1

What is the human microbiome

The term used to describe all microorganisms within the human body

2

What are commensal bacteria

Bacteria found colonising in a normal healthy body

3

What are the first bodily systems to be colonised by bacteria

The urinary tract, Gi tract and then other muscousal surfaces

4

What is the role of commensal bacteria

Protecting against and outcompeting pathogenic bacteria
Aiding digestion and vitamin production
Stimulating an immune response

5

What can occur upon the distribution of normal flora to other body parts

This can lead to infections as normally non-pathogenic organisms may become opportunistic

6

What is a pathogenic organism

One that can or has the potential to cause disease

7

What are opportunistic conditions

When a pathogen in normal flora has taken advantage of an opportunistic situation to cause a disease

8

What are the main points of entry for a pathogen

Urogenital tract
Respiratory tract
Conjunctiva
Scratch, injury

9

What are the virulence factors of a bacteria pathogen

The factors that make the bacteria pathogenic

10

What are the key virulence factors (6)

Entry into the host
Ability to adhere onto cells
Ability to invade host tissues
Toxin production
Avoiding the immune system
The potential for antibiotic resistance

11

What is the role of a viral capsid

It protects the genome and provides more resistance to drying

12

What are the two type of virus cells

Enveloped and naked virions

13

What is the envelope of a virion cell derived from and what is on the surface

The cell it has invaded
Often contain virally derived glycoproteins that allow it to bind and be taken up by cells

14

How many types of viral genomes are there

7

15

What causes disruption of normal flora

Immunocompromised state
Ageing
Prolonged hospitalisation
Antibiotic treatment

16

What is the transient colonisation of bacteria

This is the spreading of bacteria from one person to another through contact or airbone
Disappear over time and don't intefere

17

What is premanent colonisation of bacteria

Contact with a person that find permanent colonisation on a person

18

What is the staining technique of bacteria

Gram staining

19

What colour are gram negative and positive bacteria

Pink is gram-negative
Purple is gram positive

20

What type of bacteria are the gonnorhea and meningitis pathogen

Gram negative coccus

21

What are examples of some gram positive cocci

The pathogens for food poisoning, wound infection and pneumonia

22

What is an example of a coccobacillus

haemophilius influenzae which causes meningitis and pneumonia

23

What are some example of gram negative rod bacteria

E.coli
Salmonella
Many opportunistic infections

24

What are endospores

These are formed by certain bacteria and are dormant forms of a cell that can survive high temperature, Uv radiation, desiccation, chemical damage and enzymatic destruction

25

What is an example of vibrio bacteria

Vibrio cholerae

26

What is an example of a spirochete bacteria

Treponema pallidum that causes syphilis

27

What is an example of a gram -ve spiral

Campylobacter jejuni which causes gastroenteritis

28

What is interprofessional education

This is when students from various professions learn from each other to improve their quality of care

29

What are histopathologists

They specialise in making diagnoses of different types of lung cancer from biopsy results

30

What is the role of specialist nurses

These liase with the patient to give support and advice to them and their family
