Acid fast organisms - Nocardia, Mycobacterium
Chocolate agar with factor V (NAD+) and X (hematin)
H. influenzae
Components [3] of Thayer-Martin/VPN media
Vancomycin - inhibits gram +; Polymyxin - inhibit gram - except Neisseria; Nystatin - inhibits fungi
Thayer-martin agar [2]
N. gonorrhoeae; N meningitidis
Bordet-Gengou )potato) agar
B. pertussis
Tellurite plate; Loffler’s media

Catalase + Organisms [7]
You need PLACESS for you CATs.
Pseudomonas; Listeria; Aspergillus; Candida; E.coli; S. aureus; Serratia
Urease-positive bugs
“CHuck Norris hates PUNKSS”;
Cryptococcus; H. pylori; Proteus; Ureaplasma; Nocardia; Klebsiella; S. epidermidis; S. saprophyticus
S. aureus virulence factor. Binds Fc region of Ig. Prevents opsonization and phagocytosis.
Protein A
Virulence factor secreted by S. pneumonia; H. influenza type B; and Neisseria
IgA protease
Group A strep virulence factor that prevents phagocytosis
M protein
Labs; staph vs strep
Catalase: (Staph catalase +)
Labs: Differentiate types of Staph
Coagulase: S. aureus = Coagulase +;
Novobiocin sensitive: S. epidermidis; Novobiocin resistant: S. saprophyticus
