Parasitology Exam 1 and answers
Ectoparasite✔✔Reside on the external surface of their host, causing infestations
Endoparasite✔✔Reside inside the host's body leading to infections
Autogenic✔✔Complete their life cycle in a single ecosystem
Allogenic✔✔Complete their life cycle in more than one type of ecosystem
Microparasite✔✔Small and have rapid generation times; difficult to quantify
Macroparasite✔✔Larger, though small er than their host; can be quantified
Obligatory✔✔Requires a suitable host to complete its life cycle
Facultative✔✔Can adopt a parasitic existence but also have a free-living version of
itself
Opportunistic✔✔Take advantage of certain circumstances to initiate an infection in a
host they don't normally infect
Biological Vector✔✔Parasites develop or multiply before it is successfully
propagated to a new vector
Mechanical Vector✔✔Simply transfer a parasite to a host
Hyperparasite✔✔Parasites of parasites
Parasitoid✔✔Organisms that spend a significant amount of time on or within a single
host; often sterilize of kill their host
Cleptoparasite✔✔Steal of scrounge food obtained by another organism
Social Parasite✔✔Invade or lay eggs in the nest of a host organism and develop on
food provided in the nest
Definitive Host✔✔Host in which parasites can reach "sexual" maturity
Intermediate Host✔✔Parasite undergoes a needed developmental step in this host
and may even asexually reproduce, but "sexual" maturation does not take place
Accidental Host✔✔Accidentally infected and are not normal hosts to the parasite
Paratenic Host✔✔Nonessentail host that increases the chance of transmission to the
definitive host; parasites do not replicate; fills ecological gab between intermediate
and definitive host
Ectoparasite✔✔Reside on the external surface of their host, causing infestations
Endoparasite✔✔Reside inside the host's body leading to infections
