Eggs of large strongyles are generally
smaller than those of small strongyles,
but the different groups are not
distinguishable without detailed
measurements. The same applies for
Trichostrongylus axei. Faecal sample
must be cultured to obtain third-stage
larvae (L3) for further differentiation.
Longitudinal oval, thin-shelled eggs with smooth
surface and evenly rounded poles (strongyle type).
Dark, spherical blastomeres fill eggs only partially.
70-110 x 30-54 µm in size.
