disinfectants. It should be emphasized that rectal lavage using various anthelmintic products is very unlikely to have any effect, as O. equi does not inhabit the rectum or descending colon.
9.9. Bots Bots, though aesthetically displeasing, are very mild pathogens and should not dictate treatment decisions. However, the recommended baseline treatments include a macrocyclic lactone administered in the fall, which would help reduce bot occurrence. Recent data suggest variable efficacy of moxidectin against bot larvae (Reinemeyer et al., 2015), and ivermectin may be a more effective choice.
10. Six Changes Worth Making
• Check anthelmintic efficacy routinely by fecal egg count reduction testing.
• Do not deworm with fixed intervals year-round. • Abandon rotational deworming. • Reduce anthelmintic treatment frequency. • Tailor strongyle parasite control to the active transmission season. • Do not use fecal egg counts to diagnose clinical disease.
