Effect 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. Indiscriminate uses of antibiotics have caused microbial resistance and also lead side effects. 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 in vitro 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) antibacterial activity is agar disc diffusion technique. A reference standard drug, Amphicillin was used. The results showed good antibacterial activity of cow urine against most of the test bacterial strains by exhibiting zone of inhibition. These results thus proves that indigenous cow urine possess good inhibitory activities against fish pathogens and can be used to control infectious diseases.
