Analysis for a limited number of gene codons can predict drug resistance of Mycobacterium tuberculosis in a high-incidence community
Correct and rapid diagnosis is essential in the management of multidrug-resistant tuberculosis (MDR-TB). In this population-based study of 61 patients with drug-resistant tuberculosis, we evaluated the frequency of mutations ...
Sequence polymorphism in the rrs gene of Mycobacterium tuberculosis is deeply rooted within an evolutionary clade and is not associated with streptomycin resistance
A mutation (C-to-T transition) at position 491 of the rrs gene was identified in a Mycobacterium tuberculosis strain family (n = 208 isolates) that was predominant in a suburb of Cape Town, South Africa. This nucleotide ...
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 ...
Calculation of the stability of the IS6110 banding pattern in patients with persistent Mycobacterium tuberculosis disease
The interpretation of molecular epidemiologic data of Mycobacterium tuberculosis infection is dependent on the understanding of the stability and evolutionary characteristics of the DNA fingerprinting marker used to classify ...
Stability of Polymorphic GC-Rich Repeat Sequence-Containing Regions of Mycobacterium tuberculosis
Mycobacterium tuberculosis cultures were subjected to DNA fingerprinting with IS6110- and polymorphic GC-rich sequence (PGRS)-containing probes. The PGRS banding patterns remained highly stable during multiple cultures of ...
Evolution of the IS6110-based restriction fragment length polymorphism pattern during the transmission of Mycobacterium tuberculosis
Interpretation of the molecular epidemiological data of Mycobacterium tuberculosis is dependent on the validity of the assumptions that have been made. It is assumed that the IS6110 banding pattern is sufficiently stable ...
Evaluation of the Capilia TB assay for culture confirmation of Mycobacterium tuberculosis infections in Zambia and South Africa
The performance and cost of the Capilia TB assay were evaluated for use in a resource-limited setting. The sensitivity and specificity were 99.6% and 99.5%, respectively. The incremental costs of the Capilia test were ...
Decline in total serum IgE after treatment for tuberculosis
Background. Infection with Mycobacterium tuberculosis induces a type-1 immune response, whereas intestinal parasites elicit a type-2 response. Given that type-1 and type-2 responses inhibit each other, we investigated if ...
The fourth I: Scaling up implementation of collaborative TB-HIV activities to protect vulnerable mothers and infants
