Gram positive organisms are divided into 3; GP cocci, GP clusters, GP rods (rarely in humans)
list GP cocci, GP Cocci (s. pneumoniae, GAS, enteroccous, S. pyogenes).
list GP cluster Cluster (coagulse + S. Aureus inclusding MRSA) Cluster (Coagulase - s. epidermidis)
Gram negative organisms are divided into: GN Cocci, GN Rods
GN rods divided into Enterobacterciae (PECKS), Non-lower gut (H. influenzae and H. Pylori), Non-fermenting (PASS)
Where do Anaerobes reside primarily in gut, necrotic tissue (limited oxygen), abscess
Classify Anaerobes Bacteroids (B. Fragilis), Clostrida (C. diff, C. perfinges)
Classify Atypical MLS (mycoplasma, legionella,chlamydia)
GAS/S. Pyogenes infection SSTI, URI
S. Aureus SSTI, POEB, also MRSA
S. Pneumoniae CAP, Meningitis, sinusitis, bacteremias
Enterococcus UTI, IA, Endocarditis (audient)
Enterobacteriacea (PECKS) infection (HABIT) live in gut HABIT (UTI, Intraabdominal infection, bacteremias, HCAP)
Non Enterobacteriacea (non-lower gut) H. Influenzae URI/CAP
Non Enterobacteriacea Non-fermenting: HCAP, HCAI, Diabetic foot infections,
S. epidermidis (gram positive ) coagulase -, Cocci, skin
Cocci (chains) GAS, S. Pneumoniae (also pairs), S. Pyogenes
Bacilli, lactose fermenter, gram positive enteroccous
cluster (coagulase + and -) S. epidermidis, S. Aureus
GN Cocci divided into GMC (N. G/ N. M/ M. C)
Non-fermenting (PASS) infection Opportunistic infection in critically ill or immunosupressed patients.
Anaerobes (clostridium d/p) reside oral anaerobes, IA's, colitis, aspiration pneumoniae
MLS character atypical act like virus. difficult to culture and treat. legionella is most serious
Penicillin GAS/S. pyogenes, treponema (use on S. pneumoniae if it is susceptible)
Amoxicilliln, Ampicillin S. pneumoniae, enteroccus if susceptible. good coverage with gm - if they don't produce beta lactamase
Nafcillin (IV), Dicloxacillin (PO) MSSA, GAS/S. pyogenes
Ticarcillin (Clavulanate) and Piperacillin (Tazobactam)- zosyn augmentin ampicillin (sunbactam): unasyn MSSA, anaerobes, gram - coverage including pseudomonas
Pearl from CDC vaccinaatteeeee, wash hand, remove unnecessary catheter, know ur antibiograms
