We evaluated (lone star tick) and (American dog tick) in northeast Missouri for the presence of , , and bacteria and Heartland virus. We screened 436 individual adult lone star ticks (86% of all ticks collected) and infection rates were 6% for , 19% for , 3% for , 36% for and 1% for . In the 189 individual American dog ticks, infection rates were 19% for , 15% for , 4% for , and 5% for . In addition, we screened 20 pools of adults and 30 pools of nymphs for the Heartland virus which was not detected. Understanding the presence and epidemiology of these causative ( and ) and suspected () agents in Missouri should increase awareness of potential tick-borne disease in the medical community.
我们在密苏里州东北部对孤星蜱和美洲犬蜱进行了评估，以检测嗜吞噬细胞无形体、伯氏疏螺旋体、莱姆病螺旋体和心脏地带病毒的存在情况。我们筛查了436只成年孤星蜱个体（占所有采集蜱虫的86%），嗜吞噬细胞无形体的感染率为6%，伯氏疏螺旋体为19%，莱姆病螺旋体为3%，立克次体属为36%，心脏地带病毒为1%。在189只美洲犬蜱个体中，嗜吞噬细胞无形体的感染率为19%，伯氏疏螺旋体为15%，莱姆病螺旋体为4%，立克次体属为5%。此外，我们对20组成年蜱虫和30组若虫进行了心脏地带病毒筛查，但未检测到该病毒。了解密苏里州这些病原体（嗜吞噬细胞无形体和伯氏疏螺旋体）和疑似病原体（立克次体属）的存在情况及流行病学，应能提高医学界对潜在蜱传疾病的认识。
