ABSTRACT
Lumpy Skin Disease (LSD), a poxvirus disease affecting cattle, emerged in India in 2019 and intensified in 2022, resulting in significant economic losses for dairy farmers. There was unusual shift in mortality and morbidity patterns during the second wave. A comprehensive genetic study conducted, analyzing samples from 2019 to 2022 revealed circulation of two distinct subclades (subclade 1.2a and 1.2b) in India, with the latter showing a different pattern in morbidity and mortality. Notably, the Ankyrin repeats gene-based analysis could differentiate animals with varying clinical scores. Genetic variations were significant, with unique deletions identified, including a 12-nucleotide deletion in the GPCR gene in virus isolates collected during 2022 outbreaks, not reported earlier in Indian LSDV strains. A crucial finding was a significant 95-nucleotide deletion in the Functional Resolution Sequence (FRS) repeats of LSDV genomes from 2022 outbreaks, absent in 2019 samples. These deletions may have influenced the virus's virulence in India.
