Clinical microbiology is a branch of medical science that focuses on the study of microorganisms, such as bacteria, viruses, fungi, and parasites, that can cause diseases in humans. It involves the identification and characterization of these pathogens to diagnose infections and guide appropriate treatment. Clinical microbiologists work in laboratories, using various techniques to analyze samples from patients. The field plays a crucial role in public health by monitoring and controlling infectious diseases. It also contributes to the development of new diagnostic tests and treatments. Key areas of study include antibiotic resistance, infection control, and vaccine development.
