sp. nov., isolated from a hospital floor swab.

During the analysis of a collection of strains linked to an outbreak in an intensive care unit at King Faisal Specialist Hospital and Research Center in 2019, one isolate (CFS3442) was identified phenotypically as . However, whole-genome sequencing revealed its true identity as a member of the genus , distinct from both and . The isolate demonstrated: (i) a significant phylogenetic distance from ; (ii) considerable genomic differences from several reference strains and other species; and (iii) unique phenotypic characteristics. Based on the combined geno- and phenotypic data, we propose that this isolate represents a novel species within the genus , for which the name sp. nov. is proposed. The type strain is CFS3442 (=NCTC 14921=LMG 33162).
