IL17A and eumycotic mycetoma: In the current study we demonstrated that also the Th17 signature cytokine, IL-17A was expressed in the mycetoma granuloma of different mycetoma causative agents including M. mycetomatis, S. somaliensis and A. pelletieri. In eumycetoma caused by M. mycetomatis it was found to be mainly expressed in zones I and II, lower expression was noted in zone III.
