In addition, these systems do not appear to address the different sizes (2-6 m) of Cryptosporidium during this parasite's life-cycle which has several developmental stages: (i) motile zoite or merozoite, set free from ruptured schizonts; (ii) schizont, containing 8 merozoites when mature; (iii) mature merozoite; (iv) macrogametocyte.
The most heavily infected tissue was the adductor muscle, containing large clusters of zoites in necrotic areas of individually infected muscle cells and inside hemocytes (Kristmundsson et al.
