Replacing reverse line blot hybridization spoligotyping of the Mycobacterium tuberculosis complex.
Spoligotyping is a tool for the molecular characterization/typing of Mycobacterium tuberculosis complex (MTBC) strains based on target sequences (spacers) in the direct repeat (DR) region (14). The standard spoligotyping assay involves the hybridization of amplified sample DNA to nylon membrane-immobilized oligonucleotides whose sequences are representative of 43 spacer regions. Variations in t...
متن کاملTransfer of a Mycobacterium tuberculosis genotyping method, Spoligotyping, from a reverse line-blot hybridization, membrane-based assay to the Luminex multianalyte profiling system.
Spoligotyping using Luminex technology was shown to be a highly reproducible method suitable for high-throughput analysis. Spoligotyping of 48 isolates using the traditional membrane-based assay and the Luminex assay yielded concordant results for all isolates. The Luminex platform provides greater flexibility and cost effectiveness than the membrane-based assay.
متن کاملSpoligotyping and Mycobacterium tuberculosis
We evaluated the clinical usefulness of spoligotyping, a polymerase chain reaction-based method for simultaneous detection and typing of Mycobacterium tuberculosis strains, with acid-fast bacilli-positive slides from clinical specimens or mycobacterial cultures. Overall sensitivity and specificity were 97% and 95% for the detection of M. tuberculosis and 98% and 96% when used with clinical spec...
متن کاملRapid detection of rifampin-resistant clinical isolates of Mycobacterium tuberculosis by reverse dot blot hybridization.
OBJECTIVE A PCR-reverse dot blot hybridization (RDBH) assay was developed for rapid detection of rpoB gene mutations in 'hot mutation region' of Mycobacterium tuberculosis (M. tuberculosis). METHODS 12 oligonucleotide probes based on the wild-type and mutant genotype rpoB sequences of M. tuberculosis were designed to screen the most frequent wild-type and mutant genotypes for diagnosing RIF r...
متن کاملMultiplex PCR and Reverse Line Blot Hybridization Assay (mPCR/RLB)
Multiplex PCR/Reverse Line Blot Hybridization assay allows the detection of up to 43 molecular targets in 43 samples using one multiplex PCR reaction followed by probe hybridization on a nylon membrane, which is re-usable. Probes are 5' amine modified to allow fixation to the membrane. Primers are 5' biotin modified which allows detection of hybridized PCR products using streptavidin-peroxidase...
