RT Journal Article SR Electronic(1) A1 LA FONTAINE, SHARON A1 ROOD, JULIAN I.YR 1990 T1 Evidence that Bacteroides nodosus Belongs in Subgroup Gamma of the Class Proteobacteria, Not in the Genus Bacteroides: Partial Sequence Analysis of a B. nodosus 16S rRNA Gene JF International Journal of Systematic and Evolutionary Microbiology, VO 40 IS 2 SP 154 OP 159 DO https://doi.org/10.1099/00207713-40-2-154 PB Microbiology Society, SN 1466-5034, AB The taxonomic status of the anaerobe Bacteroides nodosus has for some time been uncertain. To resolve this uncertainty, the distal portion of a 16S rRNA gene from this important ovine pathogen was cloned, mapped, and sequenced. A comparison of the sequence with the sequences of 16S rRNA molecules from other bacteria indicated that B. nodosus is more closely related to Escherichia coli and other members of the class Proteobacteria than to Bacteroides fragilis or the bacteroides-flavobacterium-cytophaga phylum. The evidence from the comparison of sequence signatures suggests that B. nodosus is not a member of the genus Bacteroides but that it belongs in subgroup γ of the class Proteobacteria., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-40-2-154
