Antibiotic and plasmid profiles of Aeromonashydrophila isolated from clinically infected freshwater fishes (Oreochromismossambicus, Puntiusgonionotus, Leptobarbushoevenii, Pangasiuspangasius, Anabas testudineus, Clariasgariepinus and Cichlasoma sp.)

Aeromonashydrophila is one of the most important aquatic pathogen affecting cultured and feral fishes worldwide. Disease infection resulted in million dollar loses to aquaculture. Antibiotic resistance is increasing among pathogenic bacteria due to the extensive and indiscriminate use of antibiotics...
