5'-UTR-based phylogenetic analysis of Classical swine fever virus isolates from India.
Classical swine fever (CSF) caused by Classical swine fever virus (CSFV) is a globally significant disease of pigs. Genetic typing of CSFV isolates can help in understanding the epidemiology of disease and trace down the source of outbreak. 5'-UTR sequence analysis and subsequent genetic classification of nine CSFV field isolates from India indicated that 3 isolates belonged to genotype 2.1 and were closely related to European CSFV strains. The remaining 6 isolates belonged to genotype 1 that contained old and new strains. However, the genotype 2.1 group consisted of recent field isolates only. The study showed circulation of both genotypes 1 and 2.1 in north-eastern part of India.
