Abstract

Abstract Sheep pox is a highly contagious infectious viral disease (F/Poxviridae, G/Capripoxvirus), still causing economic damage in endemic zones like northern Africa, the Middle East, and many regions in Asia. Nevertheless, the clinical symptoms caused by sheep pox virus (SPPV) is similar to those caused by genetically related viruses, notably goat pox virus (GTPV) and lumpy skin disease virus (LSDV). One of the main objectives of the current study is to characterize the virus; nasal swabs were taken from sheep showing SPPV clinical signs, submitted to molecular sequencing based on the P32 gene marker, and proceeded to genetic comparisons. Phylogenetic results showed that all virus isolate sequences cluster in the SPPV clade, thus distinguishing them from those of GTPV and LSDV. These results give an accurate diagnostic and a clear view of endemic viral strains, guiding veterinary managers in control politics, especially in the choice of a homologous vaccine.
