BASIC CONCEPTS IN MED PARA

Question 1

Even though revolutionary advances in transportation has made geographical isolation no longer a protection against many of the parasitic diseases, many of them are still found in abundance in the tropics.

Answer 1

geographical distribution

Question 2

Distribution of parasites depends upon:

Answer 2

a. The presence and food habits of a suitable host:
b. Easy escape of the parasite from the host-
c. Environmental conditions favoring survival outside the body of the host,
d. The presence of an appropriate vector or intermediate host

Question 3

the route followed by a parasite from the time of entry to the host to exit, including the extracorporeal (outside the host) life.

Answer 3

life cycle of parasites

Question 4

infection is the result of entry and development within the body of any injurious organism regardless of its size.h

Answer 4

host parasite relationship

Question 5

a perfect host parasite relationship where tissue destruction by a parasite is balanced with the host’s tissue repair.

Answer 5

Carrier state -

Question 6

this is due to an imperfect host parasite relationship where the parasite dominates the upper hand. It can result either from lower resistance of the host or a higher pathogenecity of the parasite.

Answer 6

disease state

Question 7

occurs when the host takes the upper hand. Laboratory diagnosis - depending on the nature of the parasitic infections,

Answer 7

parasite destruction

Question 8

the following specimens are selected for laboratory diagnosis:

Answer 8

blood
stool
urine
sputum
biopsy material
Urethral or vaginal discharge

Question 9

many parasitic infections can be cured by specific chemotherapy.

Answer 9

treatment

prevention and control
