There are many different species of ''Isospora'', all of which are host specific.  The most commonly seen of all the ''Isospora'' species is ''Isospora suis''.

===Identification===
 +
Each oocyst measures 20-50μm.  The eggs are subspherical, and the wall is colourless and thin.  When sporulated each one contains two sporocyts each with four sporozoites.

The next step is '''Schizogony'''.  This is an asexual process which occurs endogenously.  After the sporozoites invade the epithelia, they then form trophozoites.  These trophozoites then form merozoites, which is known as merogony.

Gametogony then occurs, which is sexual division occurs endogenously, namely the intestinal cells. Merozoites then form either microgamonts (male) or macrogamonts (female).  Invasion of macrogametocytes containing cells by microgametocytes leads to fertilization, and the cycle continues.
