Parenteral nutrition bags for newborns were found contaminated by a previously undescribed member of the family Enterobacteriaceae. The six isolates studied by rrs gene (encoding 16S rRNA) sequence analysis and multi-locus sequence analysis (MLSA) formed a discrete branch close to the genera Ewingella, Rahnella, Yersinia,Hafnia and Serratia. Phenotypically, the new taxon was distinct from these five genera. The new taxon gave positive results in Voges-Proskauer, Simmons citrate and o-nitrophenyl-β-galactoside hydrolysis tests; fermented d-glucose, d-mannitol, l-rhamnose, melibiose, l-arabinose and d-xylose; hydrolysed aesculin; and did not ferment maltose, trehalose, raffinose, d-sorbitol, sucrose or cellobiose. Tests for motility, gas production, urease, gelatinase and nitrate reduction were also negative. All isolates failed to grow at 37 °C. The DNA G+C content of strain 130333T was 53 mol%. On the basis of data obtained in this study, the six isolates represent a novel species of a new genus in the family Enterobacteriaceae, named Rouxiella chamberiensis gen. nov., sp. nov. The type strain of the type species is 130333T ( = CIP 110714T = DSM 28324T).
