helicobacter pylori infection, the most common chronic bacterial infection in the world, and an important cause of gastrointestinal disorders, may be involved in the pathogenesis of some extra-gastrointestinal disturbances, as well as an increase in blood levels of certain inflammatory markers. anti-bacterial activity against helicobacter pylori and anti-inflammatory properties of omega-3 fatty...

PyroSmart NextGen® is a recombinant cascade reagent (rCR) for the detection and quantification of bacterial endotoxins developed using cloned genes derived from Limulus polyphemus horseshoe crab genome. Requirements use this alternative include analysis analytical performance, method suitability, test result equivalency to amoebocyte lysate (LAL) reagents used in compendial Bacterial Endotoxins...

ubiquicidin (ubi) [29-41] is a synthetic cationic antimicrobial peptide that preferentially binds to bacterial cell membrane at the site of infection. we aimed to assess diagnostic value of 99mtc-ubi [29-41] as a radiopharmaceutical in differentiation of bacterial infection from sterile inflammation in suspected orthopedic implants. nine patients suspected for orthopedic implant infection, all ...

Acute sinusitis is very common in children and can be classified as bacterial or viral depending on the etiology. The diagnosis of acute sinusitis in children should be based on the presence of clinical findings that are suggestive of acute sinusitis rather than on imaging findings. The diagnosis can be confirmed by performing a culture and sensitivity test of the paranasal discharge. Once the ...

The sensitivity of a polA strain to the antibacterial activity of mutagens and carcinogens may be increased by inserting one or both of the following characteristics, a lexA mutation or the R391 bacterial plasmid. The effects of the lexA mutation and the plasmid appear to be additive. The differential sensitivity of a polA lexA (R391) strain could be adapted as a preliminary screening test for ...

The climate sensitivity of microbe-mediated soil processes such as carbon and nitrogen cycling offers an interesting case for evaluating the corresponding sensitivity of microbial community composition to environmental change. Better understanding of the degree of linkage between functional and compositional stability would contribute to ongoing efforts to build mechanistic models aiming at pre...

OBJECTIVE To monitor the bacterial load in newborns with proven infections on the day of admission, 48 h and 7 days after treatment. METHODS Real-time PCR (qPCR) targeting the 16S rDNA. RESULTS The study recruited 17 newborns and the bacterial load was in general low (<50 CFU/mL). In three of four deaths, the bacterial load values increased, and in 11 of the 13 survivors the values decrease...

BACKGROUND Despite the implementation of prevention guidelines, early-onset group B streptococci (GBS) disease remains a cause of neonatal morbidity and mortality worldwide. Strategies to identify women who are at risk of transmitting GBS to their infant and the administration of intrapartum antibiotics have greatly reduced the incidence of neonatal GBS disease. However, there is a requirement ...

BACKGROUND The diagnostic value of procalcitonin (PCT) for patients with renal impairment is unclear. METHODS We searched multiple databases for studies published through December 2011 that evaluated the diagnostic performance of PCT among patients with renal impairment and suspected systemic bacterial infection. We summarized test performance characteristics with the use of forest plots, hie...

background: bacteremia due to enterococcus faecalis is usually caused by strains resistant to most antibiotics. effective management of the disease is dependent on rapid detection and characterization of the bacteria, and determination its sensitivity pattern to antimicrobial drugs. the aim of this study was to investigate a more rapid and reliable assay for simultaneous diagnosis of enterococc...
