serve as “dumps” for non-mature stages of a parasite in which they can accumulate in high numbers

Answer 2

Paratenic hosts

Question 3

parasite does not develop further to later stages

Answer 3

Paratenic or transport host

Question 4

one that is infected by a parasite, and which serves as a source of infection for humans or another species

Answer 4

Reservoir host

Question 5

Difference between Paratenic and Reservoir

Answer 5

1. no development takes place in paratenic hosts,whereas in reservoir host development and multiplication takes place
2. reservoir host is a primary host host, whereas paraatenic host serves as ‘dumps” for non-mature stages of a parasite which they can accumulate in high numbers

Question 6

is one that, though infected, is not necessary for the survival development of the parasite

Answer 6

Incidental or Accidental host

Question 7

a host represents a patch of habitat that provides metabolic resources or a protected environment in which to remain dormant

Answer 7

Parasites

Question 8

Microscopic Parasites/ Classification of Parasites

Answer 8

1. parasitic diseases are long term diseases
2. types of parasites are often described according to their movement and development
   (phone)
3. to a parasite, a host represents a patch of habitat that provides metabolic resources or a protected environment in which to remain dormant. Since these resources are finite, and the host itself
