    • The present disclosure relates to method for detecting P. acnes as well as a method for detecting mutation in genomic sequence of 23S rRNA sequence of P. acnes, particularly mutation A2058G. The method comprises amplifying a region of 23S rRNA specific for P. acnes using primers of SEQ ID Nos. 1 and 2 followed by detecting the mutation through selective action of an endonuclease at a mismatch at the site of said mutation or post-hybridization with specific P. acnes 23S regions followed by mismatch specific endonuclease action. The presence of A2058G mutation confers antibiotic resistance, particularly clindamycin and erythromycin resistance, and thus the present disclosure also relates to methods of treating acne caused by clindamycin resistant P. acnes by using fluoroquinolone based antibiotics.
    • 本发明涉及用于检测痤疮丙酸杆菌的方法以及用于检测痤疮丙酸杆菌的23S rRNA序列的基因组序列中的突变,特别是突变A2058G的突变的方法。 该方法包括使用SEQ ID Nos.1和2的引物扩增痤疮丙酸杆菌特异性的23S rRNA区域,然后通过在所述突变位点处的错配或与特异性后杂交后的内切核酸酶的选择性作用检测突变 痤疮丙酸杆菌23S区域,然后是错配特异性核酸内切酶作用。 A2058G突变的存在赋予抗生素抗性,特别是克林霉素和红霉素抗性,因此本公开还涉及通过使用基于氟喹诺酮的抗生素来治疗由克林霉素抗性痤疮丙酸杆菌引起的痤疮的方法。
