Extensively Drug-Resistant Tuberculosis, Pakistan

摘要

Frequency of extensively drug-resistant tuberculosis in Pakistan increased from 1.5% in 2006 to 4.5% in 2009 (p<0.01). To understand the epidemiology, we genotyped selected strains by using spoligotyping, mycobacterial in-terspersed repetitive units–variable number of tandem re-peats, and IS6110restriction fragment length polymorphism analysis
