Question 9

Define Facultative and Obligated parasite

Answer 9

Facultative : an organism that lives independently of host and is occasionally pathogenic
Obligate : an organism that can’t lead an independent non - pathogenic life

Question 10

Define Poliferating non - Poliferating parasites

Answer 10

Poliferating : parasites that have the ability to increase in number on/in the body of the person they settle on/in
Non-poliferating : parasites that don’t have the ability to increase in number in/on the host they settle on

Question 11

Define Zoophilic and Anthropophillic parasites

Answer 11

Zoophilic : parasites that can use man/ animal as host but prefers animals
Anthropophillic : parasites that can use man/animal as host but prefers man

Question 12

Define Endoparasite and Ectoparasite

Answer 12

Endoparasite : parasite that settles in the body of a host
Ectoparasite: Parasite that settle outside of the host’s body

Question 13

Differentiate between short-term, long-term and medium-term parasites

Answer 13

Short-term : parasite that is independently mobile and only has contact with host for short periods of time to feed
Medium-term : parasite that settles in/on man to complete its larval stages
Long-term : parasite that, once it settles in man, it spends the rest of its life there

Question 14

Differentiate between 1, 2 and 3- host parasite

Answer 14

1 host : uses man as a host
2 hosts : uses man + animal
3 hosts : one man + 2 animals

Question 15

Define man compromised and non-man compromised parasites

Answer 15

Man compromised : parasite that is so dependent on man that in order to survive, it has to settle on man at one point in its cycle (specific with areas it settles on)
Non-man compromised : parasite that may occasionally settle in/on man but man isn’t an important link in their life-cycle (no preference for particular areas of the body)

Question 16

Differentiate between slightly pathogenic, pathogenic and life threatening

Answer 16

Slightly pathogenic - causes little damage and no visible symptoms
Pathogenic : causes visible damage, not life threatening even when in large numbers
Life threatening : affects man’s health so much, it causes severe illness or deathb
