16S ribosomal DNA amplification for phylogenetic study.
A set of oligonucleotide primers capable of initiating enzymatic amplification (polymerase chain reaction) on a phylogenetically and taxonomically wide range of bacteria is described along withExpand

A phylogenetic analysis of the mycoplasmas: basis for their classification.
Small-subunit rRNA sequences were determined for almost 50 species of mycoplasmas and their walled relatives, providing the basis for a phylogenetic systematic analysis of these organisms. FiveExpand

The phylogeny of purple bacteria: the alpha subdivision.
The technique of oligonucleotide cataloging shows the purple photosynthetic eubacteria to comprise three major subdivisions, temporarily called alpha, beta, and gamma--previously designated groupsExpand

Evolutionary relationships within the fungi: analyses of nuclear small subunit rRNA sequences.
Nucleotide sequences of the small subunit ribosomal RNA (18S) gene were used to investigate evolutionary relationships within the Fungi. The inferred tree topologies are in general agreement withExpand

Phylogenetic diversity of the Rickettsiae.
Small subunit rRNA sequences have been determined for representative strains of six species of the family Rickettsiaceae: Rickettsia rickettsii, Rickettsia prowazekii, Rickettsia typhi, CoxiellaExpand

Phylogenetic analysis of the spirochetes.
The 16S rRNA sequences were determined for species of Spirochaeta, Treponema, Borrelia, Leptospira, Leptonema, and Serpula, using a modified Sanger method of direct RNA sequencing. Analysis ofExpand

Evolutionary relationships among pathogenic Candida species and relatives.
Small subunit rRNA sequences have been determined for 10 of the most clinically important pathogenic species of the yeast genus Candida (including Torulopsis [Candida] glabrata and Yarrowia [Candida]Expand

Eubacterial origin of chlamydiae.
The sequence of the 16S rRNA gene from Chlamydia psittaci was determined. Comparison of this sequence with other 16S rRNA sequences showed the organism to be eubacterial. The organism represents aExpand

The Deinococcus-Thermus phylum and the effect of rRNA composition on phylogenetic tree construction.
Through comparative analysis of 16S ribosomal RNA sequences, it can be shown that two seemingly dissimilar types of eubacteria Deinococcus and the ubiquitous hot spring organism Thermus are distantlyExpand

Halobacteroides halobius gen. nov., sp. nov., a Moderately Halophic Anaerobic Bacterium from the Bottom Sediments of the Dead Sea
Summary An anaerobic, long rod-shaped, motile, Gram-negative, non-sporulating bacterium wasisolated from Dead Sea sediment. It required NaCl concentrations between 1.4 and 2.8 mol/l, and optimalExpand
