PARASITE
organisms that harbor the parasite & provide its nourishment
HOST

SYMBIONT
parasite deprive the host of essential nutrients
PARASITISM
live outside of host body (fleas, lice)
ECTOPARASITES
invasion of the body by ectoparas
INFESTATION
inside the body of host (helminths or worms)
ENDOPARASITES
invasion of the body by endoparas
INFECTION
must exists as parasite inside a host (plasmodium, hookworms)
OBLIGATE PARASITE
can live independently; free - living
FACULTATIVE PARASITE
remain in a host from early life to maturity
PERMANENT PARASITE
simply visit the host during feeding time
INTERMITTENT PARASITES
becomes fixed in an unusual organ different from where it is ordinarily parasitized
ERRATIC PARASITES
wandering parasites infects host where it cannot develop any further
ABERRANT PARASITES
harbors the adult stage or sexual stage
DEFINITIVE HOST
harbor larval or asexual stage
INTERMEDIATE HOST
serve as means of transport (example: vectors)
PARATENIC HOST
vertebrate hosts which harbor parasite & act as source of infection in man
(example: pig for balantidium coli)
RESEVOIR HOST
parasite cannot complete its life cycle.
DEAD-END HOST
no movement
SPOROZOA
(amoebas); no feet
