Helminth recovery and count

Animals were humanely euthanized following AVMP Guidelines [1] and necropsied 7–12 days after treatment administration for parasite recovery and count. The contents of the whole gastrointestinal tract (stomach, small and large intestines) including scraped mucosa were washed over appropriately sized sieves to remove debris, and examined for helminths. Worm counts were made on total gastrointestinal contents. Helminths were identified to species/genus, and stage, as appropriate, according to their morphology. The number of scolices was counted for cestode numeration.
