Total numbers of pigs displaying moderate (m) or high-grade (h) parasitic load assessed using the OT probe (1st run), categorized for different pathological lesions found. For each tissue section the quantity of trichomonads (m or h) was evaluated in context with their location (either within the intestinal lumen (lu), within crypts (c) or emigrating into the lamina propria mucosae (e)). Multiple entries are included and not shown separately.
| m/lu | m/c | m/e | h/lu | h/e | |
|---|---|---|---|---|---|
| Crypt hyperplasia | 4 | ||||
| ++–+++ non suppurative inflammation | 1 | 2 | 1 | 6 | |
| Crypt abscesses | 1 | 2 | 8 | ||
| Mucus-filled dilated crypts | 1 | 3 | 2 | ||
| No lesions | 2 | 1 |
Evaluation score: s: 0–3 parasites per high power field (hpf); l: 4–15 parasites per hpf; m: 16–40 parasites per hpf; h: >40 parasites per hpf.
