Abstract: <smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="country-region"><smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="place"> Water, methanol and acetone extracts of polychaete <i style="">Perinereis cultrifera<b style=""> </b></i>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<i style=""> Staphylococcus aureus </i>(8.0 mm)<i style=""> </i>and minimum against <i style="">Klebsiella oxytoca</i> (1.0 mm) both in methanol and acetone extracts. As regards antifungal pathogens, methanol extract showed maximum activity against <i style="">Rhizopus</i> sp. (12.0mm) and minimum against <i style="">Aspergillus niger</i> (2.0mm) in the water extract. Trace activity was noticed against <i style="">Mucor </i>spp. and <i style="">A. niger</i> in water and acetone extracts respectively.</smarttagtype></smarttagtype>
