纤毛菌属中的颊纤毛菌,是含铁的细菌,属于口腔的条件致病菌。粘膜上皮营养障碍,特别是角化和过度角化区,为纤毛菌病的发展造成最适宜的条件。纤毛菌长期寄生在粘膜上,可侵入粘膜下组织,甚至导致纤毛菌性脓毒症的发生。为查明颊纤毛菌对口腔粘膜病的病因学作用,进行临床和细菌镜检155例,其中24例无主诉(对照组)。131例主诉口腔不适,临床确诊纤毛菌病。对照组从舌和颊粘膜各区取材,粘膜病变组从病灶 Mycobacterium genus in the genus, is iron-containing bacteria, oral conditions are pathogenic bacteria. Mucosal dystrophy, especially keratinization and hyperkeratosis, create the most appropriate conditions for the development of the mycosis. Long-term parasitic on the mucosa, can invade the submucosal tissue, and even lead to the occurrence of ciliated sexually transmitted sepsis. In order to find out the etiological role of Mycobacterium bucali on oral mucosal disease, clinical and bacterial microscopic examination of 155 cases, of which 24 cases without complaint (control group). 131 cases complained of oral discomfort, clinical diagnosis of ciliated mycosis. Control group from the tongue and buccal mucosa drawn from the lesion, mucosal lesions from the lesion
