Abstract
Staphylococcus hyicus demonstrated characteristic bacteriolytic activities towards a Micrococcus luteus reference strain. This lytic activity was demonstrated on medium containing M. luteus cells as large zones of transparency around the culture streak. Smaller zones of transparency were observed with Staphylococcus intermedius, Staphylococcus chromogenes, and some strains of Staphylococcus aureus but not with other coagulase-negative staphylococcal species. The distribution and extent of the bacteriolytic activity could be useful as additional criteria for differentiation of S. hyicus.
