What bacteria has a resistance to penicillin by changing it OM porins?
P. aeruginosa
Which bacteria have a resistance to penicillins by changing PBP's
Pneumococci for penicillin G
This anitbiotic inhibits transpeptidation by preventing cross-linking of peptidoglycan chain.
Penicillin is bactericidal or bacteristatic
Name the inhibitors of cell wall synthesis
penicillin, cephalosporins, carbapenems, monoboctams (B-lactams) vancomycin, bacitracin, & fosfomcyin (polypeptides)
which antibiotics create hypersensitivity?
ampicillin and cephalosporins
What class of antibiotic is B-lactam resistant?
Class II (very narrow spectrum)
MRSA and MRSE are treated with?
Anti-staph antibiotics?
very narrow spectrum (class II) methicillin, nafcillin oxacillin, cloxacillin, and dicloxacillin.
Drug of choice for gram + and - cocci?
narrow spectrum (class I)
Extended spectrum drugs are used w/ penicillinase inhibitors. What are they?
amoxicilln + clavulanic acid (Augmentin): PO
ampicillin + sulbactam: IV
ticarcillin + clavalanic acid (Timentin):IV
Peperacillin + tazobactam:IV
Why do we use aminoglycosides in combination with penicillins and cephalosporins?
1) inhibition of cell wall syn thus enhanced antimicrobial activity of aminoglycosides.
Antibiotic used to treat oropharingeal infections.
Penicillin V
Standard penicillins not active against .....
negative bacilli
Active against spirochetes and + bacilli.
narrow spectrum penicillins
Drug combo for enterococcal endocarditis. (necessary)
Peni G and aminoglycoside
Drug combo for meningitis caused by P. aeruginosa.
Cephalosporins and aminoglycosides.
Drug combo for pseudomonal infections.
Antipseudomonal penicillin and aminoglycoside.
MOA's of penicillins
1) inactivation of transpeptidases
2) peni binding proteins
3) prevent cross-linking of peptidogylcans
Bacteria that form penicillinases
H. influenza
Three drugs used for UTI's
-aminopenicillins (extended spectrum)
Used for UTI's, sinusitis, otitis, and lower respiratory infections.
Aminopenicillins (extended spectrum)
Drug of choice for L. monocytogenes
Absorption characteristic of penicillin.
poor absorption via oral except for amoxicillin and peni V
oral forms of penicillin
peni V and amoxicillin
depot forms of penicillins
procraine peni G and benzathine peni G
Distribution of penicillin
poor CNS penetration
cross placenta- not teratogenic
This chemical prevents excretion of penicillin.
What is the drug of choice used as a prophylactic of orhtopedic, abdominal, and pelvic surgeries.
1st generation cephalosporins
what are the dna repair and genomic insability disorder in cancer?
BCLA 1 and 2 and HNPCC for dna repair and blooms syndrome, ataxia-telangiectasia, fanconi anemia, and xermoderma pigmentosa.
What is the drug of choice for Enterococus faecalis.
(most broad-spectrum drug)
What is the most broad spectrum antibiotic
Chloramphenicol is broad spectrum with what other antibiotic?
contraindicated in pregnancy, breast feeding women and children under 8.
tetracycline (deposits in primary teeth and growing bones of children)
Antibiotic with phototoxicity
Antibiotic that produces local tissue toxicity.
Bacteria confer resistance by pumping out the drug and preventing intracellular accumulation to this antibiotic.
Toxicity of this antibiotic is phlebitis, "Red man syndrome", chills, and fever.
This antibiotic produces phototoxicity as a side effect.
These two antibiotics may cause pseudomembranous colitis.
clindamycin and penicillin
This antibiotic may cause irreversible ototoxicity.
Aminoglycosides are administered parenterally except for two. Which are they?
Neomycin and Kanamycin (topical)
These antibiotics are special in that they have a postantibiotic effect.
Where are aminoglycosides found in high concentrations?
renal cortex
endolymph and perilymph of inner ear.
This combo of drugs is used as first-line therapy for acute toxoplasmosis.
sulfadiazine (antibiotic) and pyrimethamine (antiparasite)
This antibiotic is used to treat bacterial conjuntivitis.
sodium sulfacetamide
Azithromycin and clarithromycin are what type of antibiotic?
Macrolides (moderate spectrum)
Used to prevent sepsis in burn patient and pt's with wounds.
mafenide acetate but silver sulfadiazine is less toxic and preffered
True or false. The preferred method of administration of erythrmycin is parenteral.
false - oral as enteric coated.
Used to treat UTI's of E.coli and P. mirabilis
Who Takes Care of Pseudomonas?
Ticarcillin Carbenicillin, and Piperacillin.
