title: Brucellosis seroprevalence among workers in at-risk professions: northwestern Wyoming, 2005 to 2006.
abstract: OBJECTIVE
  Brucellosis is uncommon in the United States; however, its circulation among wildlife and domestic cattle has been ongoing in Wyoming. To assess the public health threat of brucellosis circulation among animals, a seroprevalence study was undertaken among workers in professions considered to be at the highest risk for infection.
  
  
  METHODS
  A seroprevalence study was undertaken targeting individuals in at-risk professions in the affected area of the state.
  
  
  RESULTS
  Seroprevalence among study participants was 14.4%. Veterinarians were the main professional group that demonstrated a statistically significant association with measurable anti-Brucella antibodies. Vaccinating animals with Brucella vaccines was associated with seropositivity.
  
  
  CONCLUSIONS
  The risk to the general public's health from the circulation of Brucella among wildlife and cattle can be attributed primarily to a limited subpopulation at high risk rather than a generally elevated risk.
