A comparison of antigenic peptides in muscle larvae of several Trichinellaspecies by two-dimensional western-blot analysis with monoclonal antibodies

The antigens recognised by mAb US5 specific to 53 kDa glycoprotein (gp 53) in T spiralis L-1 muscle larvae (TSL1) antigens, mAb US9 specific to gp 53 in TSL1 from all encapsulated species and mAb US4 specific to a tyvelose co ntaining tetrasaccharide present in TSL1, were investigated in crude extrac ts from muscle larvae of T. spiralis, T. nativa and T. britovi by 2D-electr ophoresis and western-blot At least four proteins of different p(I) were re cognised by mAb US5 on T. spiralis antigens. Recognition profile of mAb US9 on T. spiralis antigens exhibited some variation with regard to that of th e US5. Polymorphism was apparent in gp 53. High reactivity was shown by the mAb US4 with the three species.
