摘要

本试验旨在研究黄曲霉毒素M1(AFM1)与赭曲霉毒素A(OTA)对小鼠肠道内微生物菌群结构的影响。试验选用健康的48只4周龄ICR小鼠,随机分成4组,每组12只,对照组灌胃1%二甲基亚砜(DMSO)溶液,AFM1组灌胃3.5 mg/kg BW AFM1,OTA组灌胃3.5 mg/kg BW OTA,AFM1+OTA组灌胃3.5 mg/kg BW AFM1+3.5 mg/kg BW OTA,每天灌胃1次,连续灌胃35 d。灌胃结束后,采用16S rRNA测序对小鼠结肠微生物多样性进行分析。结果表明:与对照组相比,AFM1与OTA处理后,不论单独或者混合处理都会导致厚壁菌门、乳杆菌科、乳酸菌属、益生菌拟普雷沃菌属相对丰度显著降低(P<0.05);拟杆菌门、变形菌门、瘤胃球菌科、肠杆菌科、梭菌属相对丰度显著增加(P<0.05)。综合试验结果表明,AFM1、OTA单独及联合处理均改变了小鼠肠道内微生物菌群结构,损伤了肠道微生物屏障功能。

Abstract

This study was aimed to investigate the effects of aflatoxin M1 (AFM1) and ochratoxin A (OTA) on the structure of intestinal microflora of mice. A total of 48 healthy 4-week-old ICR mice were selected and randomly divided into 4 groups with 12 mice in each group. The control group was gavaged with 1% dimethyl sulfoxide (DMSO) solution, the AFM1 group was gavaged with 3.5 mg/kg BW AFM1, OTA group was gavaged with 3.5 mg/kg BW OTA, and the AFM1+OTA group was gavaged with 3.5 mg/kg BW AFM1+3.5 mg/kg BW once a day for 35 days. After intragastric administration, microbial diversity in the colon of mice was analyzed by 16S rRNA sequencing. The results showed that after AFM1 and OTA treatment, compared with control group, both single and mixed treatments resulted in decreased relative abundance of Firmicutes, Lactobacillaceae, Lactobacillus and Alloprevotella (P<0.05), and increased relative abundance of Bacteroidetes and Proteobacteria, Ruminococcaceae and Enterobacteriaceae, Clostridium_Sensu_Stricto_1 (P<0.05). These results indicate that both AFM1 and OTA treatments change the structure of intestinal microflora and impair the function of intestinal microbial barrier in mice.
