inflammation of a mucous membrane
DEFINITIVE HOST
the host that harbors the adult stage of the parasite
CARRIER

INFECTION

INCIDENTAL PARASITE
a parasite in a host in which it does not usually live
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
