Abstract

genospecies (genomic species) 10 and 11 were described by Bouvet and Grimont in 1986 on the basis of DNA–DNA reassociation studies and comprehensive phenotypic analysis. In the present study, the names sp. nov. and sp. nov., respectively, are proposed for these genomic species based on the congruence of results of polyphasic analysis of 33 strains (16 and 17 strains of genomic species 10 and 11, respectively). All strains were investigated by selective restriction fragment amplification (i.e. AFLP) analysis sequence analysis, amplified rDNA restriction analysis and tDNA intergenic length polymorphism analysis, and their nutritional and physiological properties were determined. Subsets of the strains were studied by 16S rRNA gene sequence analysis and matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) MS or had been classified previously by DNA–DNA reassociation. Results indicate that and represent two phenetically and phylogenetically distinct groups within the genus . Based on the comparative analysis of housekeeping genes (16S rRNA and genes), these species together represent a monophyletic branch within the genus. Despite their overall phenotypic similarity, the ability to oxidize -glucose and to grow at 38 °C can be used in the presumptive differentiation of these two species from each other: with the exception of three strains that were positive for only one test, strains were positive for both tests, whereas strains were negative in these tests. The strains of originated mainly from human clinical specimens, whereas strains were isolated from different environmental sources in addition to human specimens. The type strain of sp. nov. is LMG 1003 (=CIP 70.12 =ATCC 17924) and that of sp. nov. is LMG 988 (=CIP 63.46 =ATCC 11171 =CCUG 2491).
