Overview Flashcards
What do you call the relationship of living together of unlike organisms?
Symbiosis
This is when two species live together and one species benefits from the relationship
Commensalism
This is when 2 organisms benefit from each other
Mutualism
This is a relationship where 1 organism lives in or on another, depending on the latter for its survival.
Parasitism
What is the parasite that lives inside the body of the host?
ENDOparasite
What is the parasite that lives outside the body of the host?
ECTOparasite
A parasite that needs a host at some stage of their life cycle.
Obligate parasite
What parasite may exist in a free living state?
Facultative parasite
What parasite establishes itself in a host where it does not ordinarily live?
Accidental/Incidental Parasite
This parasite remains in the body of host for its entire life.
Permanent parasite
A parasite the lives on the host for short period of time.
Temporary parasite
What parasite passes through the digestive tract without infecting the host?
Spurious/Caprozoic parasite
The host where parasites attain sexual maturity.
Definitive host/Final Host
What host harbors the asexual or larval stage of the parasite?
Intermediate host
The host where the parasite does not develop further to later stages.
Paratenic host
This harbors the parasite, and allow the parasite’s life cycle to continue and become an additional source of human infection.
Reservior
What harbors the parasite where it is not its usual host?
Incidental host
What vector that only transports the parasite?
Mechanical parasite
What type of vector that transmits parasite only after it has completed the development within the host?
Biologic vector
What do you call the time between the infection and evidence of symptoms?
Incubation period
What do you call the time between the infection or acquisition of parasite and evidence of infection?
Pre-patent
This happens when an infected individual becomes his own direct source.
Autoinfection
What do you call when the infected is further infected?
Superinfection
What harbors the pathogen without signs and symptoms?
Carriers
