<span style=font-size:90%>'''Description'''</span>
<span style="font-size:90%>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.</span>


<span style="font-size:90%>'''Species significance'''</span>
<span style="font-size:90%>Pigment may vary in colour and may be clumped or scattered as individual small masses depending on species; in some instances this can help (most obviously in the central clump seen in the "daisy head" schizonts of ''P.malariae''). Generally however, the form of the pigment is less useful than other features in determining species.</span>
