title: A spectrum of antibody response with time after Trichinella spiralis infection in rats.
abstract: A chronology of class-specific antibody response against the Trichinella spiralis infection in Fischer rats was investigated. G-class antibodies against the cuticle inner layer(s), hypodermis, hemolymph, glycogen aggregates, discrete areas in genital primordial cells, intestinal gland cell granules, and cytoplasmic granules in the cords were detectable 2 wk after infection (the rapid-responding group), whereas G-class antibodies against the cuticle surface, stichocyte granules, and the esophagus-occupying substance were detected 6 wk after infection (the slow-responding group). M-class antibodies recognized a narrower spectrum of antigens than did G-class antibodies; M-class antibodies against hemolymph, cord granules, and intestinal gland cell granules were not detectable. M-class antibodies tended to decrease in titer with time after infection. This tendency was more striking with antibodies against the rapid-responding group than with those against the slow-responding group. This information sheds light upon antibody response against many antigenic components of T. spiralis muscle larvae.
