Objective: The study of marine organisms for their bioactive potential, being an important part of\udmarine ecosystem has picked up the rhythm in recent years with the growth recognition of their\udimportance in human life as well as animals. Methods: In this present study ethanol, methanol\udand acetone extract of two gastropods Conus betulinus and Conus inscriptus were assayed for the\udantibacterial activity against three poultry bacterial pathogens. Results: The antibacterial activity\udof Conus betulinus tissue extract, showed maximum zone of inhibition (15mm) against Salmonella\udpullorum and minimum activity (4 mm) was observed in Salmonella typhimurium. In Conus\udinscriptus, the tissue extract showed the maximum zone of inhibition (12mm) against S. enteritidis\udand minimum activity (3 mm) was observed in S. pullorum. Molecular size of muscle protein was\uddetermined using Sodiumdodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). FTIR\udanalysis reveals the presence of bioactive compounds signals at different ranges. Conclusions:\udAmong the two gastropods, Conus betulinus showed more antibacterial activity than that of Conus\udinscriptus. The reveled in this research shows that gastropod Conus betulinus tissue is medicinal\udvalue due to high quality of antibacterial compounds
