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 understand their role in infections and to guide appropriate treatment options. In a clinical setting, Clinical Microbiologists work closely with healthcare professionals to diagnose infections through laboratory tests. They analyze samples from patients, such as blood, urine, and swabs, to detect the presence of harmful microorganisms and determine their susceptibility to antibiotics, which is crucial for effective patient care.
