Abstract

A total of 1000 cultured Nile-tilapia (Oreochromis niloticus) were collected from different governmental and private fish farms and examined for detection of myxosporean parasites infection. The infected fish showed slight unilateral exophthalmia with whitish cyst in the eye. Numerous white cyst like plasmodia of Myxobolus dermatobius were recovered from the eye of the examined fish with low prevalence rate (1%). Small intact cyst was isolated, fixed in 3% glutaraldehyde in 0.1 M sodium cacodylate (pH 7.4) and prepared for electron microscopy examination. Ultrathin sections of Myxobolus dermatobius spore revealed pair of capsulogenic cells at the apical pole of the developing spore.
