Infectious Diseases
January 12, 2017
Infectious diseases and parasitic diseases cause a great burden on people around the world
especially people in low and middle income countries
Terminology
Infectious agent (instead of microorganism): cause of infection
Host: an organism larger than the infectious agent that provides shelter and nutrients, facility of
maturation, reproduction and spread
Infection: presence of an infectious agent in the body (internally)
Infestation: presence of an infectious agent on the body (externally)
Disease: a pathologial oditio of a part, orga, or sste of a orgais resultig fro arious
causes, such as infection, genetic defect, or environmental stress and characterized by an identifiable
group of signs or symptoms
Vector: an arthropod usually an insect (or an arachnid) capable of transmitting pathogens that cause
infectious disease, a vector is used as a vehicle that carries something
A brief review of the immune system
Any pathogen that fails to find a host will become extinct
Foreign invaders need to survive the first step entry

Immune system has several mechanisms (e.g. coughing, diarrhea, etc) to expel things right away
Immunity
Adaptive Immunity OR Innate immunity
Natural Adaptive Immunity OR Artificial Adaptive Immunity
Passive (maternal) OR active (infection) Passive(antibody transfer) OR active (immunization)
Functions of the immune system
Preventing infection or fighting it when it happens
Isolate or remove non-infectious molecules or substances
Remove altered self (e.g. damaged or malignant cells)
Recognition of self and tolerance is essential
Resources of the immune system
Innate (nonspecific) 1st line of defense OR adaptive (specific) 2nd line of defense protects/re-exposure
Cellular components OR humoral components
In the Immune prospective, the immune system knows you and will attack anything that is
foreig
Innate and adaptive/acquired systems work at the same time
Immune system is about learning, training, cooperation (innate and adaptive systems),
efficiency, following orders and rules, knowing when to stop (suppressor t cells) and
remembering (memory cells)
Mind like water, immune system responds as hard as the pathogen hits it
Innate immunity gets better with repeated encounters with the same pathogen.
A. True
B. False* - acquired immunity gets better
Among many functions, B cells are in charge of:
A. Killing viruses
B. Suppressing immune memory
C. Producing antibodies*
D. Triggering allergies
