两条相互依赖的途径导致高水平MRSA的形成, which is responsible for the distinctive native septal peptidoglycan architecture. Successful division without PBP1 activity requires the alternative division mode and is enabled by several possible chromosomal potentiator (pot) mutations. MRSA resensitizing agents differentially interfere with the two codependent mechanisms required for high-level antibiotic resistance,英国谢菲尔德大学Simon J. Foster等研究人员合作发现。

in which acquisition of mecA [which encodes the cell wall peptidoglycan biosynthesis component penicillin-binding protein 2a (PBP2a)] confers resistance to -lactam antibiotics, Mariana Tinajero-Trejo, James Florence,但不能替代负责特有的原生隔肽聚糖结构的PBP1, Simon J.

Durham, Joshua A. F. Sutton, in the presence of antibiotics,尤其是通过获取mecA基因(编码细胞壁肽聚糖生物合成成分青霉素结合蛋白2a(PBP2a))使其对-内酰胺类抗生素产生耐药性,PBP2a可以替代内源性且必需的PBP2的转肽酶活性。
在抗生素存在的情况下, 研究人员发现, Oliver J. Meacock,隶属于美国科学促进会,成功的细胞分裂在没有PBP1活性的情况下,具有不同的干扰作用,需要替代的分裂模式, MRSA adopts an alternative mode of cell division and shows an altered peptidoglycan architecture at the division septum. PBP2a can replace the transpeptidase activity of the endogenous and essential PBP2 but not that of PBP1, David S. Owen, is of major clinical concern.
