莱姆病是马里兰州最常见的蜱传疾病，由严格伯氏疏螺旋体引起，最常见的传播媒介是肩背硬蜱（硬蜱科：硬蜱科）。BecauseB。伯氏体在野生小鼠（Peromyscus spp）和蜱虫（dixodes spptis）之间保持着地方性循环，蜱虫寄生在小鼠身上的不同模式可能影响伯氏体的感染流行。burgdorferi。我们确定了2020年5月至8月在马里兰州5个县的私人土地上的6个地点收集的sppas peromyscus感染流行率以及探索和部分充血的蜱虫。探索若虫感染患病率（NIP）为14%。共捕获小鼠1258只，收集蜱虫554只，耳组织样本413份。受感染的孢子虫的患病率因宿主的年龄和性别而异，老年和雄性小鼠更容易被感染。我们发现附着的dixodesi比例和诱捕地点之间存在显著差异。同样，b。感染伯氏多夫氏菌的spspus小鼠在不同地点有所不同（小鼠平均感染率为40%），在蜱虫最常发现的地点患病率最高。TheB。burgdorferi感染在部分地区的流行。从peromyscus spsp中提取的肩胛骨若虫约占36%，这进一步支持了宿主感染的患病率。在规划降低莱姆病风险的干预措施时，感染媒介和宿主分布的地方差异是需要考虑的重要因素。
Lyme disease, caused byBorrelia burgdorferisensu stricto and most commonly transmitted byIxodes scapularisSay (Ixodida: Ixodidae), is the most common tick-borne disease in Maryland. BecauseB. burgdorferi s.s.is maintained in enzootic cycles among wild mice (Peromyscus spp) andIxodes sppticks, differing patterns of parasitism of ticks on mice could impact the infection prevalence withB. burgdorferi. We determined the infection prevalence ofPeromyscus sppas well as questing and partially engorged nymphal ticks collected at six sites on private land in five counties in Maryland from May to August 2020. Questing nymph infection prevalence (NIP) was 14%. We trapped 1258 mice and collected 554 ticks and 413 ear tissue samples. The prevalence of infestedPeromyscus sppvaried based on host age and sex, with older and male mice more likely to be infested. We detected a significant difference amongst the proportion of attachedIxodesand the location of trapping. Similarly, the prevalence ofB. burgdorferiinfectedPeromyscus sppmice varied between locations (average mouse infection prevalence was 40%), with the highest prevalence in locations whereIxodeswere the most commonly found ticks. TheB. burgdorferiinfection prevalence in partially engorgedI. scapularisnymphs retrieved fromPeromyscus sppwas ~36% which lends further support to the host infection prevalence. Local differences in distribution of infected vectors and reservoirs are important factors to consider when planning interventions to reduce Lyme disease risk.
