Pseudomonas aeruginosa
A common pathogen causing various infections including pneumonia and skin infections
Salmonella and Shigella
Bacterial pathogens causing gastrointestinal infections
Gram Negative Bacilli
Bacteria with a distinct cell wall structure and causing various infections
Neisseria, Moraxella
Bacterial pathogens causing infections like acute otitis media, sinusitis, and bronchitis
Gram Positive Cocci
Bacteria with a thick cell wall causing skin, soft tissue, and respiratory infections
Bacteroides
Anaerobic bacteria causing gastrointestinal and aspiration pneumonia infections
Tetracyclines
A group of antibiotics effective against a wide range of bacteria
Fluoroquinolones
Antibiotics inhibiting the growth and reproduction of bacteria by interfering with DNA
replication
Aminoglycosides
Antibiotics that inhibit bacterial protein synthesis
,Carbapenems
Broad-spectrum antibiotics effective against a variety of bacteria
Polymyxins
Antibiotics that disrupt the structure of the bacterial cell membrane
Macrolides
Antibiotics that inhibit bacterial protein synthesis
Beta-lactamase inhibitors
Compounds that inactivate beta-lactamase enzymes, allowing beta-lactam antibiotics to
function effectively
Trimethoprim/Sulfamethoxazole
An antibiotic combination inhibiting bacterial folate synthesis
Penicillin
PCN G, PNC V
gram positive
Uses: syphilis, strep pharyngitis, dental infections, rheumatic fever
penicillinase resistance
(anti-staphylococcal PCN)
nafcillin, oxacillin, dicloxacillin
gram positive (staph)
uses: MSSA
Amino penicillins
Amoxicillin, ampicillin
gram positive, gram negative
, indications: acute otitis media, strep pharyngitis, listeria
beta lactase inhibitor PCN
amoxicillin clavulanate (augmentin)
ampicillin sulbactam
(unasyn)
Beta-lactamase inhibitors PCN
gram positive, gram Negative, anaerobes
indications: acute sinusitis, animal bites, aspiration pneumonia
Antipsuedomonal penicillins
Piperacillin- tazobactam
Ticarcillin- clavulanate
gram positive, gram negative (pseudomonas) anaerobes
PCN adverse effects
hypersensitivity reaction
hematologic reactions
GI(diarrhea)
Cephalosporins
as the cephalosporin generations go on from 1st to 2nd to 3rd and 4th they lose gram
positive coverage and gain gram negative
1st generation cephalosporins
