EARLY PREDICTION OF GRAM-POSITIVE BACTEREMIA IN FEVERISH EGYPTIAN PATIENTS USING SOME SELECTED INFLAMMATORY MEDIATORS [PDF]

Al-Azhar Journal of Pharmaceutical Sciences, 2015
Bloodstream infection is an important cause of morbidity and mortality. Some components of the bacterial cell wall bind to receptors on the cell surface of the host monocytes and macrophages and induce cytokines production. This study assessed the levels

Multidrug-Resistant Gram-Positive Bacterial Infections

Korean Journal of Medicine, 2015
Antimicrobial resistance threatens the effective treatment of bacterial infections and is a serious problem worldwide. Multidrug-resistant bacteria are difficult to treat and the treatment outcome is worse than with susceptible bacteria. In Korea, the antibiotic resistance rates of the major Gram-positive bacteria methicillin-resistant Staphylococcus ...

Prevalence and Antibiotic Resistance Pattern of Gram-Positive Isolates from Burn Patients in Velayat Burn Center in Rasht, North of Iran

Medical Laboratory Journal, 2021
Background and objectives: Bacterial contamination of wounds is a serious problem, particularly in burn patients. Gram-positive bacteria are the predominant cause of infection in newly hospitalized burn cases.

Biofilm-Related Infections in Gram-Positive Bacteria and the Potential Role of the Long-Acting Agent Dalbavancin

Frontiers in Microbiology, 2021
Infections caused by Gram-positive bacteria are a major public health problem due to their increasing resistance to antibiotics. Staphylococcus and Enterococcus species’ resistance and pathogenicity are enhanced by their ability to form biofilm.

Gram-positive bacterial lipoglycans based on a glycosylated diacylglycerol lipid anchor are microbe-associated molecular patterns recognized by TLR2 [PDF]

, 2013
Innate immune recognition is the first line of host defense against invading microorganisms. It is a based on the detection, by pattern recognition receptors (PRRs), of invariant molecular signatures that are unique to microorganisms.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

FEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Dynamic Profiling of Lipoteichoic Acid (LTA) and/or Lipopolysaccharide (LPS) Positive Extracellular Vesicles in Plasma as Diagnostic and Prognostic Biomarkers for Bacterial Infection

Advanced Science
Bacterial extracellular vesicles (EVs) are emerging as promising biomarkers for diagnosing bacterial infections. This study explores the diagnostic potential of plasma EVs carrying bacterial lipopolysaccharide (LPS) or lipoteichoic acid (LTA).
