title: Antigenic evidence of bluetongue virus from small ruminant population of two different geographical regions of Odisha, India.
abstract: OBJECTIVE
  The aim of the present study was to carry out antigenic detection of bluetongue virus (BTV) among the small ruminant population of two different geographical regions of Odisha (coastal and central) using recombinant VP7 (r-VP-7) based sandwich enzyme-linked immunosorbent assay (s-ELISA).
  
  
  METHODS
  Blood samples (n=274) were collected from two different geographical pockets of Odisha, which covered mostly the coastal and central regions. Of the total samples under study 185 were from goat and 89 were from sheep. The blood samples were tested for the presence of BTV antigen by r-VP7 based s-ELISA.
  
  
  RESULTS
  r-VP-7 s-ELISA detected BTV antigen in 52.43% and 44.94% of the goat and sheep population under study, respectively. This study highlights the antigenic persistence of BTV in the state for the 1(st) time.
  
  
  CONCLUSIONS
  This high antigenic presence in both sheep and goat population suggests an alarming BTV infection in field conditions which warrants more systematic study directed toward isolation and characterization studies as well as the implementation of control strategy for BT in Odisha.
