Background: Mexico has the largest number of clinical cases of actinomycetoma in North and South America. Species originally identified by less specific methods have been recently reclassified as other known species or as new species.

Objective: To assess, by 16S rRNA gene sequencing and phenotypic methods, the species distribution of 18 human clinical isolates originally identified as N.

Nocardiosis is a rare disease that is difficult to diagnose. Pulmonary forms are most common in association with a variety of nonspecific symptoms. Up to now isolation of the offending species, i.

A novel actinomycete, strain OFN S31(T), was isolated from a complex biofilm in the Altamira Cave, Spain. A polyphasic study was carried out to clarify the taxonomic position of this strain. Phylogenetic analysis with 16S rRNA gene sequences of representatives of the genera Corynebacterium, Dietzia, Gordonia, Millisia, Mycobacterium, Nocardia, Rhodococcus, Segniliparus, Skermania, Tsukamurella and Williamsia indicated that strain OFN S31(T) formed a distinct taxon in the 16S rRNA gene tree that was more closely associated with the Mycobacterium clade.

A novel actinomycete strain, OFN S17(T), was isolated from a sample collected from Altamira Cave, Cantabria, Spain. This strain was identified by using a polyphasic taxonomic approach. The 16S rRNA, hsp65 and sod gene sequences of the strain were determined and compared with those of representative Nocardia species.
