BACKGROUND Investigation of genetic heterogeneity and spoligotype-defined lineages of drug-resistant Mycobacterium tuberculosis clinical isolates collected during a three-year period in two university hospitals and National Tuberculosis Reference and Research Laboratory in Ankara, Turkey. METHODS AND FINDINGS A total of 95 drug-resistant M. tuberculosis isolates collected from three different...
BACKGROUND Tuberculosis notification rates for London have risen dramatically in recent years. Molecular typing of Mycobacterium tuberculosis has contributed to our understanding of the epidemiology of tuberculosis throughout the world. This study aimed to assess the degree of recent transmission of M tuberculosis in London and subpopulations of the community with high rates of recent transmiss...
BACKGROUND Relapse of tuberculosis (TB) may develop as the result of reactivation of the endogenous primary infection, or as a result of a exogenous reinfection. This survey evaluated the rate of reactivation versus recent transmission among Iranian and Afghan relapse cases. METHODS The sputum specimens were digested, examined microscopically for acid-fast bacilli, and inoculated into Löwenst...
BACKGROUND The identification and differentiation of strains of Mycobacterium tuberculosis by DNA fingerprinting has provided a better understanding of the epidemiology and tracing the transmission of tuberculosis. We set out to determine if there was a relationship between the risk of belonging to a group of tuberculosis patients with identical mycobacterial DNA fingerprint patterns and the HI...
OBJECTIVES To compare M. tuberculosis complex genotypes from representative regions of the Czech Republic in order to estimate changes in strain prevalence and in the extent of imported drug-resistant tuberculosis. METHODS Primary M. tuberculosis complex isolates (n=155) and follow-up isolates (n=15) from 155 patients from the first half of 2004 (98 from Prague, 37 from South Moravia and 35 f...
BACKGROUND From 2003 through to 2004, an outbreak of tuberculosis was identified at a university campus in Yokohama City, located in the southern part of the Tokyo Metropolitan Area (TMA). All Mycobacterium tuberculosis (M. tuberculosis) strains detected with regards to this outbreak turned out to be Streptomycin resistant with matched patterns of 14 IS6110 bands of Restriction Fragment Length ...
Molecular markers provide an important method for detecting tuberculosis (TB) transmission that has been followed by rapid progression to active disease. Restriction fragment length polymorphism (RFLP) typing of Mycobacterium tuberculosis has been used to confirm outbreaks, through the demonstration of shared isolates. In population-based studies, it has therefore been inferred that patients wi...
Tuberculosis (TB) remains a deadly infectious disease affecting millions of people worldwide; 95% of TB cases, with 98% of death occur in developing countries. The situation in South Africa merits special attention. A total of 21,913 sputum specimens of suspected TB patients from three provinces of South Africa routinely submitted to the TB laboratory of Dr. George Mukhari (DGM) Hospital were a...
