Given the variable clinical signs attributed to Borrelia burgdorferi, including infectious arthritis, neurologic disease, and behavioral changes, B burgdorferi is an important differential for decreased performance in sport horses. The primary vectors (Ixodes tick species) are expanding their range and thus Borrelia species are located in a wider area, making exposure more likely. Due to regionally high seroprevalence and vague clinical signs, diagnosis of Lyme disease in the horse is believed overestimated. Antibiotics are first-line treatment of confirmed Lyme disease. A single positive serologic test, by itself, is not conformation of Lyme disease but is evidence of current or past infection.
鉴于伯氏疏螺旋体可引发多种不同的临床症状，包括感染性关节炎、神经疾病和行为改变，它是运动马匹表现下降的一个重要鉴别诊断因素。主要传播媒介（硬蜱属蜱种）的分布范围正在扩大，因此疏螺旋体物种分布的区域更广，马匹更易接触到。由于局部血清阳性率较高且临床症状不明确，人们认为马匹莱姆病的诊断可能存在高估。抗生素是确诊莱姆病的一线治疗药物。单一的血清学检测呈阳性本身并不能确诊莱姆病，但可证明当前或过去曾感染过。
