Bacteria are divided into two groups based on how their cell walls absorb?
Bacteria are divided into two groups based on how their cell walls absorb the Gram stain. Gram-positive bacteria retain the stain due to their thick peptidoglycan cell wall, while Gram-negative bacteria do not retain the stain because of their thin peptidoglycan cell wall and an outer membrane.
Does the gram stain procedure work for all bacteria?
Yes. The gram stain procedure separates all bacteria into one of two groups - into gram-negative bacteria which do not stain purple and into gram-positive cells which do stain purple. In structural terms, the ability of a cell to become stained during the gram stain procedure is due to the chemical makeup of the cell wall.
Why isn't the Gram stain used on acid-fast bacteria?
The Gram stain is not effective on acid-fast bacteria because their cell walls have a waxy layer that prevents the stain from penetrating.
Do acid-fast bacteria stain gram-negative when subjected to the gram stain?
No, acid-fast bacteria do not stain gram-negative when subjected to the gram stain.
What are the differences between the Gram stain and acid-fast stain techniques in microbiology?
The Gram stain technique is used to differentiate bacteria into two groups based on their cell wall composition (Gram-positive and Gram-negative), while the acid-fast stain technique is used to detect bacteria that have a waxy cell wall, such as Mycobacterium species.

What is the Gram stain for measles?
Bacteria stain either gram-positive or gram-negative based on the presence or absence of a cell wall. Viruses do not pick up a gram stain.
What does gram negative on a serratia marcescens gram stain mean?
Bacteria are gram positive or gram negative. Serratia happens to be a gram negative bacteria. They appear pink on a gram stain. Gram positive bacteria stain to a purple color on a gram stain. We can classify and ID bacteria using their gram stain and shape. Some antibiotics only work on gram negative bacteria and some only work on gram positive bacteria. It helps a doctor know which antibiotic to use.
Why isn't the Gram stain used on acid-fast bacteria?
The Gram stain is not effective on acid-fast bacteria because their cell walls have a waxy layer that prevents the stain from penetrating.
What is the difference between gram-positive and gram-negative bacteria?
The presence of thick cell wall. Gram positives have a thick cell wall and remain blue. Gram negatives have a thin cell wall where the blue stain washes out and then will stain pink with the counter stain.
Do acid-fast bacteria stain gram-negative when subjected to the gram stain?
No, acid-fast bacteria do not stain gram-negative when subjected to the gram stain.
What is the difference between gram plus and?
Gram positive bacteria stain purple with the Gram stain. This is because of the fact that they contain a thick layer of murein in their cell wall, which takes up the stain very well. Gram negative bacteria, however, do not display the thick layer of peptidoglycan on their outer surface. Therefore, they stain red with the counter stain.
What stain is used to distinguish differences between the cell walls of medically important bacteria?
Gram stain is commonly used to distinguish differences between the cell walls of medically important bacteria. This technique categorizes bacteria into Gram-positive (purple) and Gram-negative (pink) based on their cell wall structure, aiding in identification and classification of bacteria in microbiology.
What are the differences between the Gram stain and acid-fast stain techniques in microbiology?
The Gram stain technique is used to differentiate bacteria into two groups based on their cell wall composition (Gram-positive and Gram-negative), while the acid-fast stain technique is used to detect bacteria that have a waxy cell wall, such as Mycobacterium species.
What are the uses of the gram stain technique scientifically speaking?
Gram stains are used to analyze bacteria and determine their characteristics. The most popular use of a gram stain is to determine the thickness of a cell wall in bacteria.
Which thing make gram positive bacteria to get stain?
the smooth part of the cell wall make it to get stain
