Compared with other urine analysis methods, urine Gram stain has a moderate predictive value for detecting gram-negative bacteria in urine culture but does not significantly improve urinary tract ...

Similar outcomes in patients with ventilator-associated pneumonia (VAP) suggest that antibiotics selected by Gram staining were noninferior to those based on guidelines and also significantly ...

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.

Gram staining is one way scientists can identify bacteria. Gram-positive bacteria, such as Staphylococcus, appear blue or purple under a microscope when scientists apply a stain. Conversely ...

Being a cationic dye, crystal violet can be used to stain negatively charged polymers such as DNA 18 and cell walls of bacteria, the latter of which is partially the basis of Gram staining to ...

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 ...

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.

Gram is best known for pioneering the method of the Gram stain to identify bacteria. The Danish microbiologist earned an M.D. from the University of Copenhagen in 1878. He then traveled through ...
