[Action of egg lysozyme on representatives of the family Micrococcaceae. The action on staphylococci].

The results of the study on the effect of various concentrations of lysozyme on staphylococci of three species, i.e. Staphylococcus aureus, Staphylococcus epidermidis and Staphylococcus saprophyticus are presented. The study was performed with the use of the turbidimetric method. It was found that all the staphylococci had a common tendency for changing the optic density (OD) of the suspensions under the effect of lysozyme which was different from that in Micrococcus luteus. However, the dynamics of decreasing the OD in Staph. saprophyticus was characterized by some properties which provided a supposition that the structures of the cell walls in Staph. aureus and Staph. epidermidis were close, while the cell walls in Staph. saprophyticus had some unknown characteristics.
