Abstract
A total of 123 Coxiella burnetii strains detected in cattle from a nationwide survey in Korea were classified into five genomic groups: I (0.8%), II (14.6%), III (12.2%), IV (66.7%), and V (5.7%). Acute Q-fever strains (Groups I, II, and III) comprised 27.6% and chronic strains (Groups IV and V) comprised 72.4%. At a dairy farm where both types were present, the detection rate was 6.7-times higher than that of another farm where only chronic strains were detected. Both acute and chronic Q-fever strains are widespread in Korea, and their presence could represent an active transmission to livestock and humans.
