从日本各地区养殖鱼类和甲鱼（Trionyx sinensis）中分离的72株嗜水气单胞菌耐药菌株中，39株携带可转移耐药因子。鱼类包括鳗鱼（日本鳗鲡）、鲤鱼（鲤鱼）、香鱼（香鱼）和金鱼（鲫鱼）。抗性因子以磺胺类和四环素类的抗性标记最多，均为thefi型。12株A.从野生鳗鱼中分离出来的。A.从养殖鱼类中产生的化疗药物被认为是由于鱼类养殖中使用的化疗药物所施加的选择性压力。
Thirty-nine out of 72 drug-resistant strains ofAeromonas liquefaciensisolated from cultured fish and soft-shelled turtles (Trionyx sinensis japonicus) in various districts of Japan carried transferable drug resistance factors. The fish included eel (Anguilla japonica), carp (Cyprinus carpio), ayu (Plecoglossus altivelis) and goldfish (Carassius auratus). The most common type of resistance factors had the markers of resistance to sulphanilamide and tetracycline and all belonged to thefi-type. Transferable drug resistance was not found in any of 12 strains ofA. liquefaciensisolated from wild eels. The high incidence of resistance factors inA. liquefaciensfrom cultured fish is assumed to be due to the selective pressure exerted by chemotherapeutics used in fish culturing.
