This photomicrograph of a fresh stool sample, which had been prepared using a 10% formalin solution, and stained with modified acid-fast stain, revealed the presence of four Cyclospora cayetanensis oocysts in the field of view. Compared to wet mount preparations, the oocysts are less perfectly round and have a wrinkled appearance due to this method of fixation. Most importantly, the staining is variable among the four oocysts.Created:

Plate 3. Alexandrium minutum. Fig. 1. SEM: ventral view. Cell small and ellipsoidal. Epitheca conical, larger than hypotheca. Hypotheca short and wide; antapex obliquely flattened. Intercalary bands present. Cingulum deep, lipped; displaced 1X its width. Sulcus shallow (sa=anterior sulcal plate). Apical pore plate (Po) in direct contact with 1' plate. Fig. 2. LM: ventral view. Ventral pore (vp) present on 1' plate. Fig. 3. SEM: apical view. Po large, narrow and oval; indirectly connected to 1' plate. Vp present (arrow). Figs. 4-5. Line drawing. Fig. 4. Ventral view. 1' plate slender and rhomboidal. Fig. 5. Po connection to 1' plate: a. direct; b. indirect via thin suture. Fig. 6. LM: cyst circular in apical view.
