( 1991 ) Polyphasic taxonomic study of the genera Gordona and Tsukamurella including the description of Tsukamurella wratislaviensis sp. nov. PMID : 1930572 Abstract >>
Representatives of the genera Gordona and Tsukamurella together with related actinomycetes were the subject of chemotaxonomic, numerical taxonomic and DNA homology studies. In the numerical analysis the organisms were examined for 116 unit characters and the data sorted using the simple matching, Jaccard and pattern coefficients; clustering was achieved using the unweighted pair group method with arithmetic averages algorithm. The numerical groupings were not affected by the statistics used or by test error, estimated at 1.9%. The numerical taxonomic data supported the integrity of the four validly described species of Gordona but indicated that the genus Tsukamurella might encompass a species in addition to Tsukamurella paurometabola. The putative new strains had chemical, enzymic, nutritional and tolerance properties consistent with their assignment to the genus Tsukamurella and formed a DNA homology group corresponding to the one formed by the Tsukamurella paurometabola strains. It is proposed that the new taxon be assigned to the genus Tsukamurella as Tsukamurella wratislaviensis.

( 2001 ) Tsukamurella strandjordae sp. nov., a proposed new species causing sepsis. PMID : 11283073 DOI : 10.1128/JCM.39.4.1467-1476.2001 PMC : PMC87956 Abstract >>
We have isolated a gram-positive, weakly acid-alcohol-fast, irregular rod-shaped bacterium from cultures of blood from a 5-year-old girl with acute myelogenous leukemia. This isolate was compared with 14 other strains including reference strains of Tsukamurella species by a polyphasic approach based on physiological and biochemical properties, whole-cell short-chain fatty acid and mycolic acid analyses, DNA-DNA hybridization, and sequencing of the 16S rRNA gene. This isolate represents a new taxon within the genus Tsukamurella for which we propose the name Tsukamurella strandjordae sp. nov. Our study also revealed that Tsukamurella paurometabola ATCC 25938 represents a misnamed Tsukamurella inchonensis isolate and confirms that Tsukamurella wratislaviensis belongs to the genus Rhodococcus.

( 2002 ) Transfer of Tsukamurella wratislaviensis Goodfellow et a. 1995 to the genus Rhodococcus as Rhodococcus wratislaviensis comb. nov.. PMID : 12054234 DOI : 10.1099/00207713-52-3-749 Abstract >>
A polyphasic study was undertaken to clarify the taxonomic position of the type strain (N805T) of Tsukamurella wratislaviensis. This organism showed a combination of phenotypic properties, notably chemotaxonomic markers, consistent with its classification in the genus Rhodococcus. Comparative 16S rDNA sequencing studies indicated that strain 805T falls into the Rhodococcus erythropolis subclade, where it forms a monophyletic group with the type strains of Rhodococcus opacus and Rhodococcus percolatus. The close relationship between these strains was underpinned by the results of mycolic acid analyses. However, strain N805T was distinguished from the R. opacus and R. percolatus strains in DNA-DNA pairing experiments and by using a range of phenotypic properties. In light of these studies, it is clear that strain N805T is misclassified in the genus Tsukamurella. It is, therefore, proposed that Tsukamurella wratislaviensis Goodfellow et al. 1995 be transferred to the genus Rhodococcus as Rhodococcus wratislaviensis comb. nov..
