婴儿头面部脂溢性皮炎马拉色菌带菌情况分析

目的了解患头面部脂溢性皮炎的婴儿与正常婴儿头面部马拉色菌带菌情况及来源分析。方法采用胶带法粘取脂溢性皮炎患儿头面部皮损及其母亲胸前皮肤、正常婴儿额部皮肤及其母亲胸前皮肤等处鳞屑,接种于含菜籽油培养基进行真菌培养,分离马拉色菌,并用生理生化及形态学方法鉴定菌种。结果①4组150例标本中共分离出101株马拉色菌;②脂溢性皮炎患儿与正常婴儿马拉色菌培养阳性率以及菌种构成差异均无显著性意义;③脂溢性皮炎患儿与正常婴儿分别与其母亲的马拉色菌培养阳性率以及菌种构成比较差异均无显著性意义,菌种存在一致性,但一致性较差。结论马拉色菌是患儿皮肤的常驻菌;脂溢性皮炎患儿及正常婴儿皮肤马拉色菌可能部分来源于母亲。

Investigation of Malassezla Furfur Bacteria Carrier of Infantile Head and Fcial Dermatitis Seborrheica

Objective To survey malassezia furfur bacteria carrier and source in infant suffered dermatitis seborrheica on head/facial and healthy.Methods Using tape amethod to adhibit squama and dandruff from the heads and faces of infant patients breast of and their mother,the forehead skin of the healthy and breast of otheir mother,then inoculate rapeseed oil media fostering epiphyte to separate malassezia furfur bacteria and identify the bacteria by using the method of physiology and biochemistry as well as morphology.Results ①We obtained 101 malassezia furfur bacteria by separate 150 specimens among 4 groups.②There was no remarkable difference between the positive rate and bacterial constitution related the suffered and healthy children;③There was no remarkable difference between the positive rate and bacterial constitution related the suffered and healthy children and their corresponding mother.Coherence analysis corresponding bacteria had consistency but the consistency was poor.Conclusion Malassezia furfur bacteria is a pathogenic microbes;Malassezia furfur bacteria of Infantile skin of suffered children dermatitis seborrheica may origin partly from its mother and Malassezia furfur bacteria carried by healthy children may origin partly from its mother too.
