PCR amplification of rRNA intergenic spacer regions as a method for epidemiologic typing of Clostridium difficile.
From January to March 1993, a suspected outbreak of antibiotic-associated diarrhea occurred on a pediatric oncology ward of the Clinical Center Hospital at the National Institutes of Health. Isolates of Clostridium difficile obtained from six patients implicated in this outbreak were typed by both PCR amplification of rRNA intergenic spacer regions (PCR ribotyping) and restriction endonuclease ...
متن کاملUse of highly variable intergenic spacer sequences for multispacer typing of Rickettsia conorii strains.
By use of the nearly perfectly colinear genomes of Rickettsia conorii and Rickettsia prowazekii, we compared the usefulness of three types of sequences for typing of R. conorii isolates: (i) 5 variable coding genes comprising the 16S ribosomal DNA, gltA, ompB, and sca4 (gene D) genes, which are present in both genomes, and the ompA gene, which is degraded in R. prowazekii; (ii) 28 genes degrade...
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 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 کاملComparison 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...
