WEEK 2- Lab HOST- MICROORGANISN INTERACTIONS Flashcards
origin of the etiologic agent
or location from which it disseminates (e.g.,
water, food, insects, animals, other humans)
Microbial Reservoirs
means by which etiologic
agents are brought in contact with the human
host (e.g., direct and indirect transmission)
Mode of Transmission
Lists the Microorganism Sources
(Reservoirs)
Humans
Animals
Food (from plant and
animal sources)
Water
Air
Soil
Modes of Transmission
Direct transmission
Indirect transmission
transmitted by direct contact between reservoir and host
Direct transmission
transmitted to host via vectors and vehicles (inanimate objects)
Indirect transmission
Types of direct transmission
Horizontal transmission
Vertical transmission
