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...

coastal region of chah bahar port, sea of oman, was screened for the presence of bioluminescence bacteria for the first time. water samples were taken from surface and subsurface layers and immediately spread on nutrient seawater complete (swc) agar. luminous colonies were observed after an overnight incubation at 25°c. among twenty luminous isolates, four of them were selected for preliminary ...

in this research the effects of crude oil on morphological and physiological characterization ofthe cyanobacterium microchaete tenera isc13 were investigated. isolated cyanobacterium treated with different oil concentrations (control, 1, 2.5, 5 and 7%) in carbonless bg110 medium. morphological characteristics such as morphology of filament, cellular shapes and sizes, relative position of hetero...
