婴儿头癣3例及其家属头皮无症状携带同一病原菌

Three cases of infantile tinea capitis with asymptomatic family members carrying the same pathogens on their scalp

目的:探讨头癣患儿家属的头皮无症状携带情况。方法:取患儿病发及其家属头皮行真菌直接镜检和真菌培养,并分析头癣类型、病原菌特点以及患儿及其家属的病原菌同源性情况。结果:3例头癣患儿包括2例脓癣和1例黑点癣。3例患儿家属(5例)均存在头皮无症状携带皮肤真菌,且病原菌均与患儿一致,其中1例为断发毛癣菌,2例为紫色毛癣菌。3例患儿予口服抗真菌药治疗后均治愈。结论:头癣患儿的家属可能存在无症状携带皮肤真菌的可能,不利于头癣疾病流行的防治,应引起关注并及时采取预防或治疗干预。

Objective:To study the asymptomatic carries in the family members of the infants with tinea capitis.Methods:The damaged hairs from the infants with tinea capitis and scalps of their family members were examined under microscopy and in culture for fungi.The types of tinea capitis,the characteristics,and the comparison of pathogens between the infants and their family members were analyzed.Results:There were 3 cases of tinea capitis in infants identified,2 of which were kerion celsi,and 1 of which was black dot tinea.All these three cases had the family members(total 5 adults) carrying the same pathogens on their scalps as that of 3 patients.The pathogens were identified as one Trichophyton tonsurans and two Trichophyton violaceums.All these three infantile patients were cured by oral antifungal drugs.Conclusions:The family members of the tinea capitis in infants may asymptomatically carry the pathogens on their scalps,which would be ineffective for the prevention and treatment and should be a concern for controlling tinea capitis.
