Characteristics analysis of Orf virus from goats to human
Contagious pustular dermatitis (orf) is an exanthemous disease affecting sheep and goats primarily. As a zoonotic infectious disease caused by parapoxvirus, orf should be managed not only in animals but also in humans. In this study, the typical orf clinical symptoms in goat and humans were observed. Human and goat samples were drawn. The Orf virus (orfv) was identified using an electron microscope, and PCR was used to amplify the target for B2L gene sequence. Molecular analysis of other B2L gene sequences downloaded from GenBank was performed by Mega4 soft. Results indicated that a 21-year old girl who worked in a goat farmcontacted orfv infection from infected goats directly. Eleven amino acid (AA) mutations were detected in the goat orfv transmitted to human orfv. Phylogenetic analysis showed that human orfv in this study was closely related genetically to FJ-SJ2 (KC568397), which was isolated from Fujian province 2012. The results facilitate the development of programs to control Orf virus infections not only in goats but also in humans.
