A WEC is used to identify infestation of common adult worm species including small (cyathastomins) and. large adult redworms (strongyles) and large roundworms (ascarids) in your horse. In most horses the. majority of the eggs we see will be from cyathastomin worms. WECs do not give an accurate assessment of encysted larvae, bots, pinworms or tapeworm. A one-off negative WEC does not guarantee the absence of a worm burden throughout the rest of the.
The worm in the picture is the large roundworm Parascaris equorum. No other equine roundworm reaches this size, so identification is easy.

At the age of four months, your filly is highly likely to harbour these worms.o other equine roundworm reaches this size, so identification is easy.
