Dark-field microscopy is routinely used to detect spirochetes in skin lesions in early syphilis. This type of microscopy uses a specialized condenser to illuminate the specimen with light from the side, which allows the spirochetes to stand out against a dark background. Bright-field and phase-contrast microscopy are not commonly used for syphilis diagnosis, and DNA fingerprinting is typically reserved for more complex analyses of bacterial strains.
