there is a slight, but important difference, between these two forms of bacteria.
Mycoplasma are cell wall deficient bacteria that have ALWAYS been cell wall deficient.
bacteria are more insidious than Mycoplasma because they are able to shape shift between a normal bacterial state, with a cell wall, and a cell wall deficient form. Organisms such as Borrelia Bergdorferi, are l-form because they actually exist in multiple different forms, including a cell wall deficient form. same with chlamydia pneumonia.
Mycoplasma bacteria never have a cell wall, therefore they are not technically classified as l-form.
The difference between a gram positive and gram negative bacteria is the thickness/presence of the peptidoglycan layer secreted on the outside of the plasma membrane
Candida albicans is a yeast and belongs to the fungal kingdom, so it does not have a gram classification like bacteria. Gram staining is a technique used to differentiate between gram-positive and gram-negative bacteria based on the composition of their cell walls.
Bacterial pneumonia is typically caused by organisms such as Streptococcus pneumoniae, Haemophilus influenzae, and Mycoplasma pneumoniae. These bacteria can have different Gram stain characteristics: S. pneumoniae is Gram-positive, H. influenzae is Gram-negative, and M. pneumoniae lacks a cell wall and is therefore classified as "neither" in Gram staining.
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.
Gram Positive.
They have different cell walls.

Gram positive bacteria appear purple or blue when stained with the Gram stain, while gram negative bacteria appear pink or red. This color difference is due to the thickness of the cell wall and the presence of an outer membrane in gram negative bacteria.
The peptidoglycan layer of the cell wall is thicker for a Gram-positive bacterium.

B. anthracis, C. tetani, C. perfringens, C. botulinum, C. Diphtheriae, Gardnerella, Lactobacillus, Lactobacillus, M. leprae, M. tuberculosis, Mycoplasma and many more are Gram +.

what are the similarities of the negative gram and positive gram? both will only relate to the bacterias but not any other microorganism.
Bacterial pneumonia is typically caused by organisms such as Streptococcus pneumoniae, Haemophilus influenzae, and Mycoplasma pneumoniae. These bacteria can have different Gram stain characteristics: S. pneumoniae is Gram-positive, H. influenzae is Gram-negative, and M. pneumoniae lacks a cell wall and is therefore classified as "neither" in Gram staining.
Mycoplasma is an example of an organism that does not stain on a Gram stain due to its lack of a cell wall. Mycoplasma is classified as a bacterium, but its unique cell wall composition causes it to not retain the crystal violet stain in the Gram staining process.
gram- negative and gram- positive bacteria differ in their response to different antibiotics
