Abstract

In a 2-year prospective study of tuberculosis (TB) patients in China, the prevalences of non-Beijing strains of Mycobacterium tuberculosis varied between Shandong Province (20.6%), Shanghai (27.6%), and Sichuan Province (45.9%) (P < 0.005). These differences may be due to factors such as human migration, transmission, or diversification and adaptation of the mycobacteria to different hosts.

Number of isolates with non-Beijing family strains of M. tuberculosis in three different geographical areas, by sublineages, from 1 December 2006 to 31 December 2008. The major sublineages of non-Beijing strains detected in the study were T1 and T2, which can be found on most continents in the world. “Unclassified” includes a group of strains with spoligotyping patterns that were not classified in SpolDB4.
