Abstract

A single-nucleotide polymorphism-based cluster grouping (SCG) classification system for Mycobacterium tuberculosis was used to examine antibiotic resistance type and resistance mutations in relationship to specific evolutionary lineages. Drug resistance and resistance mutations were seen across all SCGs. SCG-2 had higher proportions of katG codon 315 mutations and resistance to four drugs.

摘要

一种基于单核苷酸多态性的结核分枝杆菌聚类分组(SCG)分类系统被用于研究抗生素耐药类型以及与特定进化谱系相关的耐药突变。在所有SCG中均发现了耐药性和耐药突变。SCG-2中katG密码子315突变以及对四种药物耐药的比例更高。
