13. A molecular and epidemiological based-work system for detection of bovine tuberculosis focus in the state of São Paulo / Sistema de detecção de focos de tuberculose bovina no Estado de São Paulo utilizando métodos moleculares e epidemiológicos
A partnership between the Department of Preventive Veterinary Medicine and Animal Health (VPS) of the FMVZ-USP, the Coordination of Agriculture and Animal Defense of the State of São Paulo, and the Federal Inspection Service (SIF) was established to organize a work system for detection of bovine tuberculosis focus in the state, based on routine methods of c

15. Use of Mycobacterial Interspersed Repetitive Unit-Variable-Number Tandem Repeat Typing To Examine Genetic Diversity of Mycobacterium tuberculosis in Singapore
Strain typing using variable-number tandem repeats of mycobacterial interspersed repetitive units (MIRU-VNTR) is a powerful tool for studying the epidemiology and genetic relationships of Mycobacterium tuberculosis isolates. For this study, isolates from 291 patients in Singapore were genotyped by this method. One hundred sixty-six distinct MIRU-VNTR pattern

16. Sensitivities and Specificities of Spoligotyping and Mycobacterial Interspersed Repetitive Unit-Variable-Number Tandem Repeat Typing Methods for Studying Molecular Epidemiology of Tuberculosis
The development of PCR-based genotyping modalities (spoligotyping and mycobacterial interspersed repetitive unit-variable-number tandem repeat [MIRU-VNTR] typing) offers promise for real-time molecular epidemiological studies of tuberculosis (TB). However, the utility of these methods depends on their capacity to appropriately classify isolates. To determine

17. Automated High-Throughput Mycobacterial Interspersed Repetitive Unit Typing of Mycobacterium tuberculosis Strains by a Combination of PCR and Nondenaturing High-Performance Liquid Chromatography
Mycobacterial interspersed repetitive unit-variable number tandem repeat (MIRU-VNTR) typing of Mycobacterium tuberculosis complex isolates is portable, 100% reproducible, and highly discriminatory. Nondenaturing high-performance liquid chromatography (non-dHPLC) with use of a WAVE microbial analysis system is a promising method of PCR amplicon analysis as it

18. Evaluation of the Epidemiologic Utility of Secondary Typing Methods for Differentiation of Mycobacterium tuberculosis Isolates
Spoligotyping and mycobacterial interspersed repetitive unit-variable-number tandem repeat analysis (MIRU-VNTR) were evaluated for the ability to differentiate 64 Mycobacterium tuberculosis isolates from 10 IS6110-defined clusters. MIRU-VNTR performed slightly better than spoligotyping in reducing the number of clustered isolates and the sizes of the cluster

19. Characterization of Ancestral Mycobacterium tuberculosis by Multiple Genetic Markers and Proposal of Genotyping Strategy
Sixty-eight ancestral Mycobacterium tuberculosis isolates were previously identified by using the tuberculosis-specific deletion 1 (TbD1) PCR and mycobacterial interspersed-repetitive-unit-variable-number tandem repeat (MIRU-VNTR) typing (Y.

20. Mycobacterial Interspersed Repetitive Unit Typing of Mycobacterium tuberculosis Compared to IS6110-Based Restriction Fragment Length Polymorphism Analysis for Investigation of Apparently Clustered Cases of Tuberculosis
An evaluation of the utility of IS6110-based restriction fragment length polymorphism (RFLP) typing compared to a combination of variable number tandem repeat (VNTR) typing and mycobacterial interspersed repetitive unit (MIRU) typing was undertaken. A total of 53 patient isolates of Mycobacterium tuberculosis from four presumed episodes of cross-infection we

21. High-resolution minisatellite-based typing as a portable approach to global analysis of Mycobacterium tuberculosis molecular epidemiology
The worldwide threat of tuberculosis to human health emphasizes the need to develop novel approaches to a global epidemiological surveillance. The current standard for Mycobacterium tuberculosis typing based on IS6110 restriction fragment length polymorphism (RFLP) suffers from the difficulty of comparing data between independent laboratories. Here, we

22. Genotypic Analysis of Mycobacterium tuberculosis in Bangladesh and Prevalence of the Beijing Strain
Genotypic analysis was performed on 48 Mycobacterium tuberculosis complex strains collected from a hospital in Dhaka city. Deletion analysis showed that the isolates were all M. tuberculosis; 13 of them were found to be of the “ancestral” type, while 35 were of the “modern” type, indicating that both endemic (ancestral type) and epidemic (modern type

23. Variable-Number Tandem Repeat Typing of Mycobacterium tuberculosis Isolates with Low Copy Numbers of IS6110 by Using Mycobacterial Interspersed Repetitive Units
A study set of 180 Mycobacterium tuberculosis and Mycobacterium bovis isolates having low copy numbers of IS6110 were genotyped using the recently introduced method based on the variable-number tandem repeats of mycobacterial interspersed repetitive units (MIRU-VNTR). The results were compared with results of the more commonly used methods, IS6110 restrictio

24. Stability of Variable-Number Tandem Repeats of Mycobacterial Interspersed Repetitive Units from 12 Loci in Serial Isolates of Mycobacterium tuberculosis
Variable number tandem repeats (VNTRs) of elements named mycobacterial interspersed repetitive units (MIRUs) have previously been identified in 12 minisatellite loci of the Mycobacterium tuberculosis genome. These markers allow reliable high-throughput genotyping of M. tuberculosis and represent a portable approach to global molecular epidemiology of M. tube
