Characteristics of Aerobic Gram-negative Bacteria Colonizing Critically III Patients

American Review of Respiratory Disease, 1991
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.

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.

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 ...

The Physiology and Biochemistry of Aerobic Methanol-Utilizing Gram-Negative and Gram-Positive Bacteria [PDF]

, 1992
One-carbon compounds (C1) at all oxidation levels between methane and carbon dioxide occur abundantly throughout nature. Methane is present in fossil deposits and is formed by methanogenic bacteria. Methanol arises by the hydrolysis of methyl esters and ethers such as pectin and lignin, which are present in plants. Methylated amines occur in plants and

Can beta-lactamase resistance genes in anaerobic Gram-negative gut bacteria transfer to gut aerobes?

The Journal of Antibiotics, 2023
The study was conceived with the hypothesis that human aerobic gut flora could act as a reservoir of ß-lactamases and contribute to the emergence of ß-lactam resistance by transferring ß-lactamase genes to resident anaerobes. Thus, we studied the repertoire of ß-lactam resistance determinants (ß-lactamases associated with aerobes and anaerobes) in Gram-

Bloodgroup simulating activity in aerobic gram-negative oral bacteria cultured from fresh corpses

Forensic Science International, 1991
The gram-negative aerobic oral bacterial flora of 100 consecutive corpses was isolated. After the identification and culturing of the isolated organisms, blood grouping was performed by the haemagglutination inhibition technique on dried culture smears, the dried culture medium and a dried ethanol extract of the bacteria.

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.
