Myiasis, a term used to describe the infestation of a live animal by fly larvae, is rarely reported in human subjects. The adult fly lays its eggs on living tissue that progresses to become larvae that feed on living tissue having gone through three developmental stages known as the first, second and third instar. The larvae become pupae before finally developing into adults.
We describe an unusual case of a 79-year-old female who collapsed in her garden and lay there for several days before presenting to her local hospital Accident and Emergency department with an infestation of larvae in her vagina labia, identified as those from the species northern blowfly. After complete removal of the larvae using tweezers followed by cleansing of the affected area and a course of antibiotics, the patient's condition improved. A follow-up review by the local gynaecology team revealed no evidence of further infestation.
It is our understanding that this is the first highly unusual case of a blowfly larvae infestation to be reported in a human within the UK.
蝇蛆病是一个用于描述活体动物被蝇幼虫寄生的术语，在人类中鲜有报道。成年苍蝇在活体组织上产卵，这些卵会发育成幼虫，幼虫以经过三个发育阶段（即一龄、二龄和三龄）的活体组织为食。幼虫在最终发育成成虫之前会变成蛹。
我们描述了一例不同寻常的病例，一名79岁女性在自家花园中晕倒，在那里躺了几天后才前往当地医院的急诊科就诊，其阴道阴唇被鉴定为来自北方绿头苍蝇的幼虫寄生。用镊子将幼虫完全清除，随后对受影响区域进行清洗并给予一个疗程的抗生素治疗后，患者的病情有所改善。当地妇科团队的随访复查显示没有进一步寄生的迹象。
据我们所知，这是英国境内首例报道的人类被绿头苍蝇幼虫寄生的极为罕见的病例。
