在大阪,抗宏化物耐药的 Mycoplasma pneumoniae (M. pneumoniae) 正在增加. 大多数耐药菌株表现出一种特定的基因突变,与高水平的化物耐药性有关.
科学领域:
- 微生物学 微生物学
- 传染性疾病 传染性疾病
- 分子生物学分子生物学
背景情况:
- 菌性肺炎是呼吸道感染的常见原因.
- 宏类抗生素是M. pneumoniae感染的主要治疗方法.
- 在M. pneumoniae中出现宏类耐药性的出现构成了重大的公共卫生挑战.
研究的目的:
- 为了确定抗化物耐药的M. pneumoniae菌株的流行率.
- 为了研究M. pneumoniae.的耐药机制.
- 从2018年到2024年,追踪宏类耐药性的趋势.
主要方法:
- 对367名患有M. pneumoniae感染的患者的分析.
- 使用聚合酶链反应 (PCR) 进行菌株鉴定.
- 检查了M. pneumoniae 23S rRNA基因的耐药性突变.
主要成果:
- 与2018年至2020年相比,2024年化物耐药M. pneumoniae的流行率显著增加 (60.2%).
- 观察到阻力显著增加,特别是在2024年.
- 在23S rRNA基因的2063位置的A到G过渡是主要的抗性机制,赋予了高水平的抗性.
结论:
- 在大阪府,抗宏化物耐药的M. pneumoniae的患病率正在增加.
- 确定的基因突变与宏类抗药性密切相关.
- 持续监测M. pneumoniae中宏类耐药性的情况至关重要.
