Epidemiology of pharyngeal colonization of infants with aerobic gram-negative rod bacteria

open access: bronzeJournal of Clinical Microbiology, 1989
By using a selective medium, pharyngeal colonization with gram-negative rod (GNR) bacteria was determined in a cohort of 49 normal infants monitored from birth to 6 months of age. Culture swabs were diluted in 1 ml of saline for quantitation. The prevalence of GNR in the first 72 h of life was 8% and rose to 29% during the first month, 52% at 2.5 ...

Comparative in vitro antibacterial activity of seven semi-synthetic penicillins against aerobic gram-negative bacteria and enterococci

open access: closedInfection, 1982
The MICs and MBCs of mecillinam, ticarcillin, mezlocillin, azlocillin and piperacillin were determined by the microdilution method in liquid medium using 700 strains of gram-negative bacilli and enterococci isolated from pathological sources and classified as a function of their sensitivity to ampicillin and carbenicillin.

Family Spirosomaceae: Gram-Negative Ring-Forming Aerobic Bacteria [PDF]

open access: possibleCritical Reviews in Microbiology, 1990
The bacteria having a unique ring-like morphology first isolated from nasal mucus by Weibel in 1887 were classified as a new genus Spirosoma by Migula in 1894. However, because these bacteria were not completely described for taxonomic purposes and their cultures were no longer available, the genus was deleted from the Bergey's Manual of Determinative ...

Imipenem Resistance in Aerobic Gram-Negative Bacteria

Journal of Chemotherapy, 1998
A prospective study was undertaken to observe the emergence of resistance to imipenem, if any, among aerobic gram-negative bacteria. A total of 736 isolates were tested during 1994-95 and less than 1% of them were resistant to imipenem, whereas the next year ('95-'96) the rate increased to 11 of the 903 isolates tested.

Identification of Aerobic Gram-Negative Bacteria

2008
This chapter addresses the Gram stain and cellular morphology of bacteria, which are key features for preliminary identification of the Gram-negative genera. Reference laboratories may utilize mass spectrometry or polymerase chain reaction assays to assist in the identification of aerobic Gram-negative bacteria.Additionally, 16S rRNA gene sequence ...

Occurrence of Poly-β-Hydroxybutyric Acid in Aerobic Gram-Negative Bacteria

Nature, 1958
DURING an examination of the metabolic products of an unidentified purple-pigmented pseudomonad, a fraction, soluble in chloroform and insoluble in ether, was found to comprise 30 per cent of the dry cell weight. The material was isolated as a colourless solid, m.p.
