The present study shows the antibacterial activity of acetonitrile, methanol, dichloromethane and ethanol extracts of Astropecten indicus against ten selected clinical pathogenic bacterial isolates. All the bacterial strains selected for the experiment are well known for their ability to infect the human urinary tract. The present investigation showed that the extracts of starfish A. indicus have moderate inhibitory effects against the clinical isolates at the higher concentration (1000µg/ml), whereas lower inhibitions were recorded at the median concentration (500µg/ml) and lower concentration (250µg/ml) of all the extracts were not enough to inhibit the growth of any bacterial pathogens. Among the four different extracts, acetonitrile extracts showed higher inhibitory effect against the gram positive Staphylococcus aureus (4.2±0.14) and Mycoplasma genitalium (3.7±0.23) at higher concentration.
