Mycobacterium tuberculosis complex genetic diversity: mining the fourth international spoligotyping database (SpolDB4) for classification, population genetics and epidemiology
BackgroundThe Direct Repeat locus of the Mycobacterium tuberculosis complex (MTC) is a member of the CRISPR (Clustered regularly interspaced short palindromic repeats) sequences family. SpoligotypingExpand
Impact of Genotypic Studies on Mycobacterial Taxonomy: the New Mycobacteria of the 1990s

  • 1 April 2003
SUMMARY The advancement of genetic techniques has greatly boosted taxonomic studies in recent years. Within the genus Mycobacterium, 42 new species have been detected since 1990, most of which wereExpand
The geographic diversity of nontuberculous mycobacteria isolated from pulmonary samples: an NTM-NET collaborative study
A significant knowledge gap exists concerning the geographical distribution of nontuberculous mycobacteria (NTM) isolation worldwide. To provide a snapshot of NTM species distribution, globalExpand
Clinical validation of Xpert MTB/RIF for the diagnosis of extrapulmonary tuberculosis
Extrapulmonary tuberculosis (EPTB) accounts for more than 20% of tuberculosis (TB) cases. Xpert MTB/RIF (Xpert) (Cepheid, Sunnyvale, CA, USA) is a fully automated amplification system, for whichExpand

  • 1 October 2014
SUMMARY Nontuberculous mycobacteria (NTM) are present in the environment, mainly in water, and are occasionally responsible for opportunistic infections in humans. Despite the fact that NTM areExpand
Identification of 54 Mycobacterial Species by PCR-Restriction Fragment Length Polymorphism Analysis of the hsp65Gene
ABSTRACT A total of 121 reference and clinical strains of both slowly and rapidly growing mycobacteria belonging to 54 species were studied for restriction fragment length polymorphism of aExpand
Proposal to elevate the genetic variant MAC-A, included in the Mycobacterium avium complex, to species rank as Mycobacterium chimaera sp. nov.
The possibility that the strains included within the Mycobacterium avium complex (MAC), but not belonging either to M. avium or to Mycobacterium intracellulare, may be members of undescribed taxa,Expand
Heterogeneity and clonality among isolates of Mycobacterium kansasii: implications for epidemiological and pathogenicity studies.
The reservoir and transmission route of Mycobacterium kansasii are largely unknown. In addition, culturing of M. kansasii from human sources is not proof of disease because it may representExpand
Mycobacterium colombiense sp. nov., a novel member of the Mycobacterium avium complex and description of MAC-X as a new ITS genetic variant.
Forty-five mycobacterial strains isolated from 23 Colombian HIV-positive patients were identified as members of the Mycobacterium avium complex (MAC) and were characterized using different molecularExpand
Rapid molecular TB diagnosis: evidence, policy making and global implementation of Xpert MTB/RIF
If tuberculosis (TB) is to be eliminated as a global health problem in the foreseeable future, improved detection of patients, earlier diagnosis and timely identification of rifampicin resistanceExpand
