what is used to treat staph eidermis
gent + vancomycin
what is used to treat campylobacter
ciprofloxacin/ erythromycin
what is used for C. diff
metronidazole, and then if still present vancomycin
what are the 4 that cause C diff
Cephalosporins, Clindamycin, Ciprofloxacin,
Co-amoxiclav
what are beta lactams
cell wall inhibitors- penicillins, cephalosporins (except vancomycin)
are cocci gram neg or pos
all gram pos except neisseria spp
are bacilli gram neg or pos
all gram neg except dipethia and some more
what treats intracellular bacteria
tetracyclines and macrolides
what antibiotics should be avoided in pregnant women
tetracyclines, aminoglycides, fluoroquinolones
how do macrolides work
inhibits protein synthesis (bacteriostatic)
how do quinolones work
inhibit nucleic acid synthesis
how does gentamicin work
inhibits protein synthesis
how is a mild/mod CAP treated
amoxicillin (or doxycyclin)
how is a severe (3-5) CAP treated
co- amoxiclav IV + doxycycline (or levofloxacin)
how is a severe HAP treated
IV amoxicillin + metronidazole + gentamicin (if allergic replace amox with co-trimoxazole)
how is a non severe HAP treated
PO amoxicillin + metronidazole (if allergic co-trimoxazole)
how is an acute exacerbation of COPD treated
(only if purulent sputum)
amoxicillin, 2nd line doxycycline
how is an acute cough/ bronchitis treated
amoxicillin, 2nd line doxycycline
how is native valve indolent (subacute) endocarditis treated
amoxicillin + gentamicin
how is native valve severe sepsis (acute) endocarditis treated
flucloxacillin
how is prosthetic valve or suspected MRSA treated
vancomycin + rifampicin + gentamicin
how is native valve severe sepsis treated + risk of resistant pathogens
vancomycin + meropenem
how is a non severe C diff infection treated
metronidazole po
how is a severe c diff infection treated
vancomycin (PO/NG) +/- IV metronidazole
how are is peritonitis/ biliary tract. intra-abdominal infections treated

none
how is a mild provem spontaneous bacterial peritonitis treated
co-trimoxazole PO
how is a severe proven spontaneous bacterial peritonitis treated
peperacillin/ tazobactam
how is an infection of unknown cause treated
IV amoxicillin + metronidazole + gentamicin (+ flucloxacillin/ vancomycin if staohylcocci concern)
if allergic
(IV vancomycin instead of amoxicillin)
