RDT Quiz A Q2


During the trophozoite stage of parasite growth there are many changes to both parasite and the red cell it is contained in. All species dorm malarial pigment (haemozoin) as they develop as it is essential to their safe development.

Which of the following are true of malarial pigment? (select one or more options)

It is formed as part of "haem" digestion
It is formed as part of "globin digestion"
P.malariae does not form pigment
Iron is an important part of malaria pigment
Pigment may also be found in phagocytes
It is most obvious in early trophozoites


Explanation of correct answer (click "Expand")
Short answer taken from section "Malaria Biology - Malaria Pigment" (see the section for full details and links).

During their development malarial parasites metabolise the haemoglobin within erythrocytes to support their growth. Evetually infected cells at late stages of parasite development red cell may have no visible haemoglobin. As part of that process the parasite must "detoxify" the iron component of the haem element. This process creates a detoxified iron containing protein "haemozoin" which is visible as pigment - as you might expect this is most visible at late stages of parasite development. When schizonts rupture to release their daughter parasites, the pigment is also released and is takn up by phagocytes.
