Flashcards in Gram negative coccobacillus Deck (38):
1

Haemophilus Influenzae Type B causes

Epiglottitis, Otitis Media, and Meningitis

2

Haemophilus Influenzae Type B growth

X and V on Chocolate

3

Haemophilus Influenzae Type B virulence

IgA protease and capsule

4

Haemophilus Influenzae Type B Dx

X and V on Chocolate

5

Haemophilus Influenzae Type B Tx

Cefriaxone (3rd gen cephalosporin) and Rifampin for close contacts (DNA dependent RNA poly blocker)

6

Haemophilus Influenzae Type B prevention

HiB vaccine with polysacc capsule on diphtheria toxoid

7

Legionella pneumophila causes...

Legionairres (atypical pneumonia with micro abscesses) and Pontiac fever (2-5 days) since legionairres drive pontiacs

8

Legionella pneumophila growth

Charcoal with iron and cysteine and silver stain

9

How you get Legionella pneumophila

Water sources like AC systems

10

Legionella pneumophila diagnosis

Stain, growth, or urinary antigen

11

Legionella pneumophila Tx

Macrolide erythromycin which binds 50S and prevents tRNA bound at the A site from moving

12

Legionella pneumophila virulence

Pilin binds epithelium --> alv macs --> prevent PL formation --> live in macrophages

13

Bordatella pertussis causes

Whooping cough (catarrhalis, paroxysmal, and recovery)

14

Bordatella pertussis growth

Bordet Gengou DAMN IT

15

Bordatella pertussis virulence

Filamentous hemgluttinin (whooping with filaments) bind epithelium --> AB toxin ADP ribosylates --> tracheal cytotoxin

16

Bordatella pertussis Dx

Bordet Gengou

17

Bordatella pertussis Tx

Macrolide erythromycin (binds 50 s and prevent trNA from leaving A site)

18

Bordatella pertussis prevention

DTAP at 2, 4, 6, 18, before school and every 10 years

19

Brucella species cause

Undulating fever

20

Brucella species transmission

Unpasteurized cheese made by brutes

21

Brucella species Dx

Skin test or serology

22

Brucella species histology

Granulomas

23

Brucella species Tx

Tetracycline doxycycline and aminoglycoside gentamicin

24

Brucella species complication

Osteomyelitis

25

Francisella tularensis causes...

Tularemia (ulceronodular, oculonodular, pulmonary, typhoidal)

26

Francisella tularensis transmission

Francisella tularensis Tx

Aminoglycoside Streptomycin

30

Pasteurella multocida causes

Cellulitis and osteomyelitis

31

Pasteurella multocida transmission

Cats and dogs bite you

32

Pasteurella multocida Dx

Oxidase and catalase + and bipolar staining

33

Pasteurella multocida Tx

Do not close wound, given beta lactam penicillin G so it can block transpeptidation and PG synthesis

34

Bartonella henselae causes...

Cat scratch fever (Bacillary angiomatosis), with ocular infection (Parinaud's vertical gaze palsy), HSM (peliosis hepatis), encephalitis, and ostemyelitis

35
