ABSTRACT

During the study period, actinomycetes were isolated from mud wasp nest by serial dilution pour plate method. All the actinomycetes were curtained for their antagonistic proeprties against pathogenic bacterial strains procured from IMTECH, Chandigarh, India. Initially the actinomycetes were primarily screened by cross streak method and only two potential actinomycetes were tested subjected to secondary screening which was done by Agar well diffusion method. Most of the isolates were found active against E. coli, Bacillus subtilis, Staphylococcus aureus, Klebsiella pneumonia and Vibrio cholerae. Most of the actinomycetes (around (80%) showed good antagonistic effect against most of the tested pathogens and 20% of the total actinomycetes were found non-effective against the test pathogens.
