Protective effect oflactobacillus acidophilusandlactobacillus caseion encephalomyocarditis‐virus‐induced disease in mice

Abstract
Treatment of mice with Lactobacillus acidophilus and Lactobacillus casei enhances their resistance to the encephalomyocarditis virus infection. The protective action of lactobacilli on the course of model viral infection was the strongest in mice to which L. acidophilus and L. casei were given intraperitoneally four days prior to infection. The protective action may be due to a specific action on the immune system.
