IDENTIFIKASI PARASIT Clinostomum sp. (TREMATODA) PADA IKAN SEPAT (Trichogaster trichopterus) DENGAN SCANNING ELECTRON MICROSCOPE

Abstract

A study on identification of Clinostomum infections in Trichogaster trichopterus in Pekanbaru has been conducted on August to October 2011. This study aims to understand the topography of Clinostomum in Trichogaster trichopterus. Excysted Clinostomum sp. was found in cavity organ were aseptically taken using needle, preserved in absolute ethanol. Morphological examination was done with Scanning Electron Microscopy (SEM). Result shown that topography of the tegument of Clinostomum sp. metacercariae infections in Trichogaster trichopterus in Pekanbaru indicated different structure in individual surface. Oral sucker located at the subterminal end, ellips and was surrounded by fine surface pucker. The ventral sucker was close to oral sucker toward anterior area, and had round sensory papillae without spinae. The body surface was concave without spinae and was completed with round papillae. Round and pucker-surrounded excretory pore appeared at the posterior terminal. Results of Scanning Electron Microscopy indicates that Clinostomum sp. identified in this study was similar to Clinostomum cutaneum.
