alcoholics at much higher risk of strep pneumoniae, neisseria meningitidis
Specific ___ put you at risk of different opportunistic infections.
What is a prodrome?
Classical symptoms BEFORE main symptoms of infection set in
e.g tingling before vesicles appear in herpes zoster
What are some molecular tests which can be used to detect bacteria in infection?
Chromogenic media (agar which turns different colours for different bugs)
Whole genome sequencing
Bacteria are Gram ___ or ___ .
Gram +ve / -ve
Cocci, bacilli or a mixture
What are the growth types of bacteria?
Aerobic (Pseudomonas is a strict aerobe)
Anaerobic (targeted by metronidazole)
relearn coagulase tests for staph
and haemolysis for strep
syphilis is a spirochaete
vibrio shape - think cholera
alpha - strep viridans (greek for green), pneumoniae - GREEN
gamma/non - enterococci - no change
beta - GAS (e.g strep pyogenes) - WHITE
streptococci - penicillin
gamma haemolytic strep are a bit more complicated
gram negative bacilli tend to be anaerobic - klebsiella, e coli, enterobacter
pseudomonas is a strict aerobe
“strict lactose fermenter” usually means e coli
gram negative cocci - neiserria meningitidis and gonorrhoeae
penicillin / clarithromycin / vancomycin - gram positives
gentamicin / aztreonam - gram negatives
metronidazole - anaerobes
