- A novel reverse-transcription, loop-mediated isothermal amplification (RT-LAMP) assay for the detection of bovine ephemeral fever virus (BEFV) was developed and evaluated in this study. The RT-LAMP assay exhibited higher sensitivity when compared with conventional reverse-transcription polymerase chain reaction (RT-PCR) and virus isolation methods. The specificity of the assay was determined by digestion of the RT-LAMP products with restriction enzyme and detection of BEFV serogroup rabies virus (RV). Using RT-LAMP, RT-PCR and virus isolation methods, 36 blood samples were tested and the results indicated that RT-LAMP could detect early infection with BEFV. The RT-LAMP method is useful for the diagnosis of BEFV infection in blood samples.
