title: [Antigenic recognition of rats infected with Gnathostoma hispidum: comparison of antigens derived from the advanced third stage larvae of Gnathostoma hispidum and Gnathostoma doloresi].
abstract: To increase understanding of immune response of host against G. hispidum, antigenic recognition of rodent gnathostomiasis were identified by the immunoblot method after PAGE of the advanced third stage larvae of G. hispidum and G. doloresi. The molecular weight of the major antigenic bands of G. hispidum extracts were 35 kDa and 16 kDa, and of G. doloresi were 48 kDa, 37 kDa and 35 kDa. Of these bands, the 35 kDa antigen of G. hispidum and G. doloresi was recognized with the sera of rats infected with G. hispidum 5 weeks after inoculation. Lecting staining with endoglycosidase-H or hydrolytic degradation on nitrocellulose strips revealed that the 35 kDa band of G. hispidum possessed the mannose-rich oligosaccharides. On the other hand, the band of G. doloresi had the hybrid-type glycopeptides. The larval extracts and excretory-secretory materials of G. hispidum were not antigenitically identical.
