Prevalence of Coxiella burnetii in native Korean goat in Jeonbuk province

The prevalence of Coxiella burnetii in native Korean goats in Jeonbuk province was investigated using ELISA (sera) and PCR (vaginal mucus). A total of 798 blood samples from 189 farms were collected in 2013 and 2015. Seroprevalence was 13.6% in 2013 and 15.7% in 2015. Tracking survey of six seropositive farms on the prevalence of C. burnetii was conducted. 137 (41.4%) out of 331 goats were seropositive and 47 (17.6%) out of 267 goats were positive in PCR. The higher seropositivity observed in adult goats and female goats significantly, the seroprevalence of C. burnetii was higher as age increased (<1 y=13.2%~ ≥5 y=100%)(P<0.05) and female goats (44.8%) was higher than male goats (24.1%) on the seroprevalence (P<0.05). 21 (7.9%) goats positive in PCR was seronegative. The prevalence of C. burnetii in native Korean goats in slaughter house was 30.0% in ELISA and 11.5% in PCR. Significantly, female goats (62.8%) was higher than male goats (12.3%) on the seroprevalence (P<0.05). Based on these data, C. burnetii was easily exposed in domestic animals: native Korean goats-related areas such as farms and slaughter house.
