Abstract
Aim: Despite the endemic nature of contagious ecthyma in Nigeria, there is limited report on the molecular characterization of the isolates responsible for disease outbreaks. The aim of this study was to molecularly characterize ORFV isolated from clinical infections in goats in Sokoto metropolis. Materials and Methods: Seronegative embryonated chicken eggs were used to isolate ORFV via the chorio allantoic membrane (CAM) route according to the established protocol. Viral DNA was extracted from infected CAM and the full coding region of B2L gene was amplified by PCR and subsequently sequenced by Sanger’s method. The nucleotide sequence results were blasted for identification and phylogenetically analyzed using MEGA and Bioedit softwares. Results and Discussion: The results showed that B2L gene sequences of the ORFV UDUS/01/19/More strain showed slight variability (96- 98.7%) with the reference sequences. Our isolate clustered within the same clade with Korean strain signifying a close genetic relationship. Unique amino acid substitutions were noted in our isolate when compared with other references. This is arguably the first genetic characterisation of B2L gene of ORFV circulating in Nigeria. Conclusion: Our study has provided in sight into the genetic diversity of ORFV in the study area. This is crucial for the design of effective vaccines against the disease which are currently lacking in the country.
