TL;DR: The 16S rRNA gene sequences were determined by PCR direct sequencing and were compared with more than 80 previously determined clostridial sequences and the previously published sequences of representative species of other low- G + C-content gram-positive genera, thereby providing an almost complete picture of the genealogical interrelationships of theClostridia.

TL;DR: The majority of generated rDNA sequences did not correspond to known organisms and clearly derived from hitherto unknown species within this human gut microflora, including Clostridium coccoides and Eubacterium rectale.

TL;DR: Significant alterations in the upper and lower intestinal flora of children with late-onset autism are demonstrated and may provide insights into the nature of this disorder.

TL;DR: The small-subunit rRNA sequences of 51 species of Bacillus were determined by reverse transcription to elucidate the phylogenetic structure of the genus Bacillus and revealed five phylogenetically distinct clusters as mentioned in this paper.

TL;DR: The primary structures of the 16S rRNAs of Bacillus anthracis, Bacillus cereus, Bacillin mycoides, and Bacillus thuringiensis were determined by using the reverse transcription-dideoxy sequencing method, and all of the strains exhibited very high levels of sequence similarity that were consistent with the close relationships shown by previous DNA hybridization studies.
