How are Microorganisms Identified in Histological Samples?
Identification of microorganisms in histological samples typically involves special staining techniques and microscopic examination. Common stains include the Gram stain for bacteria, the Giemsa stain for parasites, and the Periodic Acid-Schiff (PAS) stain for fungi. Advanced techniques such as immunohistochemistry and in situ hybridization are also employed to detect specific microbial antigens or genetic material within tissue sections.
