3.1.2. Effects on Virus Titres Reduction
21 days feeding yogurt fermented with Lactobacillus delbrueckii ssp. bulgaricus OLL1073R-1 (1073R-1) significantly decreased influenza virus titres in infected mice 25.
Results of an animal study in mice conducted by Maeda et al. showed thatheat-killed Lactobacillus plantarum L-137 can lower the viral titres of influenza virus A/FM/1/47 (H1N1, a mouse-adapted strain)26. Other researchers demonstrated this effect on humans 27. Contrary, Another probiotic “heat-treated Enterococcus faecalis strain FK-23 ” during 6-36 months administration for 39 adult HCV-positive subjects could reduce alanine aminotransferase (ALT) and aspartate transaminase (AST) with no significant effect on viral load 28.
