脂溢性皮炎的病因学研究—糠秕孢子菌与脂溢性皮炎的关系

ETIOLOGICAL INVESTIGATION ON SEBORRHEIC DERMATITIS____THE RELATION BETWEEN PITYROSPORUM AND SEBORRHEIC DERMATITIS

本文报告在57例脂溢性皮炎患者的头皮屑中培养出园形和卵园形糠秕孢子菌,培养阳性率为94.7%。菌落生长缓慢,外观为乳白色酵母样,本菌嗜油性,米粉吐温80玻片培养不产生菌丝,血清培养不产生芽管,同化试验无生长和利用。

In this paper, we report that pityrosporum o biculare or/and pityrosporum ovale were cultivated from dandruff of 57 patients with seborrheic dermatitis. The posi-tivity rate was 94.7% in our series.The colony grows slowly and appears cream colour, yeastlike and oleophilic. It did not engender hyphae in Rice-Tween 80 medium and did not produce germ tubes in scrum culture. It could not grow and could not utilize carbohydrate in CHO assimilation test and was neither acidogenic nor aerogenous in fermentation test
