Abstract
Lumpy skin disease (LSD) is a financially significant Capripoxvirus-induced disease of cattle . Despite Egyptian veterinary officials' comprehensive immunisation programme, LSDV is still prevalent and widespread throughout the country. Understanding molecular epidemiology is critical for developing better LSD eradication and control measures.. The present research was designed to assess the genetic relatedness between newly strain from Menofia governorate 2020 and previously isolated field and vaccinal strains through molecular characterization and phylogenetic analysis. During the summer of 2020, ten skin tissue samples were taken from LSD-infected cattle that were involved in the epidemic. LSDVs were detected in clinical samples using PCR targeting the GPCR gene. By PCR, all ten samples tested positive for LSDV. One of these PCR-positive samples and the vaccinal strain were then amplified and sequenced for molecular characterization utilising a G-protein coupled chemokine receptor (GPCR) gene, ORF95 and ORF103. Phylogenetic analysis indicated that LSDV strain circulating in Egypt 2020 was closely related with sequences previously isolated from Egypt and that from neighboring countries. A comparison of the GPCR, ORF095, and ORF103 genes revealed that outbreak isolate dissimilar from strain included in vaccine. This information is essential for comprehending LSDV molecular epidemiology and to contribute to the Egyptian government's development strategies of control methods.
