This branch of pathology focuses on the identification and diagnosis of diseases caused by infectious agents such as bacteria, viruses, fungi, and parasites. Pathologists in this field work closely with microbiologists to analyze tissue biopsy specimens, cultures, and molecular tests to diagnose infections such as tuberculosis, fungal infections, viral hepatitis, and conditions such as sepsis. Accurate identification of the pathogen is critical for selecting appropriate antimicrobial therapy and managing infectious disease outbreaks.
