How are Pathogenic Bacterial Infections Diagnosed Histologically?
Diagnosis often involves staining techniques to identify bacteria and assess tissue changes. Common stains include Gram stain, which differentiates bacteria into gram-positive and gram-negative, and Ziehl-Neelsen stain for acid-fast bacteria like Mycobacterium tuberculosis. Immunohistochemistry may also be used to identify specific bacterial antigens within tissues.
