First isolation of Mycobacterium kyorinense from clinical specimens in Brazil

Abstract

In this article, the first isolation of Mycobacterium kyorinense specimens in Brazil is described. M. kyorinense is a recently identified species, with a few strains reported only in Japan. The Brazilian isolates were initially identified as Mycobacterium celatum by PCR restriction enzyme pattern analysis (PRA) with hsp65. However, biochemical tests indicated the same profile of M. kyorinense and distinguished them from M. celatum and Mycobacterium branderi. The sequencing of the hsp65, rpoB, and 16S rRNA genes allowed the accurate identification of isolates as M. kyorinense.

Phylogenetic tree computed from the concatenation of 16S rRNA gene, rpoB, and hsp65 sequences by the neighbor-joining method and with Kimura's two-parameter model as the substitution model. The significance of branches is indicated by bootstrap values calculated for 1,000 replicates. Nocardia farcinica sequence was used as an outgroup.
