[Role of Enterococcus faecium SF 68 in experimental infection in mice].

The normal intestinal flora is an important defence against various infectious agents. It also allows important metabolic stages in the host. The Authors studied the ability of Enterococcus faecium SF 68 to protect the mice (Swiss strain) from infection by Salmonella typhi and its role when used with penicillin in infection by Staphylococcus aureus. Our results showed that SF 68, determined a good protection against infection. Moreover the association E. faecium SF 68-antibiotic lowers the mortality rate in the infected mice compared with the control group.
