Development of a fluorescent probe-based recombinase polymerase amplification assay for rapid detection of Orf virus.

ABSTRACT:

Background

Orf virus (ORFV) is the causative agent of Orf (also known as contagious ecthyma or contagious papular dermatitis), a severe infectious skin disease in goats, sheep and other ruminants. The rapid detection of ORFV is of great importance in disease control and highly needed. A isothermal molecular diagnostic approach, termed recombinase polymerase amplification (RPA), is considered as an novel and rapid alternative techonology to PCR assay.

Results

In the present study, a novel fluorescent probe based on RPA assay (ORFV exo RPA assay) was developed. The developed ORFV exo RPA assay was capable of as low as 100 copies of ORFV DNA /reaction and was highly specific, with no cross-reaction with closely related viruses (capripox virus, foot-and-mouth disease virus or pe
