Sepsis Flashcards
What are the gram negative organisms that can cause infection?
Wet and warm
Bacilli I.e. rods:
E.coli Salmonella Klebsiella Pseudomonas Campylobacter Legionella Proteus Bacterioids
Cocci I.e. thin spheres:
Neisseria
Gonorrhoeae
What are the gram positive organisms that can cause infection?
Dry and cold
Bacilli, rods:
Listeria
Clostridium
Cocci, spheres:
Staphylococci
Streptococci
What is a yeast?
A single cell fungus
Reproduces by budding
Often form bio films
What is a mould?
A fillamentous fungi, produces spores
What is a dimorphic fungi?
One that can grow as a yeast or as a mould depending on temperature
What are the two categories of parasite?
Ecto parasite - lives ON the host (skin and hair)
Endo parasite - lives IN the host (mucosal surfaces)
- Helminths = worms
- Protazoa = single cell
What are non-fermenter bacteria?
Those that don’t use ferment sugars, they form rapid biofilms and are hard to treat
How is streptococci classified?
Beta, alpha or gamma haemolytic
Whether it completely (beta), incompletely (alpha) or doesn’t haemolyse blood
Most commonly affects URT, Urinary tract, lungs and skin.
What is sepsis?
Life threatening organ dysfunction due to dysregulated host response to infection.
Septic shock indicates a deterioration of sepsis, meaning profound circulatory, cellular and metabolic deterioration.
Remember to make connections in sepsis, e.g. why are we worried about someone who has had CRC or someone who has CKD stage 4?
They may have a colostomy or indwelling lines or peritoneal access respectively - all are risk factors for sepsis
