摘要:

旨在探讨镰刀菌毒素对断奶仔猪肠道IL-1β和IL-6的分布和mRNA转录量的影响。选择35日龄体重为8.45 kg±0.94 kg的健康三元杂交(杜×长×大)雌性仔猪40头,随机分为2个处理组,每组20头。对照组饲喂基础饲粮,镰刀菌毒素组饲喂含有镰刀菌毒素(玉米赤霉烯酮0.90 mg•kg-1,呕吐毒素1.43 mg•kg-1,烟曲霉毒素5.85 mg•kg-1)的试验饲粮,预试期7 d,正试期35 d,试验结束每组随机选取10头仔猪进行屠宰取样。结果表明:与对照组相比,镰刀菌毒素组仔猪小肠IL-1β和IL-6的阳性细胞呈现由分散在固有层向绒毛内淋巴细胞集中的趋势,而结肠的IL-1β和IL-6阳性细胞主要分布在固有层;十二指肠IL-1β、十二指肠和空肠的IL-6以及结肠IL-1β和IL-6的mRNA转录量显著高于对照组(P<0.05),且小肠和结肠IL-1β和IL-6 mRNA转录量存在一定相关性(P<0.05)。在本试验条件下,镰刀菌毒素可通过改变肠道IL-1β和IL-6的分布和表达,影响肠道的免疫机能。

Abstract:

The aim of the present study was to investigate effects of Fusarium toxins on distribution and mRNA expression levels of intestinal IL-1β and IL-6 in post-weaning piglets.A total of 40 healthy piglets (Duroc×Landrace×Large White) aged at 35 d with an average body weight (8.45±0.94) kg were randomly allocated into two treatments with 20 in the control group (Control) and 20 in the test group (Fusarium Toxins).Piglets in the control group were fed a basal diet only,and piglets in the Fusarium toxins group were fed a test diet (0.90 mg•kg-1 ZEN,1.43 mg•kg-1 DON,5.85 mg•kg-1 FUM).The experimental period was 35 d after 7 d adaptation.Then 10 piglets of each treatment were chosen to slaughter and sample.Results showed because of the Fusarium toxins,the positive cells of the small intestinal IL-1β and IL-6 were from dispersed in the lamina propria to villous lymphocytes concentration.But the IL-1β and IL-6 positive cells of the colon were mainly distributed in the lamina propria cells.And the IL-1β mRNA levels of duodenum,the IL-6 mRNA levels of duodenum and jejunum and the IL-1β and IL-6 mRNA levels of colon of the Fusarium toxins group were significantly higher (P<0.05) than that of the control.The mRNA levels of IL-1β and IL-6 had a correlation between small intestine and colon.In the present study,it suggested that Fusarium toxins exerted a deleterious effect on inflammatory response via distribution and mRNA expression levels of intestinal IL-1β and IL-6,which have a negative impact on immunity of piglets eventually.
