Harbors adult, mature, or sexual stage of parasite.
Harbors larval, immature, asexual stage of parasite
Paratenic/ Transport Host
2nd host, not required for completion of life cycle.
Give two examples of parasites that have an intermediate host, name the host.
- 1.) Heartworms- mosquitos
- 2.) Taenia tapeworms- fleas
Requires a host to develop.
Most of life cycle free living
Parasite not normally found in host, or in host feces
Damage to the host and clinical signs of the host are dependent upon:
- Age of host
- Health of host
- Pathogenicity of parasite
- Life cycle stage of parasite
- # of adult parasites
- duration of infection
What are the three types of transmission of parasites?
- 1.) Direct contact
- 2.) Fomite contamination
- 3.) Arthropod borne
List examples of how parasites can be spread by direct contact.
- Oral ingestion of infective stage
- Sexual contact
- Skin penetration
- Lungs- inhaling parasite
- Physical closeness
List examples of fomites that can be sources of parasite transmission.
Tack, food bowls, litterbox, chew toys, needles
Arthropods that trasmit infection
Diagnosis of parasites is based on:
- Clinical signs
- Knowledge of life cycle of parasite
- Presence of adults in vomitus or feces
- Presence of eggs in feces
Direct vs Indirect life cycles
Direct does not require an intermediate host, indirect does.
