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

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

Evaluation of Cathra system for identifying gram negative aerobic bacteria. [PDF]
The Cathra system is a commercial multipoint inoculation method for the identification of aerobic Gram negative bacteria. The system uses a replicator technique in which 21 different agar media can be inoculated simultaneously with 36 organisms. Identifications are made by use of a special computer database.

Effect of High Oxygen Tensions on the Growth of Selected, Aerobic, Gram-negative, Pathogenic Bacteria [PDF]
The in vitro effects of high O 2 tensions (P O 2 ) on aerobic, enteric pathogens were examined at pressures of up to 3 atm absolute. Organisms from the genera Salmonella, Shigella , and Vibrio were ...

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

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

A Revised Probability Matrix for the Identification of Gram-negative, Aerobic, Rod-shaped, Fermentative Bacteria [PDF]
The results of the identification of 933 strains of Gram-negative, aerobic, rod-shaped, fermentative bacteria (Enterobacteriaceae, Pasteurellaceae, Vibrionaceae) by a probabilistic method, in a computer, are given. The identification rate on the matrix was 89.2%.

Increase of Antimicrobial Resistance of Faecal Aerobic Gram-negative Bacteria in a Geriatric Hospital [PDF]
Antimicrobial resistance of faecal aerobic Gram-negative bacteria to eight different antimicrobials was determined by a velvet replica-plating method in 1988 and 1933. Faecal samples were taken from 131 geriatric inpatients in the Turku City Hospital with a hospitalization of more than 7 days.

Mesophilic aerobic Gram negative cellulose degrading bacteria from aquatic habitats and soils [PDF]
New procedures have been developed for the isolation and purification of aerobic and facultatively anaerobic bacteria able to utilize cellulose as sole source of carbon and energy. Wood pulp medium was used for enrichment, and bacterial cellulose, obtained from cultures of Acetobacter aceti subsp.
