30
Q

Microscopic examination of PBF By what ??

A

giemsa stained thick and thin blood flims

31
Q

thick film Dx ?

A

presence of parasite

32
Q

thin film Dx ?

A

confirm the Dx
identify species
quantify parasite load

33
Q

how to quantify parasite load ?

A

by counting the % of infected erythrocytes

34

Gametocytes of P f shape ?

A

crescent / banana

35
Q

other P - gametocytes shape ?

36

histidine rich protein-2
HRP-2

40
Q

Importance of HRP-2 ?

A

-identification of Falciparum
-monitoring Tx - after 2weeks of anti-malarial Tx - HRP-2 result ——
-non falciparum malaria = HRP-2 = (-)

41
Q

when detecetion of malarial parasite in blood film is difficult ?

A

when taken from anti-malarial drug

in case of primary infection – (2-3) days

when blood films are taken during the apyrexial period of Pf

42

why P f more severe ?
499

A

P f invade red cells of all ages

parasitemia is very high in Pf

H+N – cerebral M
occlusion of the capillaries

shows resistance to common anti-malarial drugs

45
Q

what is Premunition ?

A

partial immunity based on humoral AB that block merozoites from invading the red cells occurs in infected individuals
