CARRIER

an individual who is infested but has no symptoms of disease
|
|
|
HYPERPARASITE
|
a parasite which parasitizes another parasite
|

|
|
|
ECTOPARASITE
|
a parasite that lives on the outside of the body
|
|
|
INFECTION
|
occurrence of parasites in a host (which is not necessarily manifested by disease). A host is infected by endoparasites
|

|
INDIRECT LIFE CYCLE
|
a life cycle which requires one or more intermediate hosts before the definitive host species is reinfected. contrast - DIRECT LIFE CYCLE
|

DIOECIOUS

INFESTATION
|
occurrence of parasites on a host (which is not necessarily manifested in disease). A host is infested by ectoparasites

an inflammatory condition of the skin characterized by redness, itching and vesicular lesions which become crusted, scaly or hardened
|
|
|
HEMATOPHAGIA

the act of subsisting on the blood of another animal
|
|
|
FIRST INTERMEDIATE HOST
|
the first host parasitized by the larval stages of the parasite
|
|
|
DIRECT LIFE CYCLE
|
a life cycle in which a parasite is transmitted directly from one host to the next without an intermediate host or vector or another species. contrast - INDIRECT LIFE CYCLE
|
|
|
DERMATITIS
|
inflammation of the skin
|
|
|
DISEASE
|
the debilitating effects of infection by a parasite (pathogen) on a host

|
ENDOPARASITE

|
|
HYPERKERATOSIS
|
a hypertrophy of the corneous layer of the skin
|
|
|
IMMUNITY
|
1) a state in which a host is not susceptible to infection or disease
2) the mechanisms by which this is achieved. Immunity is achieved by an individual through one of three routes: natural or innate immunity genetically inherited or acquired through maternal antibody, acquired immunity conferred after contact with a disease and artificial immunity after successful vaccination |
