A Medium for Isolation and Tentative Identification of Fecal Streptococci, and Their Role as Avian Pathogens

A selective differential medium is described which is useful in primary isolation and identification of Streptococcus fecalis, S. faecium, S. durans, and other bacteria, notably Staphylococcus aureus. In laboratory studies, S. fecalis strains were found to be much more pathogenic than strains of S. durans and S. faecium. Methods of isolation and the importance of enterococci as primary pathogens are discussed.
