Porcine reproductive and respiratory syndrome (PRRS) caused by an arterivirus is characterised by reproductive disorders in sows, and post-weaning pneumonia and growth reduction in piglets. Though the virus has been detected in Kerala, no systematic study has been carried out to ascertain its genotype and molecular epidemiology. In the present study, 7 PRRS virus (PRRSV) positive samples collected from incidences of PRRS in Kerala during 2017-2019 were subjected to ORF5, ORF7 and Nsp2 gene based reverse transcription polymerase chain reaction and the specific amplicons generated were sequenced.

In this paper, we report the detection, G and P typing and phylogenetic analysis of GAR of pigs in Kerala. A total of 100 fecal samples from diarrhoeic piglets were collected from organized farms in Wayanad, Ernakulam, Thrissur, and Palakkad districts of Kerala.

- * Phylogenetic analysis showed that newly evolved isolates were closely related to South Indian strains, with specific mutations found in the isolates, including previously unreported mutations in one isolate.
- * The study also noted that some isolates had high similarity to vaccine strains but still caused outbreaks, marking the first comprehensive genetic characterization of IBDV in the region.
