Acid-fast and Gram stain are two different types of staining technique. Bacteria that stain with acid-fast techniques are called "acid fast bacteria." Bacteria that don't stain with acid-fast techniques are called "not acid fast." At the same time, bacteria can be "Gram-positive" or "Gram-negative." For example, Nocardia is a bacterium that is acid-fast and Gram-positive. Usually the reason people care about these designations is in order to figure out what species a bacteria is. The issue usually arises in the context of a patient's sample that has grown bacteria. At first the doctors won't be sure which bacteria it is. They'll have guesses based on how the patient presented, but they won't know, and they want to know because that will help them pick the best treatment. A first step toward "speciating" the bacteria is to do a Gram stain on it. This is because for historical reasons determining whether a bacteria is Gram-positive or Gram-negative goes a long way toward speciating it. Acid-fast staining is less common, and is used mostly for diagnosing tuberculosis (caused by Mycobacteria, which are acid-fast bacteria). There are details about the cell walls that determine whether an organism will stain with Gram stain (thick walls without mycolic acids) or acid-fast, but hopefully this answers your question.

Is klebsiella gram positive or negative?
i believe it is a gram bacteria which causes respiratory illness.
Is lactobacillus casei is a gram negative bacteria or gram positive?
The Bacteria Sarcina lutea is Gram Positive Because If You Perform the Gram Test It Will Turn The Violet Color Which indicates It's Positiveness. What Makes It Positive Is the Peptidoglycan Located Within The The Bacterium
Is proteus gram positive or gram negative?
It's an Gram - ve bacteria.
A drug that inhibits mitosis such as griseofulvin would be more effective against a. Fungi. b. Gram-positive bacteria c. Mycobacteria d. Wall-less bacteria e. Gram-negative bacteria?
a. fungi
Is Staphylococcus saprophyticus gram positive or negative?
Yes. Staphylococci are classified as gram positive bacteria and appear as purple spheres when Gram stained.
Why is important to distinguish between Gram-positive and Gram-negative bacteria in diagnosing a bacterial infection?
gram- negative and gram- positive bacteria differ in their response to different antibiotics
How many type of bacterias you have?
there are two different types of bacteria 1) gram positive bacteria 2) gram negative bacteria these two bacteria differ in the peptidoglycon layer which constitutes the cell membrane
Is klebsiella gram positive or negative?
i believe it is a gram bacteria which causes respiratory illness.
Which type of bacteria are present in curd either gram plus ve or gram -ve bacteria?
The bacteria present in curd are primarily Gram-positive bacteria. These include species like Lactobacillus acidophilus and Streptococcus thermophilus. Gram-negative bacteria are not typically found in curd as the fermentation process favors the growth of Gram-positive bacteria.
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.
Give the example for gram positivegram negative bacteria?
Typical gram-positive bacteria are staphylococci; typical gram-negative bacteria are bacilli.
Why gram negative bacteria more resistant to antibiotics?
Gram-negative bacteria have an outer membrane made of lipopolysaccharide and proteins, which the Gram-positive bacteria are lacking. More multi-drug resistance is being recognized in this class of bacteria than previously, and they are becoming a formidable foe in the environment because of the lack of new antibiotics to treat infections.
What kingdom is gram positive bacteria?
Kingdom Gram-Positive Bacteria is a kingdom within the domain Bacteria.
How is the Gram stain technique be of value in establishing purity of a culture of bacteria?
deffirent bacteria show different response to gram stainig procedure so bacteria are classified into two groups:a(gram positive bacteria)b(gram negitive bacteria)
Does Tetracycline kill gram positive or gram negative bacteria?
Tetracycline kills both gram positive and gram negative bacteria. The mode of action to which Tetracycline works to kill bacteria is that it inhibits protein synthesis which works against both gram positive and gram negative bacteria.
What types of bacteria do antibiotics kill?
Gram negative and gram positive bacteria.
Is lactobacillus bacteria gram positive bactaria?
Lactobacillus is gram positive bacteria
