Comparison of the 16S-23S rRNA intergenic spacer regions between Fusobacterium varium and "Fusobacterium pseudonecrophorum" strains.
The 16S-23S rRNA intergenic spacer regions (ISRs) of five strains of "Fusobacterium pseudonecrophorum" which had been proposed as a new species, were compared with those of F. varium ATCC 8501T. All the strains of "F. pseudonecrophorum" exhibited of sequence similarities of 97.7% to 100% to the strain of F. varium in their 16S-23S rRNA ISR sequences. This indicates that the strains of "F. pseud...
متن کاملDifferentiation of two biovars of Ureaplasma urealyticum based on the 16S-23S rRNA intergenic spacer region.
The 16S-23S rRNA intergenic spacer regions of 14 strains representing the 14 serovars of Ureaplasma urealyticum were amplified by PCR and sequenced for genetic differentiation between the two biovars Parvo and T960. Although the spacer region of the Parvo and T960 biovars comprised 302 nucleotides and lacked spacer tRNA genes, 15 nucleotides were different between the two biovars. The four nucl...
متن کاملMechanisms behind variation in the Clostridium difficile 16S–23S rRNA intergenic spacer region
Clostridium difficile infection is an increasing problem in hospitals worldwide, mainly due to the recent emergence of a hypervirulent C. difficile strain. C. difficile PCR ribotyping, based on size variation of the 16S-23S rRNA intergenic spacer region (16S-23S ISR), is widely used in Europe for molecular epidemiological investigation. The mechanism underlying the 16S-23S ISR size variations i...
متن کاملRecombination Drives Evolution of the Clostridium difficile 16S-23S rRNA Intergenic Spacer Region
PCR-ribotyping, a typing method based on size variation in 16S-23S rRNA intergenic spacer region (ISR), has been used widely for molecular epidemiological investigations of C. difficile infections. In the present study, we describe the sequence diversity of ISRs from 43 C. difficile strains, representing different PCR-ribotypes and suggest homologous recombination as a possible mechanism drivin...
متن کاملDifferentiation of group VIII Spiroplasma strains with sequences of the 16S-23S rDNA intergenic spacer region.
Spiroplasma species (Mollicutes: Spiroplasmataceae) are associated with a wide variety of insects, and serology has classified this genus into 34 groups, 3 with subgroups. The 16S rRNA gene has been used for phylogenetic analysis of spiroplasmas, but this approach is uninformative for group VIII because the serologically distinct subgroups generally have similarity coefficients >0.990. Therefor...
