          Abstract

          Recently, a taxonomical re-evaluation of the genus Enterobacter , based on multi-locus sequence typing (MLST) analysis, has led to the proposal that the species Enterobacter pulveris , Enterobacter helveticus and Enterobacter turicensis should be reclassified as novel species of the genus Cronobacter . In the present work, new genome-scale analyses, including average nucleotide identity, genome-scale phylogeny and k-mer analysis, coupled with previously reported DNA–DNA hybridization values and biochemical characterization strongly indicate that these three species of the genus Enterobacter are not members of the genus Cronobacter , nor do they belong to the re-evaluated genus Enterobacter . Furthermore, data from this polyphasic study indicated that all three species constitute two new genera. We propose reclassifying Enterobacter pulveris and Enterobacter helveticus in the genus Franconibacter gen. nov. as Franconibacter pulveris comb. nov. (type strain 601/05 T = LMG 24057 T = DSM 19144 T) and Franconibacter helveticus comb. nov. (type strain 513/05 T = LMG 23732 T = DSM 18396 T), respectively, and Enterobacter turicensis in the genus Siccibacter gen. nov. as Siccibacter turicensis comb. nov. (type strain 508/05 T = LMG 23730 T = DSM 18397 T).

          Genetic features of blaNDM-1-positive Enterobacteriaceae.

          Sandrine Bernabeu, Laurent Dortet, Patrice Nordmann … (2011)
          Genetic features associated with the bla(NDM-1) gene were investigated in 6 Escherichia coli, 7 Klebsiella pneumoniae, 1 Citrobacter freundii, 1 Proteus mirabilis, and 1 Providencia stuartii isolate of worldwide origin. Clonal diversity was observed for both E. coli and K. pneumoniae. The bla(NDM-1) gene was carried by different plasmid types (IncA/C, IncF, IncL/M, or untypeable) and was likely chromosome borne in two isolates. The bla(NDM-1) plasmids coharbored a variety of resistance determinants, including β-lactamase genes, quinolone resistance genes, and 16S RNA methylase genes.

            Cronobacter gen. nov., a new genus to accommodate the biogroups of Enterobacter sakazakii, and proposal of Cronobacter sakazakii gen. nov., comb. nov., Cronobacter malonaticus sp. nov., Cronobacter turicensis sp. nov., Cronobacter muytjensii sp. nov., Cronobacter dublinensis sp. nov., Cronobacter genomospecies 1, and of three subspecies, Cronobacter dublinensis subsp. dublinensis subsp. nov., Cronobacter dublinensis subsp. lausannensis subsp. nov. and Cronobacter dublinensis subsp. lactaridi subsp. nov.

            Roger Stephan, Niall Mullane, Ben Tall … (2008)
            [Enterobacter] sakazakii is an opportunistic pathogen that can cause infections in neonates. This study further clarifies the taxonomy of isolates described as [E.] sakazakii and completes the formal description of the proposed reclassification of these organisms as novel species and subspecies within a proposed novel genus, Cronobacter gen. nov. [E.] sakazakii was first defined in 1980, however recent polyphasic taxonomic analysis has determined that this group of organisms consists of several genomospecies. In this study, the phenotypic descriptions of the proposed novel species are expanded using Biotype 100 and Biolog Phenotype MicroArray data. Further DNA-DNA hybridization experiments showed that malonate-positive strains within the [E.] sakazakii genomospecies represent a distinct species, not a subspecies. DNA-DNA hybridizations also determined that phenotypically different strains within the proposed species, Cronobacter dublinensis sp. nov., belong to the same species and can be considered as novel subspecies. Based on these analyses, the following alternative classifications are proposed: Cronobacter sakazakii gen. nov., comb. nov. [type strain ATCC 29544(T) (=NCTC 11467(T))]; Cronobacter malonaticus sp. nov. [type strain CDC 1058-77(T) (=LMG 23826(T)=DSM 18702(T))]; Cronobacter turicensis sp. nov. [type strain z3032(T) (=LMG 23827(T)=DSM 18703(T))]; Cronobacter muytjensii sp. nov. [type strain ATCC 51329(T) (=CIP 103581(T))]; Cronobacter dublinensis sp. nov. [type strain DES187(T) (=LMG 23823(T)=DSM 18705(T))]; Cronobacter dublinensis subsp. dublinensis subsp. nov. [type strain DES187(T) (=LMG 23823(T)=DSM 18705(T))]; Cronobacter dublinensis subsp. lausannensis subsp. nov. [type strain E515(T) (=LMG 23824=DSM 18706(T))], and Cronobacter dublinensis subsp. lactaridi subsp. nov. [type strain E464(T) (=LMG 23825(T)=DSM 18707(T))].

              Cronobacter condimenti sp. nov., isolated from spiced meat, and Cronobacter universalis sp. nov., a species designation for Cronobacter sp. genomospecies 1, recovered from a leg infection, water and food ingredients.

              Susan Joseph, E Cetinkaya, Stephen Forsythe … (2012)
              A re-evaluation of the taxonomic position of five strains, one assigned to Cronobacter sakazakii (strain 1330(T), isolated from spiced meat purchased in Slovakia), two previously assigned to Cronobacter genomospecies 1 (strains NCTC 9529(T) and 731, isolated from water and a leg infection, respectively) and two previously assigned to Cronobacter turicensis (strains 96 and 1435, isolated from onion powder and rye flour, respectively) was carried out. The analysis included phenotypic characterization, 16S rRNA gene sequencing and multilocus sequence analysis (MLSA) of seven housekeeping genes (atpD, fusA, glnS, gltB, gyrB, infB, ppsA; 3036 bp). 16S rRNA gene sequence analysis and MLSA showed that strain 1330(T) formed an independent phylogenetic lineage in the MLSA, with Cronobacter dublinensis LMG 23823(T) as the closest neighbour. DNA-DNA reassociation and phenotypic analysis revealed that strain 1330(T) represented a novel species, for which the name Cronobacter condimenti sp. nov. is proposed (type strain 1330(T) = CECT 7863(T) = LMG 26250(T)). Strains NCTC 9529(T), 731, 96 and 1435 clustered together within an independent phylogenetic lineage, with C. turicensis LMG 23827(T) as the closest neighbour in the MLSA. DNA-DNA reassociation and phenotypic analysis confirmed that these strains represent a novel species, for which the name Cronobacter universalis sp. nov. is proposed (type strain NCTC 9529(T) = CECT 7864(T) = LMG 26249(T)).
