Ectoparasites

live on the organism or host which they need to survive

Endoparasites

live within the organism or host which they need to survive

Arachnida

class of the phylum arthopoda consisting of ticks, mites and spiders

Arthopoda

phylum consisting of most ectoparasites

Cestodes

tapeworms

Deworm

term for treatment to kill worms in animals

Direct Contact

host comes into contact with another animal and gets the parasite

Direct Life Cycle

no intermediate host to complete the life cycle

Fomite

an inanimate object

Helminth

a parasitic worm

Hermaphrodite

male and female in one body

Indirect Life Cycle

needs an intermediate host to complete the life cycle

Insecta

class of arthropods that have 3 distinct regions to their body

Intermediate Host

host where the parasite resides and doesn't fully develop and is essential for the completion of the life cycle

Latent Infection

the animal is infected, but there is no clinical signs; infection is dormant but has potential to become active

Mammary Migration

parasitic larva are passed from mother to neonate through the milk

Mucosal Migration

larva migrate into the intestinal mucosa, go through maturations and come out

Nematode

a roundworm; a member of class nematoda

Ocular larval migrations

lesions on retina of the eye caused by ingestion of parasite eggs whose subsequent migrating larva reach the eye

Occult Infection

those that are hidden or hard to detect such as heartworm

Paratenic Host

a host where the parasite resides but does not develop and which is not physiologically essential for the completion of the life cycle

Patent

when a causitive agent can be detected by some means

Prepatent Period

the time after infection until ova are present in the feces and the infection can be diagnosed

Rhabdidiform

free living; lives outside the host

Somatic

refers to body tissues

Somatic Migration

larva migration route takes them into the body tissues where they encyst or encapsulate so that the body's antibodies cannot attack them

Sylvatic

found in wild animals

Tracheal Migration

larva migration route takes them through the lungs, up the trachea and swallowed back down into the GIT

Transplacental Migration

larva pass through the placenta from mother to fetus

Trematode

fluke

Vector

a carrier of disease from one host to another

Verminous

pertaining to or caused by worms

Visceral Larva Migrations

disease caused by somatic migration of parasite through a paratenic or intermediate host that leads to debilitating lesions in the viscera

Zoonotic

transmission of animal diseases to man
