title: Identification of mouth part antigens of Fasciola gigantica and Toxocara vitulorum and its molecular targets recognized by homologous and heterologous adult anti-sera against adult.
abstract: Sodium dodecyl sulphate poly-acrylamide gel electrophoresis (SDS-PAGE) fractionation of whole-worm and mouth part antigens of F. gigantica and T. vitulorum showed obvious qualitative and quantitative differences. Three different anti-sera, raised in rabbits against adult extracts of F. gigantica, T. vitulorum and Monieza expansa, were utilized in immunoblotting for identification of mouth part antigens that cross-react with adult worm of the same species or of different species. 7 and 8 poly peptides were recognized in F. gigantica and T. vitulorum mouth parts respectively by their homologous rabbits anti-adult anti-sera. The cross reactive antigens in F. gigantica which recognized by T. vitulorum anti-sera was 234 KD, while two components of M.wt. 113 and 93 KD were detected by M. expansa serum in the same extract. Furthermore, T. vitulorum antigens which cross-reacted with F. gigantica anti-serum 150 and 65 KD and with M. expansa were 65 and 49 KD.
