Simple floatation Technique
Simple floatation / Will’s technique
-
Small floatation tube with emulsion of faeces in the above solutions is filled to its full capacity till a convex surface is formed and is allowed to stand for 20 to 30 minutes, by which time eggs would have floated up.
-
Apply a coverslip or slide to the surface to remove the first drop of fluid, containing eggs and then examine that drop on the slide.
-
It is worthwhile to remember that almost all cestodes, except the members of Cotyloda, do not discharge eggs, but gravid segments containing numerous eggs are shed and passed out.
-
Hence it is not always possible to find cestodes eggs in faecal samples.
