摘要
[ Objective] To analyze Eimetria acervulina cSZl gene sequence and thus to find a candidate antigen for vaccine development.[ Method] According to the cSZl gene sequence of Eimeria acervulina published in GenBank, a pair of specific primers was designed. Then, the cSZl gene of Eirneda acervulina Changchun strain was amplified by reverse-transcription polymerase chain reaction （RT-PCR） and sequenced. [ Result] Compared with the published cSZ1 gene sequence, five nucleotide mutation sites appeared in the cSZ1 gene of Eirneda acervulina Changchun strain. They had a nucleotide sequence similarity of 99.47%, and their encoding region had a nucleotide sequence similarity of 99.61%. Among these mutation sites, two appeared in cSZl gene ORF, and A185G mutation led to substitution of valine by isoleucine. [Conclusion] Protein encoded by cSZ1 gene can be used as a candidate antigen for vaccine development.
