Most eumycetoma is caused by M. mycetomatis, whereas most actinomycetoma is caused by N. brasiliensis, S. somaliensis, A. madurae, and Actinomadura pelletieri. People who develop mycetoma likely have a weakened immune system. It can take between 3 months to 50 years from the time of infection to first seeking healthcare advice.
