Popis: | A two-step SYBR-Green I-based real-time PCR with melting curve analysis was developed to detect and differentiate the avian reovirus (ARV) sigmaC gene in field and vaccine ARVs. Three primer sets were used to amplify the sigmaC gene from its 5', center, and 3' regions and analyze the melting point temperatures of nine ARVs. By combining the melting curves of the three ARV sigmaC gene regions, melting curve analysis could accurately distinguish the ARVs of different subtypes, and the results were consistent with phylogenetic analysis. The ARV sigmaC gene polymorphisms from different strains were also used to explain the differences in melting point temperatures. Compared with traditional subtyping methods, the current melting curve analysis provided an accurate test for separating ARVs, thereby making it a useful method for the improved selection of ARV vaccines. |
