Facklamia languida sp. nov., isolated from human clinical specimens

Three strains of a gram-positive catalase-negative, facultatively anaerobic coccus-shaped organism originating from human clinical samples were charac terized by phenotypic and molecular taxonomic methods. Sequencing of genes encoding 16S rRNA showed that the strains are phylogenetically closely rela ted (99.9 to 100% sequence similarity) and represent a new subline within t he genus Facklamia. The unknown bacterium was readily distinguished from al l currently described species of the genus Facklamia (viz., Facklamia homin is, Facklamia ignava, and Facklamia sourekii) by biochemical tests and elec trophoretic analysis of whole-cell proteins. Based on phylogenetic and phen otypic evidence, it is proposed that the unknown bacterium be classified as Facklamia languida sp. nov. The type strain off. languida is CCUG 37842.
