Antibiotic Resistance in Micrococcus SP Isolated from Freshwater Fish Farms Catla Catla

Abstract

Freshwater and marine fish are affected by very few pathogens, in specific flexibacteria, aeromonads and vibrios, several pathogens may present as only skin infections. Ulcer, hemorrhage, scale reduction, tail and fin rot, dropsy involves many bacterial diseases, is present in fishes.  Ten bacterial genera were isolated, where these fish pathogens belonging to Micrococcus sp., Bacillus sp., Aeromonas sp., Flavobacterium sp., Staphylococcus sp., Enterobacteria sp., E. coli, Pseudomonas sp, Salmonella sp., Shigella sp., associated with Catla catla. These pathogen isolated from freshwater fish Catla catla were characterized the pathogen as being susceptible to antibiotics such as Amoxycillin, Azithromycin, Cefixime, Ciprofloxacin, Chloramphenicol, Furadantin, Gentamicin, Levofloxacin, Tetracycline and Vancomycin. The present study reports the results of inhibition of pathogen by Amoxycillin and Azithromycin.
