Gram-negative bacteria are responsible for a broad array of infections in both the ambulatory and hospital settings. Urinary tract infections, otitis media, pneumonia, abdominal infections, and meningitis are among the common and serious diseases caused by these pathogens. Beta-lactams including penicillins, cephalosporins, monobactams, and carbapenems,

Isolating DNA from Gram-Negative Bacteria
Cold Spring Harbor Protocols, 2017The isolation of DNA from bacteria, described in this protocol, relies upon the use of sodium dodecyl sulfate and proteinase K to lyse the cells. High-molecular-weight DNA is then sheared (to reduce its viscosity and make it more manageable), extracted with phenol:chloroform, and precipitated with isopropanol.

Resistance in gram-negative bacteria: Enterobacteriaceae
American Journal of Infection Control, 2006The emergence and spread of resistance in Enterobacteriaceae are complicating the treatment of serious nosocomial infections and threatening to create species resistant to all currently available agents. Approximately 20% of Klebsiella pneumoniae infections and 31% of Enterobacter spp infections in intensive care units in the United States now involve ...

Gram-negative brewery bacteria
2003Brewing bacteriology was born when microorganisms responsible for the spoilage of beer were investigated by Lotus Pasteur in his classic nineteenth- century study. He was called upon to determine why French beer was inferior to German beer. He isolated a number of bacterial contaminants from French beer and malt wort and in 1876 published his famous ...

Emerging Gram-negative bacteria
Current Opinion in Pulmonary Medicine, 2018The current review examines the current literature around 'emerging' Gram-negative bacteria other than Pseudomonas aeruginosa in cystic fibrosis (CF), paying particular focus on the recent literature for those that are more frequently encountered: Pandoraea, Achromobacter, Ralstonia and Stenotrophomonas species.The recent literature is evolving our ...

Corneal Rings With Gram-Negative Bacteria
Archives of Ophthalmology, 1977Corneal rings have been described with corneal ulcerations caused by Gram-negative bacteria. Corneal rings were produced by intracorneal injections of viable Pseudomonas aeruginosa as well as heat-inactivated suspensions of Gram-negative bacteria (P aeruginosa and Escherichia coli) but not Gram-positive bacteria (Staphylococcus aureus) or Freund's ...

Solvent tolerance in Gram-negative bacteria
Current Opinion in Biotechnology, 2012Bacteria have been found in all niches explored on Earth, their ubiquity derives from their enormous metabolic diversity and their capacity to adapt to changes in the environment. Some bacterial strains are able to thrive in the presence of high concentrations of toxic organic chemicals, such as aromatic compounds, aliphatic alcohols and solvents.

Three lactobacilli strains were examined for the inhibitory activity against some gram-negative bacteria with a comparison of well diffusion and spot on lawn method. The inhibitory activity of lactobacilli under spot on lawn method showed significant clear zones. Although in spot on lawn method, lactobacilli have strongest antagonistic activity against

Polysaccharides of Gram-Negative Bacteria
1961Publisher Summary This chapter discusses the polysaccharides of gram-negative bacteria. In Gram-negative bacteria, the general architecture of the outer layers of the cell seems to be consistent within the group. The cell wall is rarely exposed, but is generally covered by a somatic antigen’ that can be extracted as a protein-lipide-polysaccharide ...
