P. falciparum
P. vivax
P. ovale
P. malariae
P. knowlesi
simian malaria widely common in Malaysia
P. knowlesi
Intermediate Host for malaria
human
Definitive host for malaria
Female Anopheles mosquito
Malaria infective stage
sporozoites
Diagnostic stage of malaria
ring stage of trophozoites & gametocytes
Plasmodium vivax and Plasmodium ovale are known as
hypnozoites
male gametocytes are known as
microgametocytes
female gametocytes are known as
macrogametocytes
which stage of parasites are responsible for the clinical manifestations (Erythrocytic or exo-erythrocytic )
Erythrocytic stage
The interval between the date of the infection and the time when the malaria parasites are detectable in the peripheral blood.
Pre-patent period
Period related to the first appearance of clinical symptoms of the disease
Incubation period
type of fever in P. vivax and P. ovale
Benign tertian fever
type of fever in P. falciparum
Malignant tertian fever
type of fever in P. malariae
quartan fever
daily fever / quotidian type of fever is seen in
P. knowlesi
gold standard for lab diagnosis
blood smear
type of stain used in Light Microscopy
Romanowsky stain (Leishman stain or Giemsa stain)
type of smear used to detect the presence of parasites
thick blood smear
type of smear used to identify the parasites
thin blood smear
