Although mycoplasma lack a cell wall and therefore test gram negative, they are considered to be descendents of 'nonsporulating and endospore forming gram-positive bacteria' (Madigan et al., 2009), such as Lactobacilli, Bacilli and Streptococci, (Dandekar et al., 2002), which have lost their cell wall. Mycoplasmas are therfore classed as gram- positive bacteria. This is supported by ribosomal RNA and DNA analysis.
What else can I help you with?
Does Mycobacterium phlei grow on EMB agar?
Mycobacterium phlei is a non-fastidious organism that is commonly found in soil and water. It is not commonly grown on Eosin Methylene Blue (EMB) agar, as EMB agar is more selective for gram-negative enteric bacteria. Instead, Mycobacterium phlei is typically cultured on media specifically designed for mycobacteria, such as Middlebrook agar or Lowenstein-Jensen agar.
Is TB a gram negative bacteria?
No, TB (Mycobacterium tuberculosis) is a gram-positive bacteria.
What 2 genera of bacteria are gram variable?
Two genera of bacteria that are gram variable are Mycobacterium and Corynebacterium. Gram variable bacteria may appear to be both gram-positive and gram-negative due to differences in their cell walls.
What colors gram positive and gram negative bacteria?
Gram-positive cells are purple and the Gram-negative cells are red.
Is bacillius subtilis gram positive or gram negative?
Gram positive

Is mycolic acid found in gram positive and gram negative cell wall composition?
Mycolic acid is primarily found in the cell walls of mycobacteria, which are a type of bacteria that include the causative agents of tuberculosis and leprosy. It is not typically found in the cell walls of other bacteria, including those classified as gram-positive or gram-negative.

Is cholera gram negative or gram positive?
gram negative
Is MRSA gram positive or gram negative?
gram positive
Is Providencia stuartii gram positive or gram negative?
its gram negative
What colors gram positive and gram negative bacteria?
Gram-positive cells are purple and the Gram-negative cells are red.
Is staphylococci epidermidis gram-negative or gram-positive?
gram positive
Is bacillius subtilis gram positive or gram negative?
Gram positive
Is gram positive bigger than gram negative?
Gram-positive bacteria and Gram-negative bacteria are different in their colouration when dyed and viewed with a light microscope. Gram-positive appear violet, and Gram-negative appear red. Gram-positive and Gram-negative classification, however, has nothing to do with size.
Mycobacterium (Aerobic Chemoorganotrophs)?
Gram-positive bacterium, live on dead and decaying matter
