area of microbiology concerned with invertebrate organisms capable of producing diseases in humans
Stages of development that a parasite goes through during its life includes growth and development reproduction and transmission routes
the stage of the parasite at which it is capable of entering the host and continuing development within the host
the stage at which a parasite may be detected in human body secretions, discharges, feces, blood or tissue by chemical means or microscopic observation as an aid to diagnosis
Accidental (or incidental) host
infection of a host other than the normal host species; a parasite may or may not continue full development in an accidental host.
the association of 2 different species of organisms in which one partner is benefited and the other is neither benefited or injured
the animal in which a parasite passes its adult existence, sexual reproductive phase, or both
an organism capable of living an independent or a parasitic existence; not an obligatory parasite, but potentially parasitic
the species of animal or plant that harbors a parasite and provides some metabolic resources to the parasitic species
the animal in which a parasite passes its larval stage or asexual reproductive phase
the association of 2 different species of organisms in which the smaller species lives on or within the other and has a metabolic dependence on the larger host species
an animal that harbors a species of parasite that is also parasitic for human and from which a human may become infective
the association of two different species of organisms exhibiting metabolic dependence by their relationship
any arthropods or other living carriers that transport a pathogenic microorganism from an infected to a non-infected host
a disease involving a parasite that has accidentally infected a human; the normal host for the parasite is an animal
Indirect life cycle
other rhabditiform larvae may molt into free-living males and females, female lay eggs that hatch into filariform larvae
