Furthermore, L. reuteri DSM 17938 and ATCC PTA 6475 were shown in a model of rotavirus infection in new-born mice, to increase the early mucosal rotavirus-specific IgA as well as the diversity of the distal gut microbiome, attenuating rotavirus induced enteritis and reducing the duration of diarrhoea by one day. The gene discussed is CD79A; the disease is Rotavirus infection.
