26
Pen G activity
gram pos: cocci, meningococci, bacilli, anaerobes spirochetes (DOC chlam, lymes) little gram neg activity
27
Pen V activity more stable than ? Tx ? infx, streptococci, ? pneumococci
Pen G | oropharyngeal, pcn-SENSITIVE
28
extended spectrum PCNs
pen G & gram neg (HEMP) H flu, E coli, Morax, Proteus
29
Ticercillin & piperacillin- only pcn? | otherwise same as amos
active against pseudomonas, klebsiella, bacteroides
30
MRSA develops from resistance via? | so does ? and ?
modification of PBPs | pen-resistant pneumococci, enterococci
31

penicillinase producing organisms
32
food decreases absorption in all PCN except?
amox
33
Weil's Dz (?) and Actinomycosis are tx by?
(leptospira) Pen G
34
? also treat salmonella, shigella, campylobacter
ampicillin (gastroenteritis)
35

H pylori, GI tract infxn Listeria meningitis (G+ meningitis!), Gastroenteritis
36
make beta lactamase (2)
staphylococcus | enterobacter
37
make penicillinase (6) steph klub makes HEMP! (formerly
