title: Does examination of fecal samples 24 hours after cestocide treatment increase the sensitivity of Anoplocephala spp. detection in naturally infected horses?
abstract: Fecal samples were examined immediately before and 24 to 48 h after cestocide treatment for a comparative detection of tapeworm-positive horses. In early winter, 17 weanlings, 20 yearlings, 15 2-year-old horses, 24 breeding mares, and 2 stallions were treated with praziquantel in combination with a macrocyclic lactone. The horses were presumed to be naturally infected with tapeworms after pasture grazing. Fecal samples were collected before treatment (Day 0), at 24 or 48 h after treatment (Day 1-2), and 16 to 21 d after treatment (Day 16-21). A Wisconsin test was done on all fecal samples. Odds of detection of infection for all age groups increased by a factor of 2.04 [95% confidence interval (CI): 1.30 to 3.20] from Day 0 to Day 1-2 (P = 0.002).
