Gram-negative bacteria were isolated from knots induced by Pseudomonas savastanoi in olive trees (Olea europaea L.). A total of nine endophytic bacterial strains were isolated, each from inside a different tree knot. Biochemical characterization indicated that all the strains belong to the family Enterobacteriaceae. Phylogenetic analyses of the 16S rRNA genes of these novel isolates revealed that they formed a homogeneous cluster within Erwinia species. DNA signatures of these isolates were identical to those described for the genus Erwinia. The strains formed a homogeneous group as shown by DNA-DNA hybridization analysis and numerical analysis of phenotypic data, clearly differentiated from all species of Erwinia with validly published names. The data provide strong evidence of the differentiation of these strains from the most closely related species. Therefore, these isolates represent a novel species, for which the name Erwinia toletana sp. nov. is proposed. The isolates are available at CFBP, CECT and ATCC. The G+C content is 52±0?5 mol%. The type strain is CFBP 6631 T (=A37 T =ATCC 700880 T =CECT 5263 T ). Ewing & Fife (1971, 1972 concluded that strains isolated from clinical sources and strains belonging to the Herbicola group of Dye (1969) are the same species and referred to them as the 'Enterobacter agglomerans-Erwinia herbicola' complex. Lelliott & Dickey (1984) defined Erwinia as associated with plants as pathogens, saprophytes or constituents of the epiphytic flora. They considered Erwinia herbicola as yellow and non-pigmented Erwinia-like organisms that exist either on plant surfaces or as secondary organisms in lesions caused by many plant pathogens, as described by Billing & Baker (1963). Gavini et al. (1989) described the new genus Pantoea and the species Pantoea agglomerans, which includes the type strains of Enterobacter agglomerans, Erwinia herbicola and Erwinia milletiae. Later, Erwinia ananatis (synonym Erwinia uredovora) and Erwinia stewartii were transferred to the genus Pantoea (Mergaert et al., 1993). Based on 16S rRNA gene phylogenetic analyses, plant-associated bacteria were reclassified into four genera: Erwinia, Pectobacterium, Brenneria and Pantoea (Hauben et al., 1998). Mergaert et al. (1999) reclassified nonpigmented Erwinia herbicola epiphytic strains isolated from trees as Erwinia billingiae, which clades within the first cluster of Hauben et al. (1998).Samples from diseased olive trees were collected from the Navahermosa and Chozas areas in the Toledo region of central Spain. Strains from knots were isolated according to the method of García de los Ríos (1999) and were grown on King's medium B (KB) and nutrient agar for 48 h at 25 uC. Two colony types were easily distinguishable on both agar media. Pure cultures were established by single colony isolation onto fresh KB agar. The first type was identified as Pseudomonas savastanoi. The second type, which corresponded to large (3-5 mm), mucilaginous, pigmented and non-pigmented colonies, was identified as a member of 3Present a...

“…Since the early 1970s, various attempts have been made to clarify the Erwinia herbicola-Enterobacter agglomerans complex (Ewing & Fife, 1972;Gardner & Kado, 1972;Young et al, 1978;Dye, 1981;Brenner et al, 1984;Verdonck et al, 1987;Beji et al, 1988). The most comprehensive study to date was performed by Brenner et al (1984), who separated 124 strains belonging to this complex into 13 groups based on their DNA-DNA hybridization relatedness.…”

Bacterial strains belonging to DNA hybridization groups (HG) II, IV and V, in the Erwinia herbicola-Enterobacter agglomerans complex, of Brenner et al. [Int J Syst Bacteriol 34 (1984), [45][46][47][48][49][50][51][52][53][54][55] were suggested previously to belong to the genus Pantoea, but have never been formally described and classified. Additionally, it has been shown in several studies that Pectobacterium cypripedii is more closely related to species of Pantoea than to those of Pectobacterium. In this study, the phylogenetic positions of Brenner's DNA HG II, IV and V and Pectobacterium cypripedii were re-examined by both 16S rRNA gene sequencing and multilocus sequence analyses (MLSA) based on the gyrB, rpoB, atpD and infB genes. The analyses revealed that DNA HG II, IV and V and Pectobacterium cypripedii form five separate branches within the genus Pantoea (strains from HG V were split into two branches). DNA-DNA hybridization data further confirmed that DNA HG II, IV and V constitute four separate species. Pectobacterium cypripedii was shown to be a close phylogenetic relative of Pantoea dispersa and DNA HG IV by both 16S rRNA gene sequence and MLSA analyses. Biochemical analyses performed on strains from DNA HG II, IV and V and Pectobacterium cypripedii confirmed their taxonomic position within the genus Pantoea and revealed phenotypic characteristics that allow the differentiation of these species from each other and from their closest phylogenetic neighbours. It is proposed to emend the description of the genus Pantoea and to describe Pantoea septica sp. nov. for DNA HG II (type strain LMG 5345 T 5BD 874 T 5CDC 3123-70 T ), Pantoea eucrina sp. nov. for DNA HG IV (type strain LMG 2781 T 5BD 872 T 5CDC 1741-71 T 5LMG 5346 T ), Pantoea brenneri sp. nov. for strains of DNA HG V excluding LMG 24534 (type strain LMG 5343 T 5BD 873 T 5CDC 3482-71 T ) and Pantoea conspicua sp. nov. for the remaining strain of DNA HG V (type strain LMG 24534 T 5BD 805 T 5CDC 3527-71 T ) and to transfer Pectobacterium cypripedii to the genus as Pantoea cypripedii comb. nov. (type strain LMG 2657 T 5ATCC 29267 T 5DSM 3873 T 5LMG 2655 T ).Abbreviations: HG, hybridization group; MLSA, multilocus sequence analysis.

“…Ewing and Fife (10) reported that 80% of strains belonging to the species Enterobacter agglomerans are anaerogenic, while the remaining strains are aerogenic. Biochemical studies carried out on these organisms have shown that the aerogenic strains resemble Enterobacter cloacae and other Enterobacter species more closely than they resemble anaerogenic strains (10,20). On the other hand, some biochemical characteristics of the anaerogenic strains (such as yellow pigmentation) resemble those typically associated with Erwinia species (19, 20).…”

“…These authors further classified the strains belonging to Enterobacter agglomerans into seven anaerogenic biogroups and four aerogenic biogroups. The majority of strains are anaerogenic (10,20). When the biochemical characteristics of the aerogenic and anaerogenic strains of Enterobacter agglomerans were compared with the characteristics of strains of Enterobacter cloacae, it was found that the strains belonging to the aerogenic biogroups are more similar to the Enterobacter cloacae strains than the strains belonging to the anaerogenic biogroups are (10,20).…”

showed that the type strains of Enterobacter agglomerans (ATCC 27155) and Envinia herbicola (ATCC 33243) belong to the same genomic species. We suggest that Enterobacter agglomerans (= Erwinia herbicola) should be excluded from the genus Enterobucter. We further suggest that strains currently designated Enterobacter agglomerans can be grouped with Erwinia herbicola or with the enteric cluster containing Enterobacter depending upon whether bifunctional AS:PRT is absent or present, respectively.
