In Vitro Activities of Membrane-Active Peptides against Gram-Positive and Gram-Negative Aerobic Bacteria [PDF]

Antimicrobial Agents and Chemotherapy, 1998
ABSTRACT Four peptides, cecropin P1, magainin II, indolicidin, and ranalexin, were evaluated against 202 clinical isolates of gram-positive and gram-negative aerobic bacteria by a microbroth dilution method. The gram-negative isolates were more susceptible to cecropin P1.

Species distribution and antimicrobial susceptibility of gram-negative aerobic bacteria in hospitalized cancer patients [PDF]

Journal of Translational Medicine, 2009
Nosocomial infections pose significant threats to hospitalized patients, especially the immunocompromised ones, such as cancer patients.This study examined the microbial spectrum of gram-negative bacteria in various infection sites in patients with leukemia and solid tumors.

Gram-positive and Gram-negative bacteria elicit different patterns of pro-inflammatory cytokines in human monocytes

Cytokine, 2005
Pro-inflammatory cytokines secreted by tissue macrophages recruit polymorphonuclear leukocytes and evoke fever, cachexia and production of acute phase proteins.

A Probability Matrix for the Identification of Gram-negative, Aerobic, Non-fermentative Bacteria that Grow on Nutrient Agar

Microbiology (United Kingdom), 1986
Results of the identification of 621 strains of Gram-negative, aerobic, non-fermentative bacteria by a computer-based probabilistic method are given. Although many of the strains were atypical and have caused difficulty in identification in the medical diagnostic laboratory, the identification rate on this matrix was 91.5%.

Poplar Lignin Decomposition by Gram-Negative Aerobic Bacteria [PDF]

Applied and Environmental Microbiology, 1981
Eleven gram-negative aerobic bacteria ( Pseudomonadaceae and Neisseriaceae ) out of 122 soil isolates were selected for their ability to assimilate poplar dioxane lignin without a cosubstrate. Dioxane lignin and milled wood lignin degradation rates ranged between 20 and 40% of initial content

In vitro activity of ciprofloxacin against aerobic gram-negative bacteria [PDF]

Antimicrobial Agents and Chemotherapy, 1984
For 177 gram-negative isolates, the MICs for ciprofloxacin ranged from 0.02 microgram/ml (Escherichia coli) to 0.31 microgram/ml (Pseudomonas aeruginosa). In time-kill curves, ciprofloxacin at 8 X the MIC almost completely killed 10(6) CFU of P. aeruginosa by 24 h.

Detection of alternative nitrogenases in aerobic gram-negative nitrogen-fixing bacteria [PDF]

Journal of Bacteriology, 1991
Strains of aerobic, microaerobic, nonsymbiotic, and symbiotic dinitrogen-fixing bacteria were screened for the presence of alternative nitrogenase (N2ase) genes by DNA hybridization between genomic DNA and DNA encoding structural genes for components 1 of three different enzymes.
