FIG. 3.

Anatomical site, histology scores, and genotyping results of intestinal samples obtained from piglets at necropsy: piglet 1 (type 1 only); piglet 2 (type 2 only), piglet 3 (type 1 and type 2 challenge on day 0), piglets 4 and 5 (mixed infection with type 2 challenge on day 1), and piglets 6 and 7 (mixed infections with type 2 challenge on day 2). Piglets 1 through 3 were euthanized on day 5, piglets 4 and 6 were euthanized on day 4, and piglets 5 and 7 were euthanized on day 6. Sections are numbered consecutively from stomach to distal spiral colon (left to right). Histology scoring is as follows: 0, no parasites detected on intestinal villi; 1, few parasites detected; 2, 25% of villus surface covered by parasites; 3, 50% of villus surface covered by parasites; 4, 75% of villus surface covered by parasites; and 5, 100% of villus surface covered by parasites. S, stomach; SI, small intestine; LI, large intestine; ▨ band, intestinal sample positive for type 1 by COWP PCR-RFLP; ▪ band, intestinal sample positive for type 2 by COWP PCR-RFLP; and na, genotyping results not available.
