Abstract:  Objective] To amplify and clone Cysticercus cellulosae AgB cDNA coding region. [Methods] The AgB cDNA was amplified by RT-PCR technique from the total RNA of Cysticercus cellulosae. It was cloned into the vector pUC118 and sequenced. [Results] The PCR amplified product was a single band of 2.6 kb in size. The sequences of AgB cDNA coding region has 99.8% homology with that of Australian Cysticercus cellulosae, and their amino acid sequences have 99.3% homology. [Conclusion] Cysticercus cellulosae AgB cDNA coding region has been cloned successfully.\;
