A

MALARIA

36
Q

FOUR PROTOZOAL PARASITES

A

Plasmodium falciparum
Plasmodium vivax
Plasmodium malariae
Plasmodium ovale

37
Q

s considered to be the most dangerous type of protozoan

A

Plasmodium falciparum

38
Q

causes a milder form of the disease, which seldom results in
death.

A

Plasmodium vivax

39
Q

is endemic in many tropical countries and causes very mild
signs and symptoms in the local population

A

Plasmodium malariae

40
Q

which is rarely seen, seems to be in the process of being
eradicated.

A

Plasmodium ovale

41
Q

are usually given in com bination form to attack the Plasmodium

A

ANTI-MALARIALS

42
Q

ANTI-MALARIALS drugs can be:

A

schizonticidal
gametocytocidal
sporonticidal
schizonts as prophylactic and antirelapse agents

43
Q

-acting against the red-blood-cell phase of the life cycle,

A

schizonticidal

44
Q

-acting against the gametocytes

A

gametocytocidal

45
Q

acting against the parasites that are developing in the mosquito

A

sporontocidal

46
Q

work against tissue

A

chizonts as prophylactic or antirelapse agents

47
Q

is currently the mainstay of antimalarial therapy

A

Chloroquine

48
Q

directly toxic to parasites that absorb it; it is acidic, and it decreases the ability of the parasite to synthesize DNA, leading to a blockage of reproduction.

A

Chloroquine

49
Q

increases the acidity of plasmodial food vacuoles, causing cell rupture and death.

A

Mefloquine

50
Q

disrupts the mitochondria of the Plasmodium, causes death of gametocytesan d prevents other forms from reproducing.

A

Primaquine

51
Q

is used in combination to suppress malaria; it acts by blocking the use of folic acid in protein synthesis by the Plasmodium

A

Pyrimethamine

52
Q

inhibits nucleic acid synthesis, protein synthesis, and glycolysis in P. falciparum

A

Quinine
