What is an infection?
- The invasion and multiplication of microorganisms (pathogens) that are not
normally present within the body.
- An infection may cause no symptoms or it may cause symptoms and be clinically
apparent.
- An infection may remain localised, or it may spread through the blood or lymphatic
vessels to become systemic (body-wide). (E.g. sepsis)
What is commensal bacteria?
- micro-organisms which are present on body surfaces covered by epithelial cells
and are exposed to the external environment (GI and respiratory tract, vagina, skin,
etc.).
- 'Good' bacteria help protect against pathogens
What are the surface membrane barriers, as part of the first line of defence?
How do pathogens travel into the body?
- Direct contact - via bodily fluids
- Indirect contact - via hands, equipment, arthropods (flies, mosquitos), airborne
(respiratory droplets), ingested (water, food)
What are secondary invaders?
- These infections rely on there being an underlying primary problem.
- Many are caused by microbes already living on/in our own bodies
Immunocompromised patients can suffer infections with less common microbes
, Which type of people are more susceptible to infection?
- Elderly
- Very young
- Open wound or recent surgery
- Immunosuppressed
- Chronic disease
What are the different types of pathogens?
- bacteria
- virus
- Protozoa
- fungus
What does our microbe consist of?
- mouth
- lungs
- gut
- skin
- vagina
What are the routes of entry of microbes?
- Wounds (cuts, post surgery)
- Mouth
- Nose
- Eyes
- Ears
- Vagina
What is the 1st line of defence?
