Kinds of Parasites

Question 1

Associated only with one species of host, or closely related hosts

Answer 1

Host/species specificity

Question 2

Each parasite species has its predilection site or on the host

Answer 2

Organ specificity

Question 3

Parasite that briefly visit their host to obtain nourishment but not dependent on them

Answer 3

Optional Occasional/Periodic Parasite

Question 4

Do not permanently live upon their host but are dependent upon them for nourishment

Answer 4

Obligate Occasional Parasite

Question 5

Parasitism is limited to stage/s in their life cycle

Answer 5

Determinate transitory

Question 6

Parasitism extends from the time of hatching of the egg to the time that the eggs are produced by the adult

Answer 6

Permanent parasite

Question 7

Cannot pass spontaneously from one host to the other e.g HELMINTHS

Answer 7

Fixed Parasite
