early diagnosis of bacteremia and its complications is the most important part of care and management of the febrile patients. however, a majority of patients who appear to be clinically septic have negative blood culture. the use of polymerase chain reaction (pcr) techniques has allowed identifying the pathogenic organisms rapidly and accurately. the objective of this study was to investigate ...

it is difficult to distinguish between clinically significant slowly-growing, non-pigmented mycobacteria, notably to separate m. aviumand m. intracellulare from one another and from m. scrofulaceum strains. the purpose of this study was to evaluate the extent to which 16s rrna sequencing could be used to highlight the taxonomic relationships of the mycobacterial strains, which are difficult to ...

Introduction: Helicobacter pylori (H. pylori), is a bacterium responsible for upper gastrointestinal tract diseases. The 16s rRNA is a common H. pylori gene which are usually preferred for diagnosis purpose. The aim of this study was to determine the prevalence and abundance of 16s rRNA in fecal samples and also evaluate correlation between the level of 16s rRNA and activities of the cytokine...

The aim of this study was to compare published Helicobacter pylori primer pairs for their ability to reliably detect H. pylori in gastric biopsy specimens and salivary samples. Detection limits of the 26 PCR primer pairs previously described for detection of H. pylori DNA in clinical samples were determined. Sensitivity and specificity were determined using primers with detection limits of <100...
