Gram-positive cocci are bacteria that have a spherical shape and stain purple with Gram stain due to their thick peptidoglycan cell wall. Streptococcus pyogenes is an example of gram-positive cocci that can cause infections such as pharyngitis, impetigo, cellulitis, necrotizing fasciitis, or rheumatic fever.
Gram-negative cocci are bacteria that have a spherical shape and stain pink with Gram stain due to their thin peptidoglycan cell wall and outer membrane. Neisseria gonorrhoeae and Neisseria meningitidis are examples of gram-negative cocci that can cause infections such as gonorrhea, meningitis, or septicemia.
Gram-positive bacilli are bacteria that have a rod-shaped shape and stain purple with Gram stain due to their thick peptidoglycan cell wall. Bacillus anthracis and Clostridium botulinum are examples of gram-positive bacilli that can cause infections such as anthrax, botulism, or tetanus.
Gram-negative bacilli are bacteria that have a rod-shaped shape and stain pink with Gram stain due to their thin peptidoglycan cell wall and outer membrane. Escherichia coli and Pseudomonas aeruginosa are examples of gram-negative bacilli that can cause infections such as urinary tract infection, wound infection, or sepsis.
