Development of a quantitative real-time RT-PCR assay for detecting Taiwan ferret badger rabies virus in ear tissue of ferret badgers and mice.

ABSTRACT: In 2013, the first case of Taiwan ferret badger rabies virus (RABV-TWFB) infection was reported in Formosan ferret badgers, and two genetic groups of the virus were distinguished through phylogenetic analysis. To detect RABV-TWFB using a sensitive nucleic acid-based method, a quantitative real-time reverse transcription polymerase chain reaction targeting the conserved region of both genetic groups of RABV-TWFB was developed. This method had a limit of detection (LOD) of 40 RNA copies/reaction and detected viral RNA in brain and ear tissue specimens of infected and dead Formosan ferret badgers and mice with 100% sensitivity and specificity. The mean viral RNA load detected in the ear tissue specimens of ferret badgers ranged from 3.89 × 108 to 9.73 × 108 RNA copies/g-organ, which was 111-f
