title: Faucicola mancuniensis gen. nov., sp. nov., isolated from the human oropharynx.
abstract: An aerobic, Gram-stain-negative, non-motile coccus, designated strain GVCNT2(T), was isolated from the tonsils of a healthy adult female. Cells were oxidase- and catalase-positive, positive for the production of esterase (C4), esterase lipase (C8) and leucine arylamidase, and weakly positive for naphthol-AS-BI-phosphohydrolase and alkaline phosphatase. Cells were also capable of hydrolysing DNA. Growth was observed at 20-37 °C and in the presence of up to 1.5% NaCl. Phylogenetic analysis of near full-length 16S rRNA gene sequences indicated that the strain exhibited closest sequence similarity to Moraxella boevrei ATCC 700022(T) (94.68%) and an uncultured, unspeciated bacterial clone (strain S12-08; 99%). The major fatty acids were C18:1ω9c, C18 : 0, C16:0 and C16:1ω6c/C16:1ω7c. The DNA G+C content of strain GVCNT2(T) was 40.7 mol%. The major respiratory quinone identified was Q-8. Strain GVCNT2(T) exhibited a comparable phenotypic profile to other members of the genus Moraxella but could be distinguished based on its ability to produce acid (weakly) from d-glucose, melibiose, l-arabinose and rhamnose and on its ability to hydrolyse DNA. On the basis of phenotypic and phylogenetic differences from other members of the family Moraxellaceae, strain GVCNT2(T) is considered to represent a novel species of a new genus, for which the name Faucicola mancuniensis gen. nov., sp. nov. is proposed. The type strain of Faucicola mancuniensis is GVCNT2(T) ( =DSM 28411(T) =NCIMB 14946(T)).
