“…Likewise, although the polyphyletic positions of Klebsiella species have been previously noted, this did not lead to taxonomic reappraisals because in most studies K. pneumoniae subsp. pneumoniae was included as the sole representative of the genus Klebsiella (Spro$ er et al, 1999 ;Hauben et al, 1998 ;Kwon et al, 1997). A recent 16S rDNA-based phylogenetic analysis of K. granulomatis incorporated K. pneumoniae subsp.…”

“…While some genera have been investigated in detail, e.g. Yersinia (Ibrahim et al, 1994), Salmonella (Chang et al, 1997 ;Christensen et al, 1998), Serratia (Dauga et al, 1990 ;Harada et al, 1996) and Erwinia (Kwon et al, 1997 ;Hauben et al, 1998), the genus Klebsiella has not been analysed extensively (Carter et al, 1999). The taxonomy of the genus Klebsiella was characterized by a nomenclature reflecting its colourful history.…”

Phylogenetic analyses ofThe phylogenetic relationships of the type strains of 9 Klebsiella species and 20 species from 11 genera of the family Enterobacteriaceae were investigated by performing a comparative analysis of the sequences of the 16S rRNA and rpoB genes. The sequence data were phylogenetically analysed by the neighbourjoining and parsimony methods. The phylogenetic inference of the sequence comparison confirmed that the genus Klebsiella is heterogeneous and composed of species which form three clusters that also included members of other genera, including Enterobacter aerogenes, Erwinia clusters I and II and Tatumella. Cluster I contained the type strains of Klebsiella pneumoniae subsp. pneumoniae, Klebsiella pneumoniae subsp. rhinoscleromatis and Klebsiella pneumoniae subsp. ozaenae. Cluster II contained Klebsiella ornithinolytica, Klebsiella planticola, Klebsiella trevisanii and Klebsiella terrigena, organisms characterized by growth at 10 SC and utilization of L-sorbose as carbon source. Cluster III contained Klebsiella oxytoca. The data from the sequence analyses along with previously reported biochemical and DNA-DNA hybridization data support the division of the genus Klebsiella into two genera and one genogroup. The name Raoultella is proposed as a genus name for species of cluster II and emended definitions of Klebsiella species are proposed.

“…(Samson et al 2005), formerly named Pectobacterium chrysanthemi (Hauben et al 1998) and Erwinia chrysanthemi (Burkholder et al 1953) are the causal agents of stem wet rot and blackleg in potato. These bacteria can also cause soft rot during transit and storage.…”

Sixty-five potato strains of the soft rotcausing plant pathogenic bacterium Dickeya spp., and two strains from hyacinth, were characterised using biochemical assays, REP-PCR genomic finger printing, 16S rDNA and dnaX sequence analysis. These methods were compared with nineteen strains representing six Dickeya species which included the type strains. A group of twenty-two potato strains isolated between 2005-2007 in the Netherlands, Poland, Finland and Israel were characterised as belonging to biovar 3. They were 100% identical in REP-PCR, dnaX and 16S rDNA sequence analysis. In a polyphasic analysis they formed a new clade different from the six Dickeya species previously described, and may therefore constitute a new species. The strains were very similar to a Dutch strain from hyacinth. On the basis of dnaX sequences and biochemical assays, all other potato strains isolated in Europe between 1979 and 1994 were identified as D. dianthicola (biovar 1 and 7), with the exception of two German strains classified as D. dieffenbachia (biovar 2) and D. dadantii (biovar 3), respectively. Potato strains from Peru were classified as D. dadantii, from Australia as D. zeae and from Taiwan as D. chrysanthemi bv. parthenii, indicating that different Dickeya species are found in association with potato.

“…Identification of pectolytic erwinias is traditionally based on biochemical and phenotypic characteristics (De Boer & Kelman, 2000), and more recently molecular techniques have also been applied. As a result, Hauben et al (1998) suggested that the pectolytic bacteria should be placed in a separate genus (Pectobacterium) on the basis of the 16S rDNA sequences. Gardan et al (2003) elevated three subspecies of Pectobacterium carotovorum to species level (P. atrosepticum, P. betavascularum and P. wasabi).…”

“…Gardan et al (2003) elevated three subspecies of Pectobacterium carotovorum to species level (P. atrosepticum, P. betavascularum and P. wasabi). Presently, the taxonomy of Erwinia is in a state of flux (Yap et al, 2004), and the proposed name Pectobacterium by Hauben et al (1998) has not yet been accepted by many researchers working with this group of bacteria.…”

-The objetive of this work was to identify the pectolytic bacteria associated with soft rot of arracacha roots in Brazil. From 1998 to 2001, 227 isolates of Erwinia spp. were obtained from arracacha roots and identified by biochemical and physiological tests (pectolytic activity, lecithinase, α-methyl glucoside, phosphatase, erythromycin sensivity, growth at 37 o C). Of these isolates, 89.9% were identified as E. chrysanthemi (Ech), 9.7% as E. carotovora subsp. carotovora (Ecc) and 0.5% as E. carotovora subsp. atroseptica. The identity of seventeen out of twenty representative isolates of Ech and Ecc was confirmed by PCR (primers '149f', 'L1r', 'ADE1', 'ADE2').
