Abstract
Contagious pustular dermatitis is a disease that primarily infects small ruminants and possesses zoonotic potential. It is caused by orf virus (ORFV), a member of the genus Parapoxvirus. In this study, we evaluated an ORFV outbreak in goats in Madhya Pradesh, a state in central India, during 2017. The transboundary potential of this virus was evaluated by constructing phylogenetic trees. The complete genome sequence of an ORFV isolate named Ind/MP/17 was found to be 139,807 bp in length with 63.7% GC content and 132 open reading frames (ORFs) flanked by 3,910-bp inverted terminal repeats (ITRs). An investigation into evolutionary parameters such as selection pressure (θ = dN/dS) and nucleotide diversity (π) demonstrated that ORFV has undergone purifying selection. A total of 40 recombination events were identified, 21 of which were evident in the Ind/MP/17 genome, indicating its ability to generate new variants.
