Chemotaxonomic and 16S ribosomal DNA sequence analyses of an isolate f
rom the sputum of a patient with a mycobacterial lung infection clearl
y delineated a new species of the genus Tsukamurella. This new species
can be defined on the basis of genotypic and phenotypic data. The nam
e Tsukamurella pulmonis sp. nov. is proposed for this organism; the ty
pe strain is IMMIB D-1321T (= DSM 44142(T)). This isolate shows 44.2 a
nd 36.2% DNA relatedness to Tsukamurella paurometabola DSM 20162(T) (T
= type strain) and Tsukamurella inchonensis DSM 14067(T), respectivel
y.
