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.
