A team of researchers at the University of California, Los Angeles (UCLA) has introduced a virtual Gram staining technique that could transform how microbiologists stain and classify bacteria ...

Staining of Bb spirochetes was positive in infected mouse liver samples. There was no significant Bb immunostaining of the Bb-negative mouse liver control, the mixed Gram-positive bacterial pellet ...

Compared with other methods, urine Gram stain moderately predicted gram-negative bacteria but added little value to UTI diagnosis in the ED, raising questions about its clinical utility.

Gram-positive bacteria have thicker cell walls that retain the purple color from Gram stain, which can quickly differentiate cell types based on the width of their cell walls.

Influential scientist Hans Christian Gram left a durable mark on microbiology thanks to the pioneering staining technique he invented – and he’s now being celebrated with a Google Doodle on ...

Gram-positive bacteria are bacteria that contain a thick cell wall. During the Gram staining process — a test that experts use to view the bacteria under a microscope — they appear purple or blue.

The Journal of Infectious Diseases, Vol. 34, No. 2 (Feb., 1924), pp. 105-109 (5 pages) Acetone, or iodine and acetone, serves as a superior decolorizer in the acid-fast stain as in the Gram stain. The ...

Hans Christian Gram, the inventor of the Gram staining technique, was a pioneering biologist who devised the system of classification which led to as many as 30,000 formally named species of ...

The Gram stain is almost always the first step in the preliminary identification of a bacterial organism. Gram was then appointed a professor of medicine at the University of Copenhagen in 1900.

I show here that by staining plates with crystal violet or methylene blue, the zone of inhibition can be not only more clearly visible but also easily photographed. Barely visible zone of ...
