General Information about gram-negative bacteria. Gram-negative bacteria cause infections including pneumonia, bloodstream infections, wound or surgical site infections, and meningitis in healthcare settings. Gram-negative bacteria are resistant to multiple drugs and are increasingly resistant to most available antibiotics.
Cocci bacteria are spherical in shape and include Gram-positive bacteria Staphylococcus aureus, Streptococcus pyogenes and Streptococcus pneumoniae while Gram-negative cocci bacteria include Neisseria gonorrhoeae and N. meningitidis. The gram-positive cocci are the leading pathogens of humans. It is estimated that they produce at least a third of all the bacterial infections of humans, including strep throat, pneumonia, otitis media, meningitis, food poisoning, various skin diseases and severe types of septic shock. The Gram-negative cocci, notably the neisseriae, cause gonorrhea and meningococcal meningitis. Staphylococcus aureus is most commonly found in the nasal membranes, skin and GI tract of humans. It is the most likely to cause disease and is considered a pathogen.
