Determination of Antibacterial Activity of Marine Puffer Fish Arothron Immaculatus Collected From Thoothukudi Coast

Abstract

The antibacterial activity of crude acetic acid extracts of puffer fish Arothron immaculatus against ten bacterial strains has been evaluated. Skin, liver, muscle, intestine and ovary extracts of Arothron immaculatus prepared by using acetic acid. The antibacterial test was performed by Agar diffusion technique. The ovary extract showed maximum activity with zone of inhibition with 14.0 mm radius at 10mg/10µl in Shigella flexneri                       and the muscle extract showed minimum zone of inhibition with 6.0 mm radius at 10mg /10µl in Pseudomonas sp. The antibacterial activity of tissue extracts of Arothron immaculatus was compared with the standard antibiotics like Malachite green, Penicillin and Streptomycin. The results indicated that the Skin, liver, muscle, intestine and ovary tissue extracts of Arothron immaculatus may have potent antibacterial compounds that can be further explored and utilized for the welfare of mankind.
