Potential link of single nucleotide polymorphisms to virulence of vaccine-associated field strains of lumpy skin disease virus in South Africa.

South Africa is endemic for lumpy skin disease and is therefore reliant on various live attenuated vaccines for the control and prevention of the disease. In recent years, widespread outbreaks of vaccine-like strains of lumpy skin disease virus (LSDV) were reported internationally, leading to an increase in the generation of full genome sequences from field isolates. In this study, the complete genomes of six LSDVs submitted during active outbreaks in the 1990s in South Africa were generated.

Lumpy skin disease of cattle: an emerging problem in the Sultanate of Oman.

Lumpy skin disease (LSD) is a highly infectious disease of cattle caused by a virus belonging to the Capripoxvirus genus of the family Poxviridae. The purpose of this study is to place on record the first confirmation of LSD in the Sultanate. The disease was diagnosed and confirmed using polymerase chain reaction, histopathology, transmission electron microscopy and serum neutralization testing.

Improved method for the generation and selection of homogeneous lumpy skin disease virus (SA-Neethling) recombinants.

Lumpy skin disease virus (LSDV) is being developed as a vector for recombinant vaccines against diseases of veterinary importance. A strategy for generating viral thymidine kinase (TK) gene-disrupted recombinants which are stable and homogeneous using the South African Neethling vaccine strain of LSDV as vector has been developed. To assist with the selection process, the Escherichia coli beta-galactosidase (lacZ) visual marker gene was incorporated into the constructs.
