Why Is the Study of Antimicrobial (Drug) Resistance a Priority for NIAID?
Over time, many infectious organisms have adapted to the drugs designed to kill them, making the products less effective. Because most bacteria, viruses, and other microbes multiply rapidly, they can quickly evolve and develop resistance to antimicrobial drugs.
ANALYSIS OF STAPHYLOCOCCUS SP. FOR SECONDARY METABOLITE PRODUCTION Dr. Nazia Jamil1 and Nuzhat Ahmed2 1Department of Microbiology and Molecular Genetics, University of Punjab, Lahore, Pakistan 2Centre for Molecular Genetics, University of Karachi, Karachi, Pakistan.
