| The demonstration
of eggs or larvae in faeces can indicate the presence of parasitic
infection and facilitate the diagnosis of parasitic disease.
The eggs and larvae can be identified and quantified.
For this purpose faecal material can be processed by:
- making a direct smear
on a microscope slide for preliminary egg identification
N.B. In the examination of poultry, faecal samples cannot be taken directly from the cloaca. If assessment of individual birds is required they should be caged separately and the fresh droppings collected.
If individual bird assessment is not required then the fresh droppings can be collected from the house or pen.
- a flotation technique
to concentrate eggs and separate them from debris for identification
and counting
- faecal culture to
hatch the eggs and develop the larvae to the third
stage for identification
