Abstract |
A codon-optimized equine infectious anemia virus p26 gene was fused to a maltose-binding protein (MBP) and expressed in Escherichia coli for use as an antigen in agar gel immunodiffusion (AGID) and enzyme-linked immunosorbent assay (ELISA) for diagnosis of equine infectious anemia. An analysis of analytical sensitivity and specificity showed that the antigen MBP-p26rec reacted positively with a reference World Organization for Animal Health serum and demonstrated no cross-reaction against sera from vaccinated animals in either test. The diagnostic characteristics were evaluated and presented excellent values. The AGIDrec showed 100% sensitivity and specificity, and the ELISArec showed 100% sensitivity and 99.64% specificity. In addition, MBP-p26rec was stabile after three years of storage at 4 °C, maintaining its immunoreactivity. |
