After staining we are able to classify bacteria into 2 categories; Gram-Positive & Gram-Negative. Which dyes/ stains are used for gram … Both Gram-positive and Gram-negative bacteria commonly have a surface layer called an S-layer. In Gram-positive bacteria the S-layer is attached to the peptidoglycan layer. Gram-negative bacteria's S-layer is attached directly to the outer membrane). Specific to Gram-positive bacteria is the presence of teichoic acids in the cell wall. Some of these … Gram stain or Gram staining also called Gram's method is a method of staining used to distinguish and classify bacterial species into two large groups (gram-positive and gram-negative). The name comes from the Danish bacteriologist Hans Christian Gram who developed the technique. Both gram-positive and gram-negative bacteria can be pathogenic (see list of pathogenic bacteria ). Six gram-positive genera of bacteria are known to cause disease in humans: Streptococcus Staphylococcus Corynebacterium Listeria Bacillus and Clostridium. Thu Sep 11 2008 00:00:00 GMT+0530 (IST) · Gram-positive bacteria have a thick mesh-like cell wall made of peptidoglycan (50-90% of cell wall) which stain purple and Gram-negative bacteria have a thinner layer (10% of cell wall) which stain pink. Gram-negative bacteria also have an additional outer membrane which contains lipids and is separated from the cell wall … If your doctor suspects you have an infection they may order a culture and gram stain to check for bacteria.

The difference is the outer casing of the bacteria . A gram ... Inherent variability in organism Gram characteristics: Certain organisms do not always exhibit expected Gram stain characteristics; occasionally Gram-positive organisms will appear Gram-negative and Gram-negative organisms retain crystal violet during the destaining step and appear Gram-positive (Table 20.1). Gram positive bacteria stain violet due to the presence of a thick layer of peptidoglycan in their cell walls which retains the crystal violet these cells are stained with. Alternatively Gram negative bacteria stain red which is attributed to a thinner peptidoglycan wall which does not retain the crystal violet during the decoloring process. Gram-negative bacteria Staphylococcus aureus Bacteria
