Gram stain

  • They have no cell wall and therefore do not Gram stain.
  • This reliable Gram stain technique is now being used throughout the world.
  • Gram-stain/smear becomes important in identification of rare and possibly more serious organisms.
  • Additional tests will be performed if indicated such as microbiological culture, Gram stain and cytopathology.
  • Along with cell shape, Gram staining is a rapid method used to differentiate bacterial species.
  • Alternative commonly followed subdivision systems were based on Gram stains.
  • The specific antimicrobial agent should be chosen based on Gram stain and culture, or on local epidemiologic data when these are not available.
  • There is no connection between the shape of a bacterium and its colors in the Gram staining.
  • Normally, if Gram stain is done on acid-fast bacteria, they show up as if they are gram-positive, mostly because of their thick cell wall.
  • In addition, in all bacteria stained using the Gram stain, the age of the culture may influence the results of the stain.
  • Atypical bacteria are those species of bacteria that do not color with gram-staining but rather remain colorless.
  • Actinomycetes can hardly be distinguished from bacteria at its early stages because of how much they resemble bacteria in size, shape and gram-staining properties.
  • Gram staining is also less reliable in particular infections such as listeriosis.
  • Gram stains are performed on body fluid or biopsy when infection is suspected.
  • To help with diagnosis, a synovial fluid Gram stain and culture may be performed.
  • Older detection kits, based on latex agglutination, added little value above Gram staining and were occasionally false-positive.
  • The Gram stain is almost always the first step in the identification of a bacterial organism.
  • These acids resist staining by ordinary methods such as a Gram stain.
  • This technique, the Gram stain, continues to be a standard procedure in medical microbiology.
  • Test results must be interpreted in conjunction with gram stain morphology.
