1

Histo vs coccidio

  • Histo = circles in macrophages Coccidio = endospores in spherules

2

slap cheeck =

5th disease; parvo B19, erythema infectiosum

3

Altered pol genes in HIV via

antiretroviral chemotherapy - protease inhibitors and RT inhibitors

4

Altered env genes in HIV via

escape from host neutralizing Abs

5

Antipseudomonals - 6 groups and specific names

  • Penicillins: pipercillin, ticarcillin, cefepime (4), ceftazodime (3)
  • Carbapenems: imipenem (w/ cilistatin), meropenem
  • Aminoglycosides: gentamycin, amikacin, tobramycin
  • ciprofloxacin
  • aztreonam
  • FOR MDR: colistin, polymixin B

6

H. flu vs Nisseria agar

H. flu = chocolate = NAD (V) and hematin (X)

 

Nisseria = thayer martin = Vp T Cn Nf = vanco (+), trimethoprim, colistin (-), Nystatin (f)

7

PRP

type b h. flu capsular polysaccharide

8

Intracellulars:

- bacteria obligates:

- bacteria facultative:

- fungi:

- Protozoa:

- BO: coxiellia, chlamydia, rickettsia

- BF = salmonella, nisseria, brucella, mycobacterium, listeria, fransicella, legionella, yersinia

- crypto, histo, PCP

- toxo, plasmodium

9

Difference between EHEC and other E. colis

EHED does NOT ferment sorbitol on MacConkeys and it does NOT produce glucoronidase

10

Role of M protein

S. pyogenes major virulence factor.  Prevents phagocytosis and complement activation.

 

Abs to M protein made by host also cause RHD and PSGN

11

Virulence factor of E. coli responsible for neonatal meningitis

K1 capsular antigen (FA 138)

12

Virus tht takes its envelope from the nuclear membrane instead of the PM

Herpesviruses

13

Food item for EHEC

raw beef

14

5 bacterial toxins coded in phages

Shiga toxin - EHEC

Botulinum toxin

Cholera toxin

Diptheria toxin

Erythrogenic toxin - S. pyogenes (scarlet fever)
