Pathological understanding of infectious diseases is essential for accurate diagnosis and public health management. This book offers a comprehensive review of infectious agents—bacteria, viruses, fungi, and parasites—and their effects on human tissues. It details host-pathogen interactions, tissue tropism, and immune responses. Each section includes characteristic histopathological findings and diagnostic methods such as staining, culture, and PCR. Key diseases are examined system-wise, from tuberculosis and viral hepatitis to fungal lung infections and protozoal encephalitis. Emphasis is placed on morphological features that help distinguish infections from other pathologies. The resource integrates laboratory science with clinical signs for thorough understanding.
Gwyneth Marks has a background in infectious disease pathology and microbiological diagnostics, with a focus on disease-host interactions. She has co-developed protocols for histopathological identification of viral and bacterial agents in tissue samples. Her research addresses the pathology of emerging infectious diseases and zoonotic infections. She contributes to global health surveillance efforts through her work with research laboratories. Her interests include granulomatous infections, opportunistic pathogens, and pandemic preparedness.
