycin, 1 percent resistance to nitrofurantein and polymyxin B, 5% to neomycin, 8% to chloramphenicol, 9% to tetracyclin, 13% to trimethoprim, 15% toerythromycin, 40% to sulfamethoxine and sulfathiazole, 45% to streptomycin, 46% to sulfamerazine, 52% to sulfadiazine, 97% to penicillin. The results indicated that the local isolated strains are more resistant to antimicrobial agents than the Danish strains.
