What is the importance of gram staining?

Answer 1

Gram staining (or Gram's method) is an empirical method of differentiating bacterial species into two large groups (Gram-positive and Gram-negative) based on the chemical and physical properties of their cell walls. It is a first step to determine the identity of a particular bacterial sample. Gram stains are performed on body fluid or biopsy when infection is suspected. It yields results much more quickly than culture, and is especially important when infection would make an important difference in the patient's treatment and prognosis.

Answer 2

It allows you to observe the morphology of the bacteria under a microscope. Identification can be established due to the shape of configuration of the bacteria. You should be aware though that bacteria can exhibit many forms and it is only the most predominate one you need to assess. Colonies can divide in one plane and form linear, chain like patterns, in two planes or at right angles forming tetards or can even divide randomly forming grape like clusters.

Answer 3

Gram staining is used to differentiate between those bacteria that have an outer membrane and those that do not. Gram positive bacteria do not have an outer membrane and will appear purple/violet when stained. Gram negative bacteria contain an outer membrane and will appear red/pink when stained

not expenseve

very helpfull for destinguish between the bacteria

Answer 5

The gram staining procedure is important in medicine because it is a typical way to distinguish different types of bacteria. Gram stain-positive generally are staph or strep bacteria.
