Kocuria massiliensis sp. nov, a new bacterial species isolated from a patient with foot osteomyelitis.

Most of the species from the genus Kocuria are environmental or commensals of mammalian skin and oral bacteria, and had rarely been associated with human infection. However, recent reports showed an increase of the clinical role of these bacteria in human infectious diseases. Most of the cases occurred in hospitals and were device related. They included bacteremia, peritonitis, abscess, endocarditis and ocular infection. We here describe the main characteristics and the draft genome of Kocuria massiliensis sp. nov., strain P3598T (CSURP3598), a new Kocuria species that caused foot osteomyelitis in a 78-year-old woman. The improvement of diagnostic tools for the identification of bacteria in microbiological laboratories, including MALDI-TOF MS and 16S rRNA sequencing, largely contributed to the emergence and to the expansion of the clinical spectrum of infections caused by Kocuria spp. To the best of our knowledge, we report here the first case of osteomyelitis with a bacterial species from the genus Kocuria.
