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.
Any or all of these parasites may be present in the horse at one time, but they may be at different stages in their life cycles. Some worm species can lay hundreds of thousands of eggs per day, so parasite loads can grow quickly both on pasture and in horses. The different dewormers have varying effectiveness against the types and stages of parasites. Intelligent control of parasites must take all these factors and many others into account.
