Abstract

Nocardia species are aerobic, gram-positive, filamentous, partially acid-fast actinomycetes which are found worldwide in soil and decaying organic plant matter. When they infect human beings, they generally enter through the respiratory tract and then disseminate systemically. Rarely has a primary infection occurred as the result of direct inoculation. Isolation of Nocardia from clinical specimens and identification of species are difficult. But, with the introduction of new genetic technologies, reports of novel species of Nocardia have increased. We describe a case of cutaneous nocardiosis caused by Nocardia takedensis in an 87-year-old woman who was diagnosed by bacterial culture and 16S ribosomal RNA sequencing. N. takedensis has been described as a new species. This report describes the first clinical isolate of N. takedensis from a skin specimen in Korea.
