Association between 16S-23S internal transcribed spacer sequence groups of Mycobacterium avium complex and pulmonary disease.
Organisms within the Mycobacterium avium complex (MAC) may have differential virulence. We compared 33 subjects with MAC pulmonary disease to 75 subjects with a single positive culture without disease. M. avium isolates were significantly more likely to be associated with MAC pulmonary disease (odds ratio = 5.14, 95% confidence interval = 1.25 to 22.73) than M. intracellulare.
متن کاملDifferential Identification of Flavobacterium Species by Sequence Analysis of Genus-Specific Hypervariable 16S-23S rDNA Intergenic Spacer Target
The aim of the current study was to develop a molecular system for differential identification of various fish diseases caused by Flavobacterium species. The system uses the hypervariability of the 16S-23S rDNA Intergenic spacer region (ISR) to develop PCR-based sequence analysis assay. For this purpose, eight different 16S-23S rDNA ISR sequences of six different Flavobacterium species were ali...
متن کاملMolecular Assessment of 16S-23S rDNA Internal Transcribed Spacer Length Polymorphism of Aeromonas hydrophila
Aeromonas hydrophila is an important bacterial pathogen which causes the hemorrhagic septicemia in fishes, amphibians and humans. Genetic relationships of diverse isolates of A. hydrophila were recovered from fish and water sources. These isolates were investigated by flanked region of 16S and 23S Ribosomal DNA (rDNA) internal transcribed spacer (ITS). Here we analyzed polymorphism of PCR-ampli...
متن کامل16S rRNA and 16S to 23S internal transcribed spacer sequence analyses reveal inter- and intraspecific Bifidobacterium phylogeny.
In the last few years many attempts have been made to differentiate more than 20 Bifidobacterium species. It has been recognized that identification of bifidobacterial species is problematic because of phenetic and genetic heterogeneities. In order to contribute to our understanding of Bifidobacterium taxonomy, we studied Bifidobacterium phylogeny by performing both 16S rRNA and 16S to 23S (16S...
متن کاملMolecular Identification of Rare Clinical Mycobacteria by Application of 16S-23S Spacer Region Sequencing
Objective(s) In addition to several molecular methods and in particular 16S rDNA analysis, the application of a more discriminatory genetic marker, i.e., 16S-23S internal transcribed spacer gene sequence has had a great impact on identification and classification of mycobacteria. In the current study we aimed to apply this sequencing power to conclusive identification of some Iranian clinical ...
