1 Gram-negative cocciâ Neisseria meningitidis causes meningitis while Neisseria gonorrhoeae causes the sexually transmitted disease gonorrhea. 2  Gram-positive bacilliâ Bacillus anthracis (anthrax) can cause skin infections or pneumonia (also a bioterrorism agent); Listeria monocytogenes can cause foodborne illnesses.
Specific to gram-positive bacteria is the presence of teichoic acids in the cell wall. Some of these are lipoteichoic acids, which have a lipid component in the cell membrane that can assist in anchoring the peptidoglycan.iolet stained gram-positive cocci and pink stained gram-negative rod-shaped bacteria. Gram-positive bacteria are bacteria that give a positive result in the Gram stain test. Gram-positive bacteria take up the crystal violet stain used in the test, and then appear to be purple-coloured when seen through a microscope.
