Lysis of gram-negative bacteria by serum.
The antibacterial property of serum, first reported by Nuttall in 1888, has attracted many investigators and an extensive literature has accumulated. The sera of most mammals tested have been found to possess bactericidal activity, but a notable exception is the mouse, whose serum, apparently through lack of complement, is unable to kill any of a number of bacterial strains which are sensitive ...
متن کاملAntibiotic 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...
متن کاملTransferrin-iron uptake by Gram-negative bacteria.
Members of the families Neisseriaceae, Pasteurellaceae and Moraxellaceae are capable of transferrin-iron acquisition in the absence of siderophore production. They do so via expression of a bi-partite receptor composed of two dissimilar proteins, TbpA and TbpB. Both proteins are surface exposed, iron-regulated and capable of binding transferrin. However, other physiochemical, antigenic, and imm...
متن کاملIsolation 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...
متن کاملSynthesis 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...
