“…Several attempts have been made to clarify the taxonomic structure of Erwinia; these have been based on different methodologies, such as deoxyribonucleic acid (DNA)-DNA hybridization (2, &lo, 29,32,47), comparative phenotypic studies (17,(21)(22)(23)(24)(25)27,30,45,67), serological studies (11,19,59,60,72), gel electrophoresis of proteins (43,44,46,69), and characterization of the respiratory quinones and enzymes of fumarate metabolism (32). The problems related to the taxonomy of Erwinia have been discussed extensively (5 , 41, 45, 63, 65).…”

API 20E and API SOCHE systems (72 phenotypic tests) were applied to a total of 529 strains, including 421 strains belonging to 21 different Erwinia species, 66 Enterobacter agglomerans strains, 18 Escherichia adecarboxylata strains, and 24 strains of 16 other enterobacteria. The results were analyzed numerically by using the Gower similarity coefficient and the unweighted average linkage method. The named Erwinia strains were distributed over 27 phena, some of which also contained strains received as Enterobacter agglomerans. Strains of Erwinia amylovora, Erwinia chrysanthemi, Erwinia cypripedii, Erwinia mallotivora, Erwinia nigrijiuens, Erwinia paradisiaca, Erwinia quercina, Erwinia rubrifaciens, Erwinia salicis, Erwinia stewartii, and Escherichia adecarboxylata constitute separate phena. Erwinia carotovora, Erwinia chrysanthemi, and Erwinia rhapontici are heterogeneous, but distinct from each other and from the other phena. The type strains of Erwinia herbicola, Enterobacter agglomerans, and Erwinia milletiae fall into one phenon, and strains of Erwinia ananas and Erwinia uredovora are in a single phenon. Obviously misnamed Erwinia herbicola and Enterobacter agglomerans strains can be assigned to other species, such as Erwinia cypripedii, Erwinia ananas, Erwinia rhapontici, Rahnella aquatilis, Enterobacter sakazakii, Escherichia adecarboxyluta, and Serratia marcescens or to as-yet-unnamed phena. Three Erwinia carnegieana strains, but not the type strain, form one phenon. Erwinia dissolvens and Erwinia nimipressuralis should be allocated to Enterobacter. Our results confirm the heterogeneous taxonomic structure of the genus Erwinia.According to Lelliott and Dickey (41), the genus Erwinia consists of 15 species that are associated with plants as pathogens, saprophytes, or epiphytes. Erwinia herbicola also includes human clinical isolates. There are 21 Erwinia species names on the Approved Lists of Bacterial Names (58).Several attempts have been made to clarify the taxonomic structure of Erwinia; these have been based on different methodologies, such as deoxyribonucleic acid (DNA)-DNA hybridization (2, &lo, 29,32,47), comparative phenotypic studies (17,(21)(22)(23)(24)(25)27,30,45,67), serological studies (11,19,59,60,72), gel electrophoresis of proteins (43,44,46,69), and characterization of the respiratory quinones and enzymes of fumarate metabolism (32). The problems related to the taxonomy of Erwinia have been discussed extensively (5 , 41, 45, 63, 65). These problems are based mainly on the heterogeneity of the genus Erwinia, as reflected in (i) the (former) subdivision of Erwinia into three "natural groups" based on phytopathological characteristics (21-25, 40), (ii) the unclear delineation of some species, such as Erwinia carotovora and Erwinia herbicola, due to their internal heterogeneity (4, 45, 63, 65), and (iii) the existence of an "Erwinia herbicola-Enterobacter agglomerans complex," with unclear relationships among its members and with other taxa of the Enterobacteriaceae (4).Because of the inadequa...

“…atrosepticum, denominada P. carotovorum subsp. betavasculorum (Thomson et al, 1981), e com conteúdo de G+C intermediária entre P. carotovorum subsp. carotovorum e P. chrysanthemi, é uma indicação de que as formas intermediárias possuem uma importância epidemiológica significativa e podem ser encontradas com maior freqüência a medida que levantamentos mais amplos sejam efetuados.…”

Tubérculos de batata (Solanum tuberosum)-semente, pré-básica, básica, registrada e certificada, de oito cultivares, oriundos de 21 lavouras localizadas nos municípios de Vacaria, Canguçu, Piratini e Ibiraiaras, no Rio Grande do Sul, foram coletados nos meses de maio a agosto de 2002. Cada tubérculo foi lavado em água corrente, deixado secar à temperatura ambiente, perfurado com palitos em dez lenticelas, coberto com fina camada de óleo de soja, colocado individualmente em cima de folha de papel toalha umedecida dentro de saco plástico transparente e incubado a 23 ºC por quatro dias. A incidência de podridão mole a partir das lenticelas variou de 20_100% entre as cultivares. Pectobacterium sp. foi constatada em tubérculos das 21 lavouras. Duzentos e vinte e três isolados de Pectobacterium sp. foram obtidos em meio CPG, a partir das lenticelas com podridão mole, e identificados por testes bioquímicos, fisiológicos e PCR em nível de subespécie. Cento e dezenove isolados foram identificados como P. carotovorum subsp. brasiliensis e e 96 com o P. carotovorum subsp. carotovorum. Oito isolados não se enquadraram na classificação bioquímica. Pectobacterium carotovorum subspp. estavam presentes em tubérculos de batata-semente, independente da cultivar, classe ou município de origem. Pectobacterium carotovorum subsp. atrosepticum, a principal responsável por causar canela preta em batata em outros países, não foi detectada.

“…They belonged to one of three species, namely Erwinia cacticida, Erwinia carotovora and Erwinia chrysanthemi (Young et al 1996). Erwinia carotovora was further classified into the subspecies atroseptica (Lelliott & Dickey 1984), betavasculorum (Thomson et al 1981), odorifera (Gallois et al 1992) and wasabiae (Goto & Matsumoto 1987) according to pathogenecity and host-plant specificity. The genus Erwinia was subsequently divided into three phylogenic groups, and members of clade II, including the five Erwinia carotovora subspecies, E. cacticida, E. chrysanthemi and E. cypripedii, were united in the genus Pectobacterium (Hauben et al 1998), which was first described by Waldee (1945).…”
