Light and scanning electron microscopy of Stellantchasmus sp (Trematoda : Heterophyidae).
Southeast Asian J Trop Med Public Health. 1997; 28 Suppl 1:213-6.SA

Abstract

Light and scanning electron microscopy of heterophyid fluke, Stellantchasmus sp were studied. The adults were obtained from Rattus norvegicus, 7 days after experimental infections with the metacercariae from the body cavity of Dermogenus pusillus. Living specimens and stained flukes were examined by light microscope. The present worm differed from S. batillans having a single testis while testes of S. gallinte were tandam. It is closed to S. falcatus and S. aspinosus but can not be identified to species because of acetabular spines. The tegumental surface by SEM was investigated on encysted metacercariae and adults. It was nearly smooth with one end shallow wide groove of the metacercarial surface. The entire surface of adult worms were almost covered with scale-like spines, pectinate, 7-9 teeth. The size of scale was largest in the middle of body and decreased both anterior and posterior. No spines were around the excretory pore but has a wrinkled surface appearance. The dorsal surface appeared to have scale-like spines and pectination on the ventral surface. The papillae consisted of a single club-like cilium, solitary or grouped on the anterior part of the body especially anterior of oral sucker. Acetabulum located slightly right of the middle and invagination.
