Antibacterial susceptibility profiles of alum were determined against bacteria isolated from shellfish bivalve oysters. In-vitro bioassay using disc and agar well diffusion techniques with different concentrations; , , and of Alum were used to determine the susceptibility profiles of these isolates and compared with standard antibiotic, Ofloxacin (OFL) as control. Diameter of inhibition zones (DIZ) also were determined by measuring with a meter rule. | Susceptibility profiles of alum on bacteria isolated from shellfish bivalve oyster
