肺炎支原体肺炎对大环内酯类药物耐药研究进展

近年来肺炎支原体对大环内酯类药物的耐药现象越来越多,目前认为其耐药机制与药物结合位点的基因突变、核糖体甲基化、药物的主动外排和药物灭活有关,其中以药物作用靶位23SrRNA基因2063、2064位点突变为主.有研究报道,耐药患者对大环内酯类药物治疗的效果较差,表现为总热程长、换药率高.对耐药患者的治疗,大多数研究仍然采...

Study on Macrolide resistance of mycoplasma pneumoninae

In recent years,more and more Macrolide resistance of Mycoplasma pneumoniae becomes a hot research.The current studies suggest that the mechanisms of Macrolide resistance are drug-binding site mutations,ribosome methylation,drug efflux,and drug related fire-fighting,in which the drug target 23srRNA gene 2063,2064 mutation is significant.It has been reported that drug-resistant patients have the poor effect,including the long total febrile days and high dressing.For treatment of drug-resistant patients,most studies still use the macrolide,early use of corticosteroids may be effective.It is uncertain whether the increase in resistant strains is related with the use of macrolide.It is significant to carry out future researches in this area for clinical therapy and put off the prevalence of drug-resistant strains.
