Development of a TaqMan-based real-time assay for the specific detection of canine astrovirus.

Abstract In this study, a TaqMan-based real-time polymerase chain reaction (PCR) method to detect canine astrovirus in clinical samples was developed. Primers and probes were designed to target conserved regions of the complete viral genome sequence. The results showed that the proposed method can detect a minimum of 101 copy numbers. No cross-reactivity with other canine and feline viruses was observed. The coefficient of variation was
