of infection that might be caused by the microorganisms being studied. This laboratory does not require the use of virulent human pathogens. However‚ many types of microorganisms are potentially pathogenic. This means that‚ although they would not cause disease in a normal healthy host‚ they might possibly do so if a large enough quantity of the microbes came into contact with a compromised host‚ such as by wounds and cuts. In addition to microorganisms‚ there are some chemicals used in this laboratory

RESEARCH PAPER ON BIOLOGICAL ACTIVITY OF ACTINOMYCETES ................ ABSTRACT: The microorganisms are ubiquitous in nature. They are found in probably every environmental condition present on earth. Actinomycetes were originally considered to be an intermediate group between bacteria and fungi but now are recognized as prokaryotic organisms with high G+C (>55%) content in their DNA. Our project aim is to evaluate some biological activities of Actinomycetes like:
