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 (Nagai, Makino, Ikegami, Itoh, & Yamada, 2011).
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) (Maeda et al., 2009). Other researchers demonstrated this effect on humans (Arimori et al., 2012). 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 (Oo et al., 2016).
