Abstract

Some species of mesophilic bacteria in the genus Aeromonas were isolated from a snakehead (Channa argus) culture-pond in the Myung-Ji area, a freshwater culture-pond in Pukyung National University, and seawater near the sewage treatment plant in Kwang-An Beach in Pusan. They were identified by biological characteristics, and their susceptibility to ten antibiotics including ampicillin, cefoxitin, ceftazidime cephalothin, cefotiam, chloramphenicol, nalidixic acid, rifampin, cefoperazone-sulbactam, and imipenem, was also studied. Four species in the genus Aeromonas, A. veronii biovar sobria (27 strains), A. caviae (14 strains), A. trota (1 strain), and A. schubertii (1 strain) were identified. A. trota, an unrecorded species in Korea, is reported for the first time in this study. Three strains of A. veronii biovar sobria showed multiple resistance to three kinds of antibiotics and one strain to four drugs. All strains of A. caviae were resistant to more than three drugs and seven strains to four drugs. A. trota was resistant to cephalothin and rifampin, but A. schubertii showed multiple resistance to ampicillin, nalidixic acid, and rifampin.
