gram-negative
(redirected from Gram-negative bacterial infections)

   Also found in: Dictionary/thesaurus, Encyclopedia, Wikipedia 0.01 sec.
gram-negative /gram-neg·a·tive/ (-neg´ah-tiv) losing the stain or decolorized by alcohol in Gram's method of staining, characteristic of bacteria having a cell wall surface more complex in chemical composition than the gram-positive bacteria.
gram-negative or Gram-negative
adj.
Of, relating to, or being a bacterium that does not retain the violet stain used in Gram's method.

Gram-negative
Refers to the property of many bacteria that causes them to not take up color with Gram's stain, a method which is used to identify bacteria. Gram-positive bacteria which take up the stain turn purple, while Gram-negative bacteria which do not take up the stain turn red.

gram-negative
Etymology: Hans C.J. Gram, Danish physician, 1853-1938; L, negare, to say no
having the pink color of the counterstain used in Gram's method of staining microorganisms. This property is a primary method of characterizing organisms in microbiology. Some of the most common gram-negative pathogenic bacteria are Bacteroides fragilis, Brucella abortus, Escherichia coli, Haemophilus influenzae, Klebsiella pneumoniae, Neisseria gonorrhoeae, Proteus vulgaris, Pseudomonas aeruginosa, Salmonella typhi, Shigella dysenteriae, and Yersinia pestis.

gram-negative [gram-neg´ah-tiv]
losing the stain or decolorized by alcohol in Gram's method of staining; see Gram stain. This is a primary characteristic of bacteria having a cell wall composed of a thin layer of peptidoglycan covered by an outer membrane of lipoprotein and lipopolysaccharide.

gram-negative,
n having the pink color of the counterstain used in Gram's method of staining microorganisms. Staining property is a common method of classifying bacteria. See also Gram's stain.

gram-negative
said of bacteria that are decolorized by alcohol in Gram's method of staining (see gram's stain), and are thus stained only with the counter stain (usually red). Gram-negative bacteria have a much thinner layer of peptidoglycan in the cell wall than Gram-positive bacteria.

The drug is currently also being studied in a second complicated skin infection trial (STRAUSS II) targeting both Gram-positive and Gram-negative bacterial infections, including patients with diabetic foot infections; and in phase III clinical trials in nosocomial pneumonia (CHOPIN studies) and in patients hospitalized with community-acquired pneumonia.
Discovered by Toyama Chemical, T-3811 is a new type of broad-spectrum quinolone antibiotic for treating Gram-positive and Gram-negative bacterial infections.
About MDR Gram-negative infections Multidrug-resistant Gram-negative bacterial infections are an area of significant unmet medical need, particularly in acute care settings.
