We found Rickettsia parkeri in Amblyomma ovale ticks collected in Veracruz, Mexico, in 2018. We sequenced gene segments of gltA, htrA, sca0, and sca5; phylogenetic reconstruction revealed near-complete identity with R. parkeri strain Atlantic Rainforest. Enhanced surveillance is needed in Mexico to determine the public health relevance of this bacterium.
我们在 2018 年于墨西哥韦拉克鲁斯州采集的孤星钝缘蜱中发现了帕克氏立克次体。我们对 gltA、htrA、sca0 和 sca5 基因片段进行了测序;系统发育重建显示与大西洋雨林株帕克氏立克次体的近乎完全一致。墨西哥需要加强监测,以确定该细菌对公共卫生的相关性。
