Seroprevalence of Coxiella burnetii infection in cattle on Ulleung Island, Korea

ABSTRACT

We assessed the seroprevalence of Coxiella burnetii (C. burnetii) in cattle on Ulleung Island, Korea in a population-based follow up study for 4 years and determined the spatial distribution and risk factors associated with C. burnetii. The seroprevalence of C. burnetii was determined to be 1.4–2.0% during 2011–2014. Overall, nine cattle from three farms that tested seropositive showed C. burnetii antibody seroconversions between 2011 and 2014. The number of seropositive cattle was low, suggesting that movement of and contact between animals was possible risk factors for the transmission of C. burnetii.
