Mycetomas in goats

Naturally occurring mycetomas were found in 3 goats. Two had mycetomas on their hind legs and the third on its left scapula. In 2 goats the causative agents were identified by culture, histopathology and serology as Actinomadura madurae. In the remaining goat diagnosis was based only on histopathology and the causative agent was considered to be A. pelletierii. Despite minor differences between goat and human strains of A. madurae, it would seem that goats could be useful experimental models.
