Quizplus · Accepted Answer

Dark-field microscopy is routinely used to detect spirochetes in skin lesions in early syphilis. It allows for visualization of the spirochetes in a background of low contrast, which enhances their visibility. Bright-field and phase-contrast microscopy may not be as sensitive in detecting spirochetes, and DNA fingerprinting is not commonly used for diagnosis of early syphilis.
