|
Seroprevalence of Coxiella burnetii (Q fever) in bulk-tank milk and cattle in Daegu area was analyzed from 2017 to 2018 by ELISA. The prevalence of antibodies in collected bulk-tank milk from 12 dairy cattle farms was 41.7% (10/24) and the seroprevalence of 249 cows reared in the area of Daegu was 3.2% (8/249) By age, the seroprevalence was 1.9% (2/105) in less than 2 years of age, 4.2% (5/119) between 3 and 5 years of age and 4.0% (1/25) in more than 6 years of age. By breed, the seroprevalence of the Hanwoo cattle was 1.2% (2/162) and the seroprevalence of the dairy cattle was 6.9% (6/87). The result suggested that seroprevalence of C. burnetii was relatively high in both bulk-tank milk samples and dairy cattle than the Hanwoo cattle. Based on these data, it is necessary to keep monitoring the prevalence of Q fever in Daegu area.
