How are Pathogens Detected in Histological Samples?
Different staining techniques and microscopic methods are employed to detect pathogens in histological samples. Commonly used stains include Gram stain for bacteria, Giemsa stain for parasites, and Periodic Acid-Schiff (PAS) stain for fungi. Additionally, special immunohistochemical stains can target specific antigens associated with various pathogens.
