Definitive Host
Where the adult parasite live, matures, or reaches sexual maturity
Intermediate host
Harbours larva, immature, or sexual stages of the parasite
Paratenic host
Like a babysitter or transport host
Endoparasite
Lives on the inside of the body
Ectoparasite
Lives on animal
Ovum or ova
Egg or eggs
Larva
Developmental stages between egg and adult
Microfilaria

Vector
Parasite that transmits diseases
Zoonosis
Disease that can be transmitted from animals to humans
Prepatent infection
Refers to parasitic infection That is not yet detected

Time between initial infection and detection
Transmammary
Route of infection where the parasite is passed through the mammary gland to the host’s offspring
Transplacental
Route of infection where the parasite is passed across the placenta to an animal in utero
Direct life cycle
Occurs when a parasite is passed directly from one host to another
Indirect life cycle
Occurs when a parasite ingests a paratenic or intermediate host to complete life cycle
Nematodes
