摘要
从汕头地区5个养鳗场的患赤鳍病的病鳗中均分离到病原菌是嗜水气单胞菌(Aeromonas hydrophila(chester)stanler),将有毒力的87株病原菌对养鰻场常用抗菌剂进行耐药性试验,结果表明,4种抗菌剂的MIC、MIC_(50)和耐药率分别是:土霉素109.3μg/ml、50.0μg/ml和78.8％;氯霉素123.3μg/ml、63.0μg/ml和90.7％;复方磺胺甲基(口恶)唑(TMP/SMZ)720/3600μg/ml、126/630μg/ml和42.5％;痢特灵79.7μg/ml、63.0μg/ml和65.5％。4种被测抗菌剂的平均MIG分别是对照敏感菌株的109.3,102.7,72和26.6倍。
Pathogens were isolated from 25 eels suffering from red fin disease in the culture ponds of five eel farms. The isolated pathogen was proved to be Aeromonas hydrophila. Eighty seven strains were tested against oxytetracyclin, chloamphenicol, trimthoprim-sulfamethoxazole (TMP/SMZ) and furazolidone respectively to determine the MIC. The results showed high degrees of resistance of the pathogen to the four antimicrobial agents tested. The aferage MIC, MIC_(50) and percentage of resistant strains for oxytetracyclin were 109.3μg/ml, 50μg/ml and 78.8% respecttively; those for chloamphenical were 123.2μg/ml, 63.0μg/ml and 90.7% respectively; those for TMP/SMZ were 720/3600μg/ml, 126/630μg/ml and 42.5% respectively: and those for furazolidone were 79.7μg/ml, 63.0μg/ml and 65.5% respectively. The average MIC for the four antimicrobiol agents were 109.3, 102.7 and 26.6 times respectively the MIC of the sensitive control strains.
