Comparison of Antibacterial Activities of Coelomic Fluid of local Species of Earthworms of Gulbarga.

Dr Shankerappa S. Hatti

Abstract :

 Coelomic fluid of earthworm is  having bactericidal activity. It was our interest to know the bactericidal activity of the coelomic fluid of Polypheretima elongata,Perionyx sansibaricus and Dichogaster bolaui against pathogenic bacteria like Escherichia coli, Staphylococcus aureus, Pseudomonas, Proteus, and Bacillus. Polypheretima elongata, Perionyx sansibaricus and Dichogaster bolaui are local species of earthworms present in Gulbarga. Bactericidal activity coelomic fluid of the earthworm was tested among the three species and in comprision with the commercial antibiotics available in the market. The batricidal activity of the coelomic fliud of the earthworm was determined by the zone of inhibition by coelomic fluid of earthworm Polypheretima elongata, Perionyx sansibaricus and Dichogaster bolaui against pathogenic bacterial strains. Our results show that the zone of inhibition varies from species to species, and it is species specific to particular bacteria. It is clear that antibacterial activity is exhibited at different levels by coelomic fluid of Polypheretima elongata,Perionyx sansibaricus and Dichogaster bolaui.The coelomic fliud of Polypheretima elongata exhibited highest bactericidal activity against Escherichia coli and Staphylococcus aureus. Perionyx sansibaricus has highest bactericidal activity against Proteus and Pseudomonas.Dichogaster bolaui against Stphylococcus aureus and Bacillus
