It showed a complex mixture of at least 37 bands when resolved with the discontinuous buffer system of Laemmli in a gradient SDS-PAGE. Western blot analysis of 16 sera from N. brasiliensis-infected individuals always showed the recognition of six bands of 61, 49, 45, 42, 26, and 24 kilodaltons (kDa). Some other bands also reacted but with less intensity. Sera from tuberculosis and leprosy patients reacted strongly with the 49, 45, and 42 kDa bands but weakly or not at all with the 61, 26, and 24 kDa. Sera from healthy control volunteers reacted with some bands but little or not at all with those three identified by the sera from mycetoma patients. These three immunodominant antigens (61, 26 and 24 kDa) may be of clinical value in the serodiagnosis of mycetoma by N. brasiliensis.</p>  a0934-8840
