肺炎链球菌荚膜对于疾病的发病机制至关重要,这表明即使是肺炎链球菌基因座内微小的遗传变化也可能产生重要的后果。阿伦兹等人。 (D. W. Arends、W. R. Miellet、J. D. Langereis、T. H. A. Ederveen 等人,Infect Immun 89:e00246-21, 2021,https://doi.org/10.1128/IAI.00246-21)已鉴定出 79 种不同的非同义单核苷酸多态性 (SNP)研究人员对 338 个 19A 血清型菌株的 cps 位点进行了分析,并显示菌株之间的核苷酸糖含量和荚膜脱落存在显着差异。需要进一步的工作来表征这些变化是否对胶囊-宿主相互作用产生重要的功能影响。
The Streptococcus pneumoniae capsule is essential for disease pathogenesis, suggesting that even minor genetic changes within thecpslocus could potentially have important consequences. Arends et al. (D. W. Arends, W. R. Miellet, J. D. Langereis, T. H. A. Ederveen, et al., Infect Immun 89:e00246-21, 2021, https://doi.org/10.1128/IAI.00246-21) have identified 79 different nonsynonymous single-nucleotide polymorphisms (SNPs) in thecpslocus of 338 19A serotype strains and shown significant variations between strains in nucleotide sugar content and capsule shedding. Further work is required to characterize whether any of these changes have important functional consequences on capsule-host interactions.
