BACKGROUND
Goats are known reservoirs of Coxiella burnetii, the etiologic agent of Q fever. However, there has been very little research on the prevalence of C. burnetii exposure and risk in meat goats farmed in the US. Banked serum samples were secondarily tested for C. burnetii specific antibodies.
FINDINGS
The animal and herd-level seroprevalence estimates for C. burnetii were 1.2% (3/249) and 4.2% (1/24) respectively. Within-herd seroprevalence ranged from 0% to 1.2%.
CONCLUSIONS
This study indicates that seroprevalence of C. burnetii in Boer goats raised in Missouri was low, but it does not preclude the existence of a higher level of infection in Missouri's meat goat herds. This result is inconclusive because this study was disadvantaged by the small number of individual animal and herds tested, which compromised the statistical power of this study to detect a possible higher seroprevalence of C. burnetii in this population, if present. More research is warranted to corroborate the preliminary findings reported here in order to determine the public health significance C. burnetii infection risks associated with contemporary goat production systems in the US.
背景
山羊是Q热病原体伯氏考克斯氏体的已知宿主。然而，关于美国养殖肉用山羊中伯氏考克斯氏体暴露率和风险的研究非常少。对保存的血清样本进行了伯氏考克斯氏体特异性抗体的二次检测。
研究结果
伯氏考克斯氏体的动物和畜群水平血清阳性率估计分别为1.2%（3/249）和4.2%（1/24）。畜群内血清阳性率范围为0%至1.2%。
结论
本研究表明，密苏里州饲养的波尔山羊中伯氏考克斯氏体的血清阳性率较低，但这并不排除密苏里州肉用山羊群中存在更高感染水平的可能性。由于本研究检测的个体动物和畜群数量较少，影响了本研究检测该人群中伯氏考克斯氏体可能更高血清阳性率（如果存在）的统计效力，因此该结果尚无定论。需要进行更多研究来证实此处报告的初步结果，以确定与美国当代山羊生产系统相关的伯氏考克斯氏体感染风险对公共卫生的意义。
