- Bacterial Culture: Used to identify bacteria responsible for infections. Commonly involves Gram staining and culture on agar plates. - Fungal Culture: Identifies fungal pathogens, often used in cases of ringworm, athlete's foot, or yeast infections. - Viral Culture: Less common but used to detect viral infections, especially in immunocompromised patients. - Molecular Techniques: PCR and other molecular methods can rapidly identify specific pathogens and their antibiotic resistance profiles.
