PARASITOLOGY Flashcards
process of living together of 2 diff. species
symbiosis
one organism gains but the other is unharmed/affected/nor helped
commensalism
reciprocal benefit
mutualism
one gains and other suffers from the relationship
parasitism
- lives inside the body
- presence in host connotes infection
endoparasite
- lives outside the body
- presence in host connotes infestation
ectoparasite
type of parasite that needs a host to complete development and propagation
obligate parasite
type of parasite that may exist in a free-living state but becomes parasitic when the need arises
facultative parasite
type of host in which the adult/sexually mature stage of the parasite lives
definite/final host
type of host in which the parasite lives during a period of its larval/asexual development
intermediate host
reservoir of infection in transmitting the parasite without undergoing any development inside this host
paratenic host
allow life cycle to continue and become additional sources of human infection
