Chemotaxonomic and 16S rRNA gene sequence analyses of four bacterial strains isolated from clinical material clearly demonstrated that these bacteria belong to the genus Nocardia. DNA--DNA hybridization data as well as the physiological characteristics of the isolates indicated that they are closely related and belong to a single species that differs from previously described members of the genus. The name Nocardia abscessus sp. nov. is proposed for these organisms represented by strain IMMIB D-1592(T) (=DSM 44432(T)). Strain IMMIB D-1592(T) exhibits 56.8 and 60.0% DNA--DNA relatedness to Nocardia asteroides ATCC 19247(T) and Nocardia paucivorans DSM 44386(T), respectively.
