In contrast to our findings in Vietnam (2), Prodinger et al. found no significant association between the Beijing genotype and either young age or drug resistance (1). However, we have some caveats regarding the comparison of these two studies. First, we restricted our analysis to newly diagnosed patients to avoid confounding by possible d...

Mycobacterium tuberculosis Beijing genotype, northern Malawi.(Dispatches)
Emerging Infectious Diseases ; In a 7-year population-based study in Malawi, we showed that Beijing genotype tuberculosis (TB) increased as a proportion of TB cases. All the Beijing genotype strains were fully drug sensitive. Contact histories, TB type, and case-fatality rates were similar for Beijing and non-Beijing genotype

Emerging Infectious Diseases ; DNA fingerprinting has demonstrated predominance of the Beijing genotype among Mycobacterium tuberculosis strains isolated in Southeast Asia. We prospectively examined the occurrence of Beijing genotype strains in tuberculosis patients in Indonesia. Early in treatment, patients infected with
Mycobacterium tuberculosis Beijing Genotype Emerging in Vietnam.(Statistical Data Included)
Emerging Infectious Diseases ; To assess whether the Mycobacterium tuberculosis Beijing genotype is emerging in Vietnam, we analyzed 563 isolates from new cases by spoligotyping and examined the association between the genotype and age, resistance, and BCG vaccination status. Three hundred one (54%) patients were infected with
Mycobacterium tuberculosis Beijing genotype, the Netherlands.(Dispatches)
Emerging Infectious Diseases ; To determine whether the Beijing genotype of Mycobacterium tuberculosis is emerging in the Netherlands, we collected data on 6,829 patients during 1993 to 2000. Six percent had the Beijing genotype. This genotype was associated with diagnosis in recent years, young age, nationality, and multidrug
Beijing/W genotype Mycobacterium tuberculosis and drug resistance: European Concerted Action on New Generation Genetic Markers and Techniques for the Epidemiology and Control of Tuberculosis * (1).
Emerging Infectious Diseases ; Beijing/W genotype Mycobacterium tuberculosis is widespread, may be increasing, and may have a predilection for drug resistance. Individual-level data on >29,000 patients from 49 studies in 35 countries were combined to assess the Beijing genotype's prevalence worldwide, trends over time and
