Gram-Positive Describing the group of bacteria that have a single cell wall that is structurally
less complex and contains more peptidoglycan (dye stays here) than the cell wall of gram-
negative bacteria. Gram-positive bacteria are usually less toxic than gram-negative bacteria.
Gram-Negative Describing the group of bacteria that have a double cell wall and contains
less peptidoglycan than the cell wall of gram-positive bacteria. Gram-negative bacteria are
often more toxic than gram-positive bacteria.
Harder to kill d/t double cell wall
Anaerobic bacteria bacteria that do not require oxygen to survive; thrives in the gut
Diplococci cocci growing in pairs
Streptococci bacteria that form a chain
staphlococci berry shaped bacteria in clusters
Bacilli Rod shaped bacteria
, spirochete spiral shaped bacteria
B. burgdorferi (lyme disease)
Flagella A long, whip-like filament that helps in cell motility. Many bacteria are flagellated,
and sperm are flagellated.
Neisseria gonorrhoeae membranes studded with projecting pili that allow adherence to the
genital mucosa and movement along the epithelial cells to spread genital infections
S. Pyogenes Group A strep (strep throat)
M proteins: bind fibrinogen and block compliment attachment
Exotoxin like streptolysin that lyses RBCs
ALWAYS susceptible to Penicillins
Use Antigen test- specific
S. Aureus gram positive cocci
Anaerobic (can't live in gut d/t decreased pH)
Contains genome that neutralize human neutrophils
Some produce leukocidin that break down platelets and neutrophils
MRSA produces a PBP, PBP2a that inhibits intracellular entrace that inactivates penicillins
Penicillin Binding Proteins proteins in bacteria that serve as target sites for penicillin to bind
