The recovery of a Haemaphysalis longicornis Neumann (Acari: Ixodidae) tick from a dog in Benton County, Arkansas, in 2018 triggered a significant environmental sampling effort in Hobbs State Park Conservation Area. The objective of the investigation was to assess the tick population density and diversity, as well as identify potential tick-borne pathogens that could pose a risk to public health. During a week-long sampling period in August of 2018, a total of 6,154 ticks were collected, with the majority identified as Amblyomma americanum (L), (Acari: Ixodidae) commonly known as the lone star tick. No H. longicornis ticks were found despite the initial detection of this species in the area. This discrepancy highlights the importance of continued monitoring efforts to understand the dynamics of tick populations and their movements. The investigation also focused on pathogen detection, with ticks being pooled by species, age, and sex before being processed with various bioassays. The results revealed the presence of several tick-borne pathogens, including agents associated with ehrlichiosis (n = 12), tularemia (n = 2), and Bourbon virus (BRBV) disease (n = 1), as well as nonpathogenic rickettsial and anaplasmosis organisms. These findings emphasize the importance of public health messaging to raise awareness of the risks associated with exposure to tick-borne pathogens. Prevention measures, such as wearing protective clothing, using insect repellent, and conducting regular tick checks, should be emphasized to reduce the risk of tick-borne diseases. Continued surveillance efforts and research are also essential to improve our understanding of tick-borne disease epidemiology and develop effective control strategies.

从阿肯色州本顿县现场采集的蜱虫以及相关病原体的流行情况

2018 年，在阿肯色州本顿县的一只狗身上发现了长角血蜱（螨虫：蜱科）蜱虫，引发了霍布斯州立公园保护区的重大环境采样工作。调查的目的是评估蜱虫种群密度和多样性，并确定可能对公共健康构成风险的潜在蜱传病原体。在 2018 年 8 月为期一周的采样期间，共采集了 6,154 只蜱虫，其中大多数被鉴定为美洲钝蜱（Amblyomma americanum (L)）（螨虫：蜱科），俗称孤星蜱。尽管最初在该地区发现了 H. longicornis 蜱，但并未发现该物种。这种差异凸显了持续监测工作以了解蜱虫种群动态及其运动的重要性。该调查还侧重于病原体检测，将蜱虫按物种、年龄和性别汇集起来，然后进行各种生物测定。结果显示存在多种蜱传病原体，包括与埃利希体病 (n = 12)、兔热病 (n = 2) 和波旁病毒 (BRBV) 疾病 (n = 1) 相关的病原体，以及非致病性立克次体和无形体病有机体。这些发现强调了公共卫生信息传递的重要性，以提高人们对接触蜱传病原体相关风险的认识。应强调预防措施，例如穿防护服、使用驱虫剂和定期进行蜱虫检查，以降低蜱传疾病的风险。持续的监测工作和研究对于提高我们对蜱传疾病流行病学的了解并制定有效的控制策略也至关重要。
