Lytic patterns of Staphylococcus epidermidis type 1.

In typing of Staphylococcus epidermidis higher concentrations of phages should be used in view of the danger of committing an error while typing at RTD only. Lytic patterns may be divided into long and short ones. The latter possess greater identification value. There are several phage types of Staphylococcus epidermidis type 1 which are more common. Phage type A 9c is chiefly encountered in hospital environments.
