Flashcards in Classification of pathogenic bacteria - Gram negative Deck (23):
1

Cocci

- Neisseria spp.
- Moraxella catarrhalis

2

Neisseria meningitidis

Inflame meninges and septicaemia

3

Neisseria gonorrhoea

Urethritis and inflammatory pelvic disease

4

Moraxella catarrhalis

Respiratory tract infection prevalent in those with underlying lung pathology

5

Coliforms

Organisms in enterobacterioceae family in gut
Use lactose fermentation test

6

Ecoli

Lactose fermenter
Cause UTI
Very virulent

7

Enterotoxogenic E.coli

Travellers diarrhoea

8

Enterohaemorrhage E.coli

Bloody diarrhoea

9

Salmonella spp.

Non lactose fermenter and over 1500 serotypes

10

Salmonella enterica

Self limiting enterocolitis with or without bloody diarrhoea

11

Salmonella typhi

Cause typhoid fever

12

Shigella

Lactose fermenter and cause of diarrhoea

13

Klebsiella spp

Cause of UTI and pneumonia

14

Proteus spp

Cause UTI

15

Curved bacilli

Camplylobacter found in chicken flocks which causes bloody diarrhoea

16

Spiral bacilli

Helicobacter pylori - human stomach, cause ulcers

17

Haemophilius influenza

Cocco bacilli and cause respiratory tract infections and the capulate form causes meningitis

18

Pseudomonas spp

Non lactose fermenter found in drains and sinks and can cause acquired sepsis
Sensitive to limited range of antibiotics

19

3 Anaerobes

Bacteriodes fragilis, prevotella and porphyromonas

20

Bacteria which cannot be gram stained or cultured

Mycobacteria, chlamydia and spirochaetes

21

Mycobacterium

Use ZN stain as resistant to acid/alkali decolourisation
Cause TB and can cause leprosy

22

Spirochaetes

Syphilis
Lymes disease
Leptosporosis - liver and renal failure
Use dark ground microscopy, immunofluorescence or serology

23

Chlamydia

Detect by culturing in cells or NAAT on urine or swabs
Respiratory infection
