title: Seroprevalence of bluetongue in ruminants of Jharkhand.
abstract: OBJECTIVE
  This study was carried out to assess the presence of anti-bluetongue (BT) antibodies in sheep, goat and cattle of different agro-climatic zones of Jharkhand.
  
  
  METHODS
  Serum samples were collected from apparently healthy as well as suspected sheep, goat and cattle from different districts of Jharkhand covering different agro-climatic zones. Serum samples were screened by indirect enzyme linked immunosorbent assay (iELISA) for detecting anti-BT antibodies.
  
  
  RESULTS
  Out of a total of 480 animal serum samples (sheep-190, goats-210 and cattle-80) screened, 83 (43.68%) of sheep, 91 (43.33%) of goat and 46 (57.50%) of cattle sera were found positive. The % positivity ranged between 41% and 51% in different agro-climatic zones. The results showed slight higher seroprevalence, although not significantly, in cattle than sheep and goats in different agro-climatic zones of Jharkhand.
  
  
  CONCLUSIONS
  The above data indicate widespread prevalence of BT virus antibodies in studied areas. The incidence of BT is not detected officially, so far. The present seroprevalence status of BT in Jharkhand indicates presence of BT infection in the state for the first time.
