空肠弯曲菌是一种重要的人畜共患病病原菌,其耐药性问题一直是公众关注的焦点。然而,很少有研究调查了整个生物体在抗生素耐药性方面的全球变化。在这里,我们提供了机制的见解,高水平的耐药性氯霉素在C。空肠,使用整合的基因组和蛋白质组学分析。我们确定了27个单核苷酸多态性(SNP)以及一个外排泵cmeB突变,赋予适度的耐药性。我们确定了两个自由基S-腺苷甲硫氨酸(SAM)酶,每个SNP基因和差异表达的蛋白质。主要代谢途径的验证表明氧化磷酸化和ABC转运蛋白的改变,表明能量积累和蛋氨酸输入增加。总的来说,我们的数据揭示了一种新的rRNA甲基化机制的自由基SAM超家族酶,表明两种耐药机制存在于弯曲杆菌。这项工作为理解细菌的抗生素耐药性机制提供了系统生物学视角。
Campylobacter jejuni is a major zoonotic pathogen, and its resistance to antibiotics is of great concern for public health. However, few studies have investigated the global changes of the entire organism with respect to antibiotic resistance. Here, we provide mechanistic insights into high-level resistance to chloramphenicol in C. jejuni, using integrated genomic and proteomic analyses. We identified 27 single nucleotide polymorphisms (SNPs) as well as an efflux pump cmeB mutation that conferred modest resistance. We determined two radical S-adenosylmethionine (SAM) enzymes, one each from an SNP gene and a differentially expressed protein. Validation of major metabolic pathways demonstrated alterations in oxidative phosphorylation and ABC transporters, suggesting energy accumulation and increase in methionine import. Collectively, our data revealed a novel rRNA methylation mechanism by a radical SAM superfamily enzyme, indicating that two resistance mechanisms existed in Campylobacter. This work provided a systems biology perspective on understanding the antibiotic resistance mechanisms in bacteria.
