莱姆病(Lyme disease)又名伯氏疏螺旋体病,是20世纪70年代发现的以蜱为传播媒介,由不同基因型伯氏疏螺旋体(Borrelia burgdorferi sensu lato)感染所致的人兽共患自然疫源性疾病,主要流行于温带和亚热带地区,犬、猫、马、牛、鹿等多种...莱姆病(Lyme disease)又名伯氏疏螺旋体病,是20世纪70年代发现的以蜱为传播媒介,由不同基因型伯氏疏螺旋体(Borrelia burgdorferi sensu lato)感染所致的人兽共患自然疫源性疾病,主要流行于温带和亚热带地区,犬、猫、马、牛、鹿等多种动物易感,人也是该病原菌的易感宿主。人患莱姆病时的主要症状为游走性红斑、关节炎和其他神经系统症状。患病动物常表现的症状是蜱叮咬部位被毛脱落、发热、蹄叶炎、跛行等。莱姆病流行广泛,但是诊断较为困难并极易造成误诊和漏诊。为避免莱姆病对畜牧业以及宠物行业造成不利影响,亟需提高对莱姆病的关注。因此,本文对动物莱姆病及其诊断和防治技术的研究进展进行综述,以期为动物莱姆病的准确、快速诊断和防治提供参考。展开更多
