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.
What else can I help you with?
Is klebsiella gram positive or negative?
i believe it is a gram bacteria which causes respiratory illness.
What is the structural difference in the cell walls of gram-negative bacteria that distinguishes them from gram-positive bacteria?
Gram-negative bacteria have a thinner peptidoglycan layer in their cell walls compared to gram-positive bacteria. Additionally, gram-negative bacteria have an outer membrane that contains lipopolysaccharides, which is absent in gram-positive bacteria.
Does Gram-positive bacteria have lipopolysaccharides?
No, Gram-positive bacteria do not have lipopolysaccharides.
Do gram positive bacteria have an outer membrane?
No, gram positive bacteria do not have an outer membrane.
Do gram positive bacteria have lipopolysaccharides (LPS)?
No, gram positive bacteria do not have lipopolysaccharides (LPS).
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
What kingdom is gram positive bacteria?
Kingdom Gram-Positive Bacteria is a kingdom within the domain Bacteria.
Is azospirillum a gram positive bacteria?
Gram positive
Is klebsiella gram positive or negative?
i believe it is a gram bacteria which causes respiratory illness.
What is the structural difference in the cell walls of gram-negative bacteria that distinguishes them from gram-positive bacteria?
Gram-negative bacteria have a thinner peptidoglycan layer in their cell walls compared to gram-positive bacteria. Additionally, gram-negative bacteria have an outer membrane that contains lipopolysaccharides, which is absent in gram-positive bacteria.
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.
Does Gram-positive bacteria have lipopolysaccharides?
No, Gram-positive bacteria do not have lipopolysaccharides.
Give the example for gram positivegram negative bacteria?
Typical gram-positive bacteria are staphylococci; typical gram-negative bacteria are bacilli.
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.
Is lactobacillus bacteria gram positive bactaria?
Lactobacillus is gram positive bacteria
What types of bacteria do antibiotics kill?
Gram negative and gram positive bacteria.
