2

Specific ___ put you at risk of different opportunistic infections.

immunodeficiencies

3

What is a prodrome?

Classical symptoms BEFORE main symptoms of infection set in

e.g tingling before vesicles appear in herpes zoster

4

What are some molecular tests which can be used to detect bacteria in infection?

MALDI-TOF

Chromogenic media (agar which turns different colours for different bugs)

PCR

Whole genome sequencing

5

Bacteria are Gram ___ or ___ .

Which shapes?

Gram +ve / -ve

Cocci, bacilli or a mixture

6

What are the growth types of bacteria?

Aerobic (Pseudomonas is a strict aerobe)

Anaerobic (targeted by metronidazole)

7

relearn coagulase tests for staph

and haemolysis for strep

8

syphilis is a spirochaete

9

vibrio shape - think cholera

10

haemolysis

alpha - strep viridans (greek for green), pneumoniae - GREEN

gamma/non - enterococci - no change

beta -  GAS (e.g strep pyogenes) - WHITE

11

streptococci - penicillin

gamma haemolytic strep are a bit more complicated

12

gram negative bacilli tend to be anaerobic - klebsiella, e coli, enterobacter

pseudomonas is a strict aerobe

13

"strict lactose fermenter" usually means e coli

14

gram negative cocci - neiserria meningitidis and gonorrhoeae

15

penicillin / clarithromycin / vancomycin - gram positives

gentamicin / aztreonam - gram negatives

metronidazole - anaerobes
