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.

RafaMycoplasma is a type of bacteria that lack a cell wall, making them resistant to antibiotics that target cell wall synthesis. Gram-positive bacteria, on the other hand, have a thick layer of peptidoglycan in their cell wall that retains the crystal violet stain in the Gram staining method. This key difference in cell wall composition affects how these bacteria are treated and classified in microbiology.

What cell structure is significantly different between gram-positive and gram-negative bacteria?
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 gram positive or gram negative?
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.
What is the gram stain of bacterial pneumonia?
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.
Is mycobacterium phlei gram positive or negative?
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.
Micrococcus luteus gram positive or gram negative?
Micrococcus luteus is a gram-positive bacterium.
