Deoxynivalenol (DON) and zearalenone (ZEN) are among the most important mycotoxins. The aim of the study was to examine the effects of low doses of these mycotoxins on the histological structure and ultrastructure of the large intestine in the pig. The study was performed on 36 immature gilts of mixed breed (White Polish Big \u00d7 Polish White Earhanging), which were divided into four groups administrated per os with ZEN at 40 \u00b5g\/kg BW, DON at 12 \u00b5g\/kg BW, a mixture of ZEN (40 \u00b5g\/kg BW) and DON (12 \u00b5g\/kg BW) or a placebo. The pigs were killed by intravenous overdose of pentobarbital after one, three, and six weeks of treatment. The cecum, ascending and descending colon samples were prepared for light and electron microscopy. Administration of toxins did not influence the architecture of the mucosa and submucosa in the large intestine. ZEN and ZEN + DON significantly decreased the number of goblet cells in the cecum and descending colon. The mycotoxins changed the number of lymphocytes and plasma cells in the large intestine, which usually increased in number. However, this effect differed between the intestine segments and toxins. Mycotoxins induced some changes in the ultrastructure of the mucosal epithelium. They did not affect the expression of proliferative cell nuclear antigen and the intestinal barrier permeability. The obtained results indicate that mycotoxins especially ZEN may influence the defense mechanisms of the large intestine.<\/jats:p>","DOI":"10.3390\/toxins10040148","type":"journal-article","created":{"date-parts":[[2018,4,4]],"date-time":"2018-04-04T06:45:37Z","timestamp":1522824337000},"page":"148","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":38,"title":["The Effects of Deoxynivalenol and Zearalenone on the Pig Large Intestine.
