Aeromonas species are gram-negative anaerobic rods found in fresh water lakes and streams. They have also been recovered from chlorinated tap water, including hospital water supplies. Aeromonas infections of freshwater traumatic wounds cause a characteristic clinical picture indistinguishable from group A streptococcal infection in normal hosts ...

Non-fermentative Gram-negative bacteria
International Journal of Antimicrobial Agents, 2007Over the past decade, non-fermenting Gram-negative bacteria have emerged as important opportunistic pathogens in the increasing population of patients who are immunocompromised by their disease or medical treatment. These bacteria are assisted by their ubiquitous distribution in the environment and have a propensity for multiple, intrinsic or acquired ...

The cell wall of Gram-negative bacteria has a very distinctive layered look under the electron microscope and is dramatically different from the Gram-positive cell wall. The inner layer consists of a thin peptidoglycan layer; the outer layer or outer membrane is a protein containing bilayer.

Leukotoxins of gram-negative bacteria
Veterinary Microbiology, 2002Leukotoxins are a group of exotoxins that produce their primary toxic effects against leukocytes, especially polymorphonuclear cells (PMNs). Leukotoxins include a variety of chemicals ranging from 9,10-epoxy 12-octadecenoate, a fatty acid derivative secreted by leukocytes themselves, to proteins such as RTX (repeats in toxin).

Antibiotic uptake into gram-negative bacteria
European Journal of Clinical Microbiology & Infectious Diseases, 1988Antibiotics taken up into gram-negative bacteria face two major diffusion barriers, the outer and cytoplasmic membranes. Of these, the former has been most studied and is discussed in detail here. Evidence from antibiotic MIC studies on porin-deficient mutants compared with their porin-sufficient parent strains has provided strong support for the ...

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.
