Microscopic diagnosis of Blastocystis hominis vacuolar forms in stool samples with Lugol's solution. Pathogenesis and blastocystosis discussed.
Blastocystis hominis (vacuolar form) is a conditionally pathogenic protozoan, previously considered a human commensal. Blastocystosis in immunocompromised individuals is called “Zierdt–Garavelli disease”. It is more often found in liquid stools and lyses in preparations with distilled water. Stool, Lugol’s solution, magnification x400+zoom.
