AB  - A total of 1000 cultured Nile-tilapia
(<i>Oreochromis niloticus</i>) 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.
