These structures lie within the erythrocyte cytoplasm and are the result of modification of the red cell by the parasite. The structures differ from the dots seen in ethrocytes infected by ''P.vivax'' or ''P.ovale'' since they are few in number (you could imagine being able to count them). They are not seen in early trophozoites so define the late trophozoite stage. <br /> <br /> <br /> <br /> &lt;gallery mode=&quot;nolines&quot; widths=250px heights=250px&gt;<br /> File:Maurer1.jpg|link={{filepath:Maurer1.jpg}}<br /> &lt;/gallery&gt;<br /> &lt;span style=&quot;font-size:80%&quot;&gt;The most frequent form - two early trophozoites of ''P.falciparum'' in a single erythrocyte&lt;/span&gt;<br /> &lt;br clear=all&gt;<br /> <br /> ----<br /> <br /> &lt;span style=&quot;color:navy&gt;'''Species significance'''&lt;/span&gt; <br /> <br /> Maurer's dots and clefts are restricted to ''P.falciparum'' and can be distinguished from Schüffner's dots of ''P.vivax'' or the James' dots of ''P.ovale'' by their blue-grey colour, higher density and sometimes elongated (clefted) shape. <br /> ----<br /> <br /> &lt;span style=&quot;color:navy&gt;'''Compare with:'''&lt;/span&gt;<br /> <br /> &lt;gallery mode=&quot;nolines&quot; widths=200px heights=200px&gt;<br /> File:Maurer2.jpg|A.
