Abstract An outbreak of orf virus infection in dairy goats in Korea was investigated. Suspected samples of the skin and lip of affected goats were sent to the laboratory for more exact diagnosis. Orf virus was detected by electron microscopy and viral DNA was identified by PCR. To reveal the genetic characteristics of the Korean strain ORF 09 Korea the sequences of the major envelope protein B2L and orf virus interferon resistance VIR genes were determined and then compared with published reference sequences. Phylogenetic analysis revealed that the ORF 09 Korea strain was closest to the isolates Taiping from Taiwan. This is believed to be the first report on the molecular characterization of orf virus in Korea. Background Contagious ecthyma contagious pustular dermatitis orf is a common epitheliotrophic viral disease of sheep
