Lyme disease has been recognized in humans since 1975 when it was associated with an outbreak of oligoarthritis in children in Lyme, Connecticut. Erythema chronicum migrans (ECM) is a clinical marker for the human disease, which usually appears within 3 to 32 days after an infected tick bite. Lyme disease is caused by spirochete, Borrelia burgdorferi, which is vectored by the hard ticks Ixodes dammini or Ixodes pacificus in the United States. In humans, Lyme disease has been found to cause a variety of clinical syndromes including cardiopathy, neuropathy, dermatopathy, and arthropathy. Human Lyme carditis is characterized by varying degrees of atrioventricular (AV) heart block that usually resolve regardless of therapy. Lyme disease has been reported in the dog as an arthropathy. This article reports a case of complete heart block and myocarditis in a dog with a positive titer for B burgdorferi, in which clinical and pathologic findings were similar to those seen in human Lyme myocarditis.
自1975年莱姆病与美国康涅狄格州莱姆镇儿童寡关节炎暴发相关联以来，它已被确认为一种人类疾病。慢性游走性红斑（ECM）是这种人类疾病的临床标志，通常在被感染的蜱叮咬后3至32天内出现。莱姆病由螺旋体伯氏疏螺旋体引起，在美国由硬蜱达米尼硬蜱或太平洋硬蜱作为传播媒介。在人类中，已发现莱姆病会引发多种临床综合征，包括心脏病、神经病变、皮肤病和关节病。人类莱姆心肌炎的特征是不同程度的房室传导阻滞，通常无论是否接受治疗都会缓解。莱姆病在犬类中被报道为一种关节病。本文报告了一例犬类完全性心脏传导阻滞和心肌炎病例，该犬伯氏疏螺旋体滴度呈阳性，其临床和病理表现与人类莱姆心肌炎相似。
