Abstract:  Water, methanol and acetone extracts of polychaete Perinereis cultrifera were screened for their antibacterial and antifungal activities. Extracts were obtained from the whole body tissue of the animals and tested against 10 different pathogenic bacteria and 4 pathogenic fungi. Fractionated extracts of acetone (A), methanol (M) and acetone with methanol prepared in different concentrations such as 1, 5, 25, 50,100, 200, mg/l were also tested against bacterial pathogens. Among the extracts, methanol showed maximum antibacterial activity against Staphylococcus aureus (8.0 mm) and minimum against Klebsiella oxytoca (1.0 mm) both in methanol and acetone extracts. As regards antifungal pathogens, methanol extract showed maximum activity against Rhizopus sp. (12.0mm) and minimum against Aspergillus niger (2.0mm) in the water extract. Trace activity was noticed against Mucor spp. and A. niger in water and acetone extracts respectively.
