A common feature of all members of this family is their osmo- and halotolerance - the ability to grow at high salt concentrations.
The type species of the genus is Nosocomiicoccus ampullae.
A draft full genome sequence of Nosocomiicoccus massiliensis is available in Genbank (accession CAVG000000000).
The bacterial chromosome has an estimated size of about 1.650.00 nt, and a GC-content of 36.5%.
[2] About 1700 proteins are encoded on the chromosome, and about 1000 proteins have close orthologs in the sibling genera Macrococcus, Salinicoccus and Staphylococcus.
