Ovine laryngeal chondritis is a rare entity of sheep in the USA, Great Britain, New Zealand and Iceland, but has not been reported in Germany so far. Here, two German cases are reported.
Two rams showed severe and progressive signs of dyspnea. Endoscopically, a severe bilateral swelling of the larynx was identified in both rams. Due to poor prognosis and progression of clinical signs one ram was euthanized, while the other ram died overnight. In both cases, a necrosuppurative laryngitis and chondritis of arytenoid cartilages was found at necropsy. Fusobacterium necrophorum and Streptococcus ovis were isolated from the laryngeal lesion in one animal.
This is the first report of ovine laryngeal chondritis in continental Europe. This entity should be considered a differential diagnosis for upper airway disease in sheep.
绵羊喉软骨炎在美国、英国、新西兰和冰岛较为罕见，但目前尚未在德国报道过。在此，报告两例德国病例。
两只公羊出现严重且进行性呼吸困难症状。内镜检查发现，两只公羊的喉部均出现严重的双侧肿胀。由于预后不良和临床症状的进展，一只公羊被安乐死，另一只公羊则在夜间死亡。在这两种情况下，尸检均发现会厌软骨的坏死性化脓性喉炎和软骨炎。在一只动物的喉部病变中分离出坏死梭杆菌和绵羊链球菌。
这是绵羊喉软骨炎在欧洲大陆的首例报告。该病症应被视为绵羊上呼吸道疾病的鉴别诊断。
