Definition

adjective

Of, or relating to that group of bacteria that retain the violet stain following Gram's method


Supplement

The term gram-positive is used to link to a group of bacteria that retains the violet colour stain through Gram's method. Bacteria that retain the colour violet after gram staining are referred to as gram-positive in contrast to those that stain pink. The latter group is described as gram-negative. Gram staining is an important staining technique used in identifying whether the bacterial species causing the disease is gram-positive or gram-negative. This information can be used to determine the kind of treatment that is effective in treating a disease or infection.

The term gram-positive is also used to describe the kind of bacteremia; bacteremia that involves gram-positive bacteria is referred to as gram-positive bacteremia.
