the corresponding spectra were integrated into the system. During the course of this study, three novel strains, designated strains WS4599, WS4601T and WS4602, were identified as being members of the genus Micrococcus. Strains WS4601T and WS4602 were isolated from the examination room and cloakroom of a single medical practice, respectively, whereas strain
WS4599 was isolated from a pharmaceutical clean room.
