Select Gram-negative Aerobic Bacteria

2012
Gram-negative bacteria may be rod-shaped (bacilli), spherical (cocci), oval, helical, or filamentous. Cytoplasmic membrane is surrounded by a cell wall consisting of a peptidoglycan layer and an outer cell membrane. Gram-negative bacteria are widely distributed in the natural environment.

Family Spirosomaceae: Gram-Negative Ring-Forming Aerobic Bacteria

Critical 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 ...

Gram-Negative, Aerobic, Nitrilotriacetate-Utilizing Bacteria from Wastewater and Soil

Systematic and Applied Microbiology, 1988
Summary Nine Gram-negative strains and one Gram-positive strain of obligately aerobic, nitrilotriacetate (NTA)-utilizing bacteria were isolated from wastewater and soil. They were characterised with respect to their substrate utilization pattern, various physiological properties, DNA base ratio and quinone types, and were compared with the two NTA ...

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.

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 ...

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

Journal 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 ...

Characteristics of Aerobic Gram-negative Bacteria Colonizing Critically III Patients

American Review of Respiratory Disease, 1991
Abstract Adherence of gram-negative bacteria (GNB) to epithelial surfaces is important for GNB colonization to occur. Pili, rodlike structures projecting from the outer membrane of GNB, and GNB surface hydrophobicity have been shown to enhance GNB adherence.

A Simple Scheme for Identification of Aerobic Gram-Negative Bacteria with Special Reference to Enterobacteriaceae

Zentralblatt für Veterinärmedizin Reihe B, 2010
ummary A scheme using six biochemical reactions, followed in some cases by one or two additional tests, is described for the identification of gram-negative aerobic bacteria belonging to 20 genera that could grow on Mac Conkey agar incubated at 37°C.

Infections Caused by Miscellaneous Gram-Negative Aerobic Bacteria

1988
Cardiobacterium hominis, formerly called CDC group lid, is a rare cause of subacute bacterial endocarditis. The organism inhabits the upper respiratory tract in man and has been detected in 68% of healthy individuals (Slotnick et al., 1964). Carriage appears to be unrelated to the age or sex of the individual, and antibody against C.
