A zoonotic, opportunistic out-break of tropical rat mite Ornithonyssus bacoti [Acari: Macronyssidae; Ornithonyssus bacoti (Hirst)] in an animal facility, is described. Immunocompetent mice [Mus musculus (Linnaeus)] and rat [Rattus norvegicus (Berkenhout)] strains in a conventional health status facility suffered from scratching and allopecia and staff members suffered from pruritic, erythemato-papular lesions, presumed to be allergic in origin. O. bacoti was identified and treatment with a 0.1% ivermectin solution led to its complete erradication. Safety assessment revealed no signs of acute toxicity in any animal strain. Following this inexpensive strategy, 7 wk after the initial dose, samples were negative for the presence of acari. At the time of this report, 26 months after diagnosis, O. bacoti remains undetected.
本文描述了动物设施中热带鼠螨巴氏禽刺螨[蜱螨亚纲：巨刺螨科；巴氏禽刺螨（赫斯特）]的一次人畜共患、机会性暴发。在一个常规健康状况的设施中，具有免疫能力的小鼠[小家鼠（林奈）]和大鼠[褐家鼠（伯克霍特）]品系出现抓挠和脱毛症状，工作人员出现瘙痒性红斑丘疹病变，推测为过敏性病变。已鉴定出巴氏禽刺螨，用0.1%伊维菌素溶液治疗后其被彻底根除。安全性评估显示，任何动物品系均未出现急性毒性迹象。采用这种低成本策略后，初始剂量7周后，螨虫样本检测呈阴性。在本报告发布时，诊断后26个月，仍未检测到巴氏禽刺螨。
