Infectious Disease Flashcards
Bacteria that can kill: MRSA
- Type of staph bacteria passed on through skin to skin contact
- Can also be spread through bed linens, bathroom fixtures and medical equipment
Bacteria that can kill: C.Difficile
- Bacteria found in human feces
- Can be passed on if a person touches an infected surface and then proceeds to tough their mouth
Bacteria that can kill: CRE
- Bacteria found in the bowels and the feces
- Typically affect patients using rentilators, urinary catheters and intravnous catheters
Bacteria that can kill: Enterococci
- Found in the intestines and female gential tract
- Infection is spread through person to person contract
Syndrome Ontario
Pathogens→Syndromes and Diseases→ 1) Recover, no longer infected 2) Survive 3) Die

Classifications of Agents of Infections
Bacteria, Viruses, Protozoa, Fungi, Parastic worms, Prions
Hemagglutinin
Allows virus to enter host’s cells
Neuraminidase
Allows virus to escape host’s cells
Parasites
Malaria is caused by a single-cell parasite called Plasmodium which is transmitted via the bites of an infected mosquito
Prions Symptoms
- Abnormal behaviour
- Loss of coordination
- Progressive dementia
