Introduction: The work has been attempted to detect and genetically characterise the nature of Bovine Viral Diarrhea Virus (BVDV) isolates from the porcine population of the north east.
Methods and material: The samples have been collected over a two year period and are from areas where there is a mixed and integrated rearing of livestock in close proximity. The isolates were identified, cloned and sequenced using BVD specific genomic primers for two important domains viz., E-2 and 5' UTR.
Results: Porcine BVD Sequences were analysed phylogenetically. Divergence in 3 sequences is noted in the 5' UTR region that are forming a clear outlier group while E-2 sequences are coming close to BVDV group but forming a separate cluster.
