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
Look at them under a microscope! If they are cocci, they will look like balls. If they are rods, they will look like...rods!
Mycoplasma (Gram +), Hemophilus (Gram -), Klebsiella (Gram -), Legionella (Gram -) among many that cause pneumonia. Do have another in mind?

Gram positive !!
They have different cell walls.

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.
Gram positive !!
gram- negative and gram- positive bacteria differ in their response to different antibiotics
