摘要： Orf is a non-systemic, ubiquitous disease of sheep and goats caused by the orf virus (ORFV). ORFV occasionally causes cutaneous lesions in humans in contact with infected animals. In the present study, a real-time PCR method was established for detection of ORFV using the fluorescent chimeric dye SYBR Green I. Specific primers were designed to target a highly conserved region of the ORFV B2L gene. This method was able to detect a minimum of 20 copies of ORFV genomic DNA. The results showed no cross-reactions with other common DNA viruses. The time required for the test was approximately 1.5 h. Clinical test samples showed that this method was faster and had a higher sensitivity than traditional PCR. In conclusion, this novel, real-time PCR-based assay provides a rapid, sensitive, and specific method for ORFV detection. This test provides improved technical support for studies regarding the clinical diagnosis and epidemiology of ORFV.
