Antimicrobial activity of the Coelomic fluid of Earthworm against disease causing bacteria: Investigation of Antimicrobial Effects of Eisenia fetida Coelomic Fluid on Disease-Causing Bacteria

Abstract

Earthworms are first annulated eucoelomate organism having complete digestive system,closed circulatory system with haemoglobin in the plasma to carry oxygen and carbon di oxide. Manybiological activities are shown by the coelomic fluid of the earthworm Eisenia fetida.e A study was made tomonitor antimicrobial effect of the coelomic fluid using the zone of inhibition technique against bacterialstrains of Pseudomonas aeruginosa, Staphylococcus aureus, Shigella flexneri, Enterococcus faecalis. Thebest inhibitory effect of Eisenia fetida coelomic fluid on the growth of Shigella flexneri observed was 12mmand that on Staphylococcus aureus was 9mm and on Enterococcus faecalis was 7mm, whereas the zone ofinhibition observed was minimum 3mm against Pseudomonas aeruginosa.
