562STUDY OF ANTIBACTERIAL PROPERTIES IN COELOMIC FLUID FROM THE EARTHWORM EUTYPHOEUSGAMMIEI (BEDDARD)Eutyphoeus gammiei (Beddard) is an endemic, large earthworm of Tripura,( a north-eastern state of India) which is found within 15-30 cm of soil. A study on this earthworm’s coelomic fluid with regard to antibacterial property was carried out for the first time. Earthworms were collected by hand sorting and digging technique and cultured in laboratory. Coelomic fluid was collected by electrical stimulus and used against six types of bacteria.Out of six bacteria used in the experiment, coelomic fluid of Eutyphoeus gammiei showed antibacterial activity against E.coli, L.acidophilus, and little activity against P.aeruginosa and no antibacterial activity against Proteus vulgaris, Bacillus subtilis and Staphylococcus aureusdrbhattacharjeegautam@gmail.comResearch612015Antibacterial activity, Coelomic fluid,Earthworm,EutyphoeusgammieiGautam Bhattacharjee,Atish Chandra GhoshAssistant Professor, Department of Zoology, Government Degree College, Dharmanagar, North Tripura, India.,Assistant Professor, Department of Botany, Government Degree College, Dharmanagar, North Tripura, India
