A virtual staining neural network model converts darkfield images of label-free bacteria into Gram-stained equivalents with brightfield contrast, bypassing the manual steps involved in chemical ...

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 ...

If the test results from your sputum Gram’s stain are abnormal, it means that bacteria and white blood cells have been detected. The bacteria found will be Gram-positive or Gram-negative.

Published by Hans Christian Gram in 1884, gram staining distinguishes gram-positive bacteria (purple) from gram-negative bacteria (pink). Gram-positive critters, such as staph, have a thick ...

As gram positive bacteria lack an outer lipid membrane, when correctly referring to their structure rather than staining properties, are termed monoderms. The outer lipid membrane possessed by gram ...
