Scanning and transmission electronmicroscopy of Mekong Schistosoma eggs and adults.
Eggs and adult males and females of Mekong Schistosoma were studied by scanning and transmission electronmicroscopy. The observation of the eggs by the scanning and light microscopy revealed fine shell fenestration and a prominent knoblike spine. There are marked differences between the surface structures of male and female as studied by scanning and transmission electronmicroscopy. The surface of the male schistosome is moderately rough while that of the female is relatively smooth. SEM reveals certain basic features such as spines in the oral sucker, minute spines and folds in the gynecophoral canal of the male, and general features of male and female tegumental surfaces. The observations of the cross sections of adult schistosomes by transmission technique revealed certain features such as spines or ridges, and mucin droplets on the surface, the smooth muscles lining the integument, the mucin-producing cells and numerous lipid droplets in the body of the Schistosoma.
