Ability of Lactobacillus casei and Lactobacillus reuteri to protect against oxidative stress in rats fed aflatoxins-contaminated diet

► The role of Lactobacillus casei and L. reuteri was studied in aflatoxin-treated rats. ► Serum biochemical parameters, antioxidant and oxidative stress markers were studied. ► Histological examination of liver tissues was also carried out. ► Both strains showed a protective effect and L. reuteri was effective than L. casei. ► These strains might be incorporate into food to protect against aflatoxin.
