摘要：
Toxocara canis is one of the most common helminth worm of dogs which continues to stimulate both public health concern alongside the higher scientific interest. It may cause visceral and ocular damage in humans especially in children. The identification of specific antigens of T. canis is important so as to develop better diagnostic techniques. Excretory-secretory (ES) antigens were prepared by culturing the adult T. canis worms in RPMI 1640 medium without serum supplementation followed by ammonium sulphate precipitation. These antigens were separated using sodium dodecyl sulphate-electrophoresis (SDS-PAGE). Recovered proteins ranged from 30 to 384 kDa. The specific reactivity of the T. canis excretory-secretory (TC-ES) proteins was checked by western blotting. The immuno-reactivity of the naturally infected dog sera with the TC-ES antigens showed five bands at 43, 57,105, 139 and 175 kDa. The immuno-reactivity of the hyper immune serum raised in rabbits against TC-ES antigens was observed with ten polypeptides of 21, 25, 30, 37, 45, 50, 57, 69, 77 and 105 kDa. Common antigens band were observed at 57 and 105 KDa. These antigens merit further evaluation as candidate for use in diagnosis of toxocariasis in humans and adult dogs. © 2012 Indian Society for Parasitology.
