Abstract

The SEM study on morphology and surface topography of Wenyonia minuta was undertaken.The parasite was recovered from the intestine of Synodontis filamentosus. A total of two hundred and forty five specimens of the fish host were examined.The female specimens (n =88) has a prevalence of 69.3% while the male specimens (n = 157) had a lower prevalence of 46.4%. The SEM description of the caryophyllidea cestode revealed the scolex to be fluke – like with four shallow longitudinal groove and flat pointed anterior end. The overall length of the scolex is 104250.97µm with a breadth of 653451.20µm.The furrow longitudinal groove were only observed on the dorsal side of the scolex. External protuberances were also reported in this study. The histopathological analysis shows matting, lymphocytic infiltration of the lamina propria, goblet cell hyperplasia while some sections with no significant pathological changes were also observed.
