-Staphylococcus aureus
-Corynebacterium
-Streptococcal
-Propionibacterium
-Pseudomonas aeruginosa
-Candida Albicans
What is the most common and broadest categories of bacteria? - CORRECT ANSWER✅✅-gram positive
-gram negative (majority of the bacteria)
-Aerobic (require oxygen)
-Anaerobic (don't require oxygen)
*facultative (can live w and w/o O2)
*obligate (lives only with O2)
Gram-positive cocci, aerobic, cluster, coagulase + - CORRECT ANSWER✅✅-staph aureus
-causes nosocomial/community acquired infections
-treat with Penicillins (nafcillin, oxacillin, dicloxacillin
-treat with cefazolin (Ancef, 1st gen cephlasporin)
Gram-positive cocci, aerobic, cluster, coagulase - - CORRECT ANSWER✅✅-staph
epidermidis*(prosthetic joints, mech valves, intravascular catheters)
-staph hominus
-staph hemmolyticus
-staph saprophyticus*(2nd most common cause of UTI)
-staph warneri
, Gram-positive cocci, aerobic, pairs, alpha hemolytic - CORRECT ANSWER✅✅-strep pneumoniae
-most common cause of CAP, bacterial meningitis, sepsis, otitis media, sinusitis
-Asplenia should get staph vaccination
Gram-positive cocci, aerobic, chains, alpha hemolytic - CORRECT ANSWER✅✅-strep viridans
-three subtypes:
1) strep mutant-dental caries
2) strep sanguis-subacute bacterial endocarditis
3) strep intermedius-abscesses
Gram-positive cocci, aerobic, chains, beta- hemolytic - CORRECT ANSWER✅✅-strep pyrogens group A
*(produces pus, transmitted by resp droplets, causes pharyngitis, impetigo, erysipelas, cellulitis,
*necrotizing fascitis, rheumatic fever, post-streptococcal glomerulonephritis)
-strep agalactiae group B
-strep bovis group D (usually associated with colon cancer, needs GI workup)
Gram-positive cocci, obligate anaerobes, pairs&chains - CORRECT ANSWER✅✅-Petococcus
-peptostreptococcus
Gram-positive cocci facultative, anaerobes, pairs&chains - CORRECT ANSWER✅✅-Enterococcus
(requires extended course of BS antibiotics)
-two subtypes: (both cause nosocomial infections, UTIs in catheter patients, post-surgical peritonitis,
subacute bacterial endocarditis)
1) enterococcus faecalis
2) enterococcus faecium
When should you NOT delay antibiotics (before cultures)? - CORRECT ANSWER✅✅-with fever and
neutropenia because it is fatal
