BACKGROUND Data on the performance of standardized short-course directly observed treatment (DOTS) of tuberculosis (TB) in areas with high levels of drug resistance and on the potential impact of DOTS on amplification of resistance are limited. Therefore, we analyzed treatment results from a cross-sectional sample of patients with TB enrolled in a DOTS program in an area with high levels of dru...
OBJECTIVE To compare drug resistance (DR) rates and genetic diversity of Mycobacterium tuberculosis strains from different states of Mexico. MATERIALS AND METHODS A systematic review of English and Spanish-language articles using MEDLINE and Google Scholar. Search terms included Mycobacterium tuberculosis, Mexico, resistance, mutation and epidemiology. RESULTS Fifteen studies for phenotypic...
In recent years, Klebsiella pneumoniae strains have become the second largest bacteria after the E. coli in China causing community-acquired infections and nosocomial infection [1]. The K. pneumoniae strains commonly recognized by clinicians and microbiologists are termed classic K. pneumoniae (cKP). Such strains are notorious for their capacity to cause nosocomial infections Detection and Anal...
SETTING Israel receives migrants from various countries, some of which have high tuberculosis (TB) prevalence. OBJECTIVE To assess the predominant Mycobacterium tuberculosis strains in Israel isolated during 2008-2010 among Israeli-born and migrant patients, and to investigate possible transmission of TB from migrants to the local population. METHODS Molecular characterisation employed 43-s...
Mycobacterium tuberculosis, the causative agent of most human tuberculosis, infects one third of the world's population and kills an estimated 1.7 million people a year. With the world-wide emergence of drug resistance, and the finding of more functional genetic diversity than previously expected, there is a renewed interest in understanding the forces driving genome evolution of this important...

Tuberculosis now exceeds HIV as the top infectious disease cause of mortality, and is caused by the Mycobacterium tuberculosis complex (MTBC). MTBC strains have highly conserved genome sequences (similarity >99%) but dramatically different phenotypes. To analyze the relationship between genotype and phenotype, we conducted the comparative genomic analysis on 12 MTBC strains representing differe...
The N and W-Beijing families of Mycobacterium tuberculosis are phylogenetically closely related. The ability of the W-Beijing family to rapidly cause widespread disease is well described; however, few outbreaks involving the N family have been reported outside the New York City, N.Y., area. During 2002 to 2003, Seattle, Wash., experienced a rapidly expanding tuberculosis outbreak involving 38 p...
