the study of HOST - PARASITE relationship
Parasitology
the study of PARASITES which infect HUMANS
Parasitology
an animal or plant on or in which a parasite or commensal organisms lives
Host
A ____ is an organism that lives in another organism, called the ____, and often harms it uses the host to gain strength, and the _____ loses some strength as a result
Parasite
Host
Host
“feeding, fattening” or “one who eats at the table of another”
Parasitism
Association of Living Organism
Symbiosis
3 Symbiosis
Mutualism
Commensalism
Parasitism
any organism that lives in or on the body of another organism in order to survive
Parasite
any organism that harbors a parasite
Host
an association between organisms of two different species in which each is benefited
Mutualism
“work together” each benefiting from the relationship
Mutualism
an association between individuals of two species in which one species obtains food or benefited from the other without either harming or benefiting the latter
Commensalism
a form of symbiosis in which one organism benefits at the expense of other organism (parasite) usually on different species (host)
Parasitism
may lead to the injury of the host
Parasitism
5 Host Classification
Definitive host
Intermediate host
Reservoir host
Accidental host
Paratenic host
adult form of the parasite, sexually mature form
Definitive host
asexual or larval form
Intermediate host
organism in which the parasite is harbored until transmitted to the main or primary host
Reservoir host
alternate host or passive carrier of a pathogenic organism
Reservoir host
infection with parasite not normally found on the host
Accidental host
animal acting as substitute intermediate host of a parasite, usually having acquired the parasite by ingestion of the original host
Paratenic
4 Parasite Classification
Based on habitat
Based on area/location
Based on relationship between host - parasite
Based on transmission
Based on habitat
Ectoparasite - attach into the skin like lice
Endoparasite - within/inside the body
can live and multiply in the moist
ex: protozoans
Capnophilic
