Abstrakt: | Background: Equine infectious anaemia (EIA) is controlled by the identification of seropositive animals. The official diagnostic method is the agar gel immunodiffusion (AGID) test, which detects antibodies against a viral core protein (p26). Although AGID is inexpensive and specific, the report of results takes considerable time and the test has low analytical sensitivity. Objective: To validate our in-house indirect ELISA Study Design: Test validation. Methods: Synthetic peptides gp90 and gp45 were used as antigens in ELISA Results: We were able to replace the National References Sera with our Internal Reference Sera. ELISA Main Limitations: Samples were derived from naturally infected equid populations showing heterogeneous clinical states: therefore, their status was uncertain and some horses were sampled more than once. The AGID test may not be the most useful gold standard. Conclusion: ELISA (© 2022 EVJ Ltd.) |
