What is the definitive host?
where sexual reproduction occurs
What does PPP stand for and what is is?
Prepatent period
Time from when animal consumes infectious stage to the time you can begin diagnostic testing
What is a direct life cycle?
one host is required to complete the life cycle
What is an indirect life cycle?
two or more hosts are required to complete a life cycle
What is arrested development
When Immune System is strong parasite hids in tissues until IS is low
What is an aberrant host?
incorrect host
Endoparasites infect the host internally
Infection
Ectoparasites attach to or occupy the host
Infestation
Preferred site in or on the host
Predilection site
Site in or on a host which is not a normal location
Aberrant site
The mechanism of how a disease develops
Pathoenesis
List some factors that determine clinical signs in a patient:
- previous exposure
- Type of host response
- nutritional status
- age of host
- stress of host
- health of host
What does the suffix -iasis mean?
presence of a parasite
What does the suffix -osis mean?
disease caused by parasite
Host in which the parasite is unable to complete the life cycle development
Aberrant/Dead end host
host in which the parasite is not commonly found, but the host is suitable for parasite development
Accidental host
Host which harbors the adult or sexual stage of the parasite
Definitive host
Host in which a larval or immature stage of the helminth parasite develops before becoming infective to the final or definitive host.
Intermediate host
The host in which larval stages of a helminth parasite do not develop further
Paratenic or transport host
