What Histological Techniques are Used to Identify Pathogens?
Several histological techniques are employed to identify pathogens:
- Staining Methods: Techniques like Gram staining and Ziehl-Neelsen staining help identify bacterial species. - Immunohistochemistry (IHC): Uses antibodies to detect specific antigens in tissues, useful for identifying viral and some bacterial infections. - In Situ Hybridization (ISH): Detects specific nucleic acid sequences, helpful for identifying viral DNA or RNA within tissues.
