This research aims to determine the resistance status of various antibiotic classes in <em>A. hydrophila</em> bacteria isolated from African catfish. Bacterial isolates of <em>A. hydrophila</em> were taken from the liver and kidneys of infected African catfishes obtained from Parung, Bogor. Characterization of the bacteria was carried out based on colony morphology and biochemical properties. Meanwhile, bacterial resistance test was conducted using antibiotic disks with Kirby-Bauer method. Based on colony morphology and biochemical properties, the characterization results indicated that the bacterial isolates tested were <em>A. hydrophila</em>. Further examination of the antibiotic resistance test showed that the bacteria were resistant to penicillin antibiotics and macrolides. Future researches are expected to use molecular identification for <em>A.hydrophila</em> bacteria mutant to known the DNA base. </p> ER -
