Giardia cysts stained with hot carbolfuchsin were used as internal controls in a concentration method for surface
water samples. The morphological integrity of stained cysts and the stain's stability and intensity were tested
with each of the chemical reagents used in the aluminum sulfate flocculation method. No alterations in morphology
or color were noted. The stained cyst preparation has a low cost, high stability, and suitability for both
light and immunofluorescent microscopy, making it affordable to researchers in low- and middle-income
countries.
