A soil isolate representing the putatively novel species 'Nocardia uniformi
s' was found to have morphological, staining and chemotaxonomic properties
consistent with its classification in the genus Nocardia. An almost complet
e sequence of the 16S rDNA of the strain was determined following cloning a
nd sequencing of the amplified gene. The sequence was aligned with those av
ailable for nocardiae and phylogenetic trees were inferred using four tree-
making algorithms. The organism was consistently associated with the type s
train of Nocardia otitidiscaviarum albeit with a relatively low bootstrap v
alue recorded for neighbour-joining analysis. The strain was also readily s
eparated from representatives of all validly described Nocardia species usi
ng a set of phenotypic properties. The genotypic and phenotypic data indica
te that the strain should be assigned to the genus Nocardia as a new specie
s. The name proposed for the new species is Nocardia uniformis. The type st
rain is JCM 3224(T).
