In Vitro Susceptibility of Commonly Used Antibiotics against Vibrio Parahaemolyticus, Isolated From Fin Fishes, Chennai, India

The main aim of this study is to work out the antibiotic profile of true bacteria parahaemolyticus isolated from fin fishes collected from 3 major fish landing sites in urban center, India. a complete of 112 fin fish samples were screened for gram-negative halophilic microorganism V.parahaemolyticus that enclosed thirty of Red snapper (Lutjanus campechenus), forty of Indian sardine (Sardinella longiceps) and forty two of Rohu (Labeo Rohita) on the skin surface was compared exploitation normally used antibiotics. Thirty 2 samples were found to be positive. To find the pathogenicity of the known isolates Kanagawa reaction was performed. Among thirty two isolates, five were found to be positive for Kanagawa reaction. The in vitro status of V.parahaemolyticus was studied by disk diffusion methodology exploitation disks contained antibiotic drug, Ofloxacin, Cefazolin, Clindamycin, Gentamycin and antibiotic. The isolated V.parahaemolyticus strains showed high degree of sensitive to antibiotic drug and Ofloxacin.
