Diagnosis of Mycetoma
Examination and culture of exudates Causative agents can be identified presumptively by gross and microscopic examination of grains from exudates, which contain pathognomonic, irregularly shaped, variably colored, 0.5- to 2-mm granules. Crushing and culture of these granules provides definitive identification. Exudate specimens may yield multiple bacteria and fungi, some of which are potential causes of superinfections.
