Immunity Targeting Common Core Antigens of Gram-Negative Bacteria

Antibiotic Resistance Pattern of Gram-Negative Bacteria in Gorgan

Abstract Background and Objective: The excessive use of broad-spectrum antibiotics will lead to drug resistance of microorganism and specially nosocomial organisms. Because of high incidence of antibiotic resistance in hospitals, we aimed to study antibiotic resistance to gram negative bacteria. Material and Methods: This cross-sectional study was conducted on the data of biological sampl...

Isolation of Gram-negative Bacteria

Three different areas -hospital, food-handling establishments and human dwellings, were surveyed for pathogenic gram-negative bacteria carried on the cuticles of cockroaches. Fifty species of bacteria were identified from all cockroaches. Escherichia coli, Klebsiella pneumoniae, Citrobacter freundii and Enterobacter cloacae were the most frequently found. Pathogenic and potentially pathogenic b...

Synthesis and Characterization of Novel Antibacterial PDDA/Honey Nanofiber Against Gram-Positive and Gram-Negative Bacteria

Nanomaterials are increasingly used to the targeting of gram-positive and gram-negative bacteria as an alternative to antibiotics. Bacterial infections are a major cause of chronic infections and mortality. People requirement for new materials for pathogenic bacteria treatment. It seems that nanomaterial-based strategies can be resolving this problem. In this research, improved antibacterial na...

Role of N-acetylglucosamine within core lipopolysaccharide of several species of gram-negative bacteria in targeting the DC-SIGN (CD209).

Our recent studies have shown that the dendritic cell-specific ICAM nonintegrin CD209 (DC-SIGN) specifically binds to the core LPS of Escherichia coli K12 (E. coli), promoting bacterial adherence and phagocytosis. In this current study, we attempted to map the sites within the core LPS that are directly involved in LPS-DC-SIGN interaction. We took advantage of four sets of well-defined core LPS...
