Evaluation of antimicrobial activity of indigenous cow urine against bacterial fish pathogens

From the ancient period cow’s urine has been used as a medicine. In India, drinking of cow urine has been practiced for thousands of years. To overcome from such situation plants and animal materials are widely used for the treating various substances due to antimicrobial properties in aquaculture. In Aquaculture, cow urine has been used to improve general health of an individual. Therefore, the present study is under taken to study invitro antibacterial potential of cow urine against fish pathogenic bacteria, like, (Aeromonas hydrophila, Escherishia coli, Bacillus cereus, Pseudomonas aeruginosa and Staphylicoccus aerus) the method employed to study the different concentration of cow urine (25%, 50%, 75% and 100%, control used as distilled water) . MIC was also done to know the minimum inhibitory concentration of cow urine by using U.V. Spectrophotometer. The MIC observed at 100% concentration of cow urine against 5 hour OD value in Bacillus cereus (0.264) followed by P. aeruginosa (1.343), E. coli (1.180), S. aerues (0.776), A. hydrophila (0.740).The present study suggested that, cow urine have great potential as antimicrobial agents against selected fish pathogens and they can be used as an alternative medicine in the treatment or control of fish bacterial infections. From the result it is clear that fresh cow urine has shown very high susceptibility to all bacterial strains at a very low concentration. In the bioassays fresh cow urine exhibited a higher degree of antimicrobial activity in comparison to fresh cow urine and antibiotics. These results indicate that the cow urine has antimicrobial activities, which supports the claim of traditional practionerss.
