Parasitic otitis associated with psoroptes infestation was diagnosed in a small pedigree flock of sheep with aural haematomas, abscessation and cauliflower ears. Thirteen of the 15 lambs were affected but the clinical signs were mild; small, discrete, crusty lesions on the inner aspect of the ear at the junction of its anterior and posterior borders were typical. Nine of the 20 adults were affected but the lesions were more severe. Eighteen of the 64 members of the breed society who responded to a telephone survey reported sheep with similar clinical signs in their flocks. The proportion of animals affected ranged from 1 to 60 per cent with a median value of 16 per cent.
在一个患有耳血肿、脓肿和菜花样耳朵的小型纯种绵羊群中，诊断出与痒螨感染相关的寄生虫性中耳炎。15只羔羊中有13只受到影响，但临床症状较轻；耳朵前后边缘交界处内侧出现小而分散的结痂病变是其典型症状。20只成年羊中有9只受到影响，但病变更为严重。该品种协会64名成员中有18人回复了电话调查，报告称他们的羊群中有羊出现类似临床症状。受影响动物的比例在1%至60%之间，中位数为16%。
