The antibacterial activities in different solvent extracts of Padina tetrastromatica were screened against human bacterial pathogens Escherichia coli, Pseudomonas aeruginosa, Salmonella typhi, Staphylococcus epidermis and Streptococcus pyogenes. The maximum zone of inhibition was 14mm recorded from methanol extract of Padina tetrastromatica against Escherichia coli and minimum zone of inhibition was 6mm in acetone extract against Staphylococcus epidermis. The minimum inhibitory concentration (MIC) value of Padina tetrastromatica against bacteria was ranged between 0.2±0.1mm (0.1 mg/ml) to 2.2±0.2mm (6.00 mg/ml)
