Porcine reproductive and respiratory syndrome virus (PRRSV) from the first outbreak of India shows close relationship with the highly pathogenic variant of China

Abstract

Sequence and phylogenetic analysis of ORF5 and ORF7 confirmed that the Indian strain has a close link with the HP-PRRSV of China. The current study forms an essential step for better understanding of the epidemiology as well as the movement and spread of the disease in India.
