A total of 200 adult male Egyptian toads (Bufo regularis) captured from Assiut locality (Upper Egypt), were surveyed for the testicular infection with Myxobolus sp. Ten toads (5%) showed various degrees of infectivity detected by means of light and electron microscopy. The significant pathological changes in the testis were observed. Plasmodia of Myxobolus sp. caused atrophy of the infected testicular tissue. The infection of the seminiferous tubules by the different parasitic stages induced necrobiotic changes in the tubular cells, which suggests the Myxobolus sp. is a pathogenic testicular parasite of the Egyptian toad, B. regularis.
