1

Describe the various parasitic infections

- Entamoeba histolytica = BRAIN ABSCESSES
- Trypanosoma brucei (african trypanosome) = SLEEPING SICKNESS

- Acanthamoeba, Naegleria and balamuthia (normally reside in fresh water
- All three organisms can cause FATAL INFECTIONS OF THE CNS

3

Zoonoses

disease of vertebrate animals that can be transmitted to man; either directly or indirectly through an insect vector

4

Arboviral

disease caused by insect vector

5

consequences of bacteremia

- transient and benign
- sepsis and septic shock (including toxic shock)
- endocarditis

6

Sepsis

- systemic inflammatory response syndrome (SIRS) that has a proven or suspected microbial etiology
- Not that bacteremia is NOT required and can be caused by toxins released by bacteria

7

SIRS

two or more of the following conditions are met:
- FEVER or Hypothermia
- Tachypnea
- tachycardia
- abnormal wbc count (leukocytosis or leukopenia)

8

Severe sepsis

sepsis with one or more signs of organ dysfunction
- examples: reduction in urine output, mental status changes, systemic acidosis, hypozemia

9

Septic shock

Severe sepsis + HYPOTENSION (systolic pressure < 90mmHg)

10

Refractory septic shock

- septic shock that lasts for >1 hour and does not respond to fluid and pharmacologic treatment

11

Multiorgan failure

Dysfunction of more than one organ and may development of disseminated intravascular coagulation (DIC)
