Answer: The 3
fixatives used in decal transport are:
10% formalin: This
fixative is appropriate for helminth eggs, and larvae, and for
protozoan cysts, oocysts and spores.
Schaudinn's
fixative: This fixative is present in PVA resin, used to
preserve protozoan cysts and trophozoites for the preparation of
permanent slides.
MIF
(Merthiolate-Iodine-Formaldehyde): This fixative is used
to concentrate the stool sample prior to microscopic analysis for
studying the parasites present in the stool sample. The
concentration of stool is important because there is less chance of
finding the presence of the actual parasite.
