Laboratory-reared and field-collected Amblyomma americanum ticks were hosts of a Coxiella sp. and a Rickettsia sp. While the Coxiella sp. was detected in 50 of 50 field-collected ticks, the Rickettsia sp. was absent from 32% of ticks. The Coxiella sp. showed evidence of a reduced genome and may be an obligate endosymbiont.
实验室饲养和野外采集的美洲钝眼蜱是一种考克斯氏体属细菌和一种立克次氏体属细菌的宿主。虽然在50只野外采集的蜱虫中均检测到了考克斯氏体属细菌,但32%的蜱虫中未检测到立克次氏体属细菌。考克斯氏体属细菌显示出基因组缩减的迹象,可能是一种专性内共生菌。
