Bovine papular stomatitis virus (BPSV) infections in Korean native cattle.

An outbreak of a disease with parapox-like symptoms was reported in South Korea in April 2012. Three of 45 Korean native cattle, age 20-24 months, were affected. Parapoxviruses were detected and identified by electron microscopy and polymerase chain reaction (PCR). To determine the genetic characteristics of the Korean strains, the sequence of the major envelope protein (B2L) was determined and compared with published reference sequences. Phylogenetic analysis revealed that the parapoxvirus strains were closely related to not only isolates from Japan, but also isolates from Germany, Sudan and the United states. This is the first report on an outbreak and the molecular characterization of BPSV in Korea.
