title: Organisms designated as Nocardia asteroides drug pattern type VI are members of the species Nocardia cyriacigeorgica.
abstract: Nocardia cyriacigeorgica has recently been described as an "emerging" pathogen. However, DNA-DNA hybridization results confirm that Nocardia asteroides drug pattern type VI, which has long been recognized as a common and significant pathogen in the United States, belongs to the species N. cyriacigeorgica.
