Medical Microbiology is the study of microorganisms, including bacteria, viruses, fungi, and parasites, in relation to diseases in humans. It involves the identification, diagnosis, and treatment of infectious diseases, as well as studying the mechanisms of infectious agents and the immune system's response to them. Medical microbiologists use laboratory techniques to identify and characterize microorganisms, interpret diagnostic test results, and develop treatment plans. They work closely with clinical practitioners and public health professionals to ensure the prevention and control of infectious diseases.
