Nocardiae are relatively inactive in standard biochemical tests, and speciation with traditional biochemical methods is difficult. Since the year 2000, molecular phylogenetic techniques, primarily based on 16S rRNA gene sequences, have identified more than 100 Nocardia species, many of which are implicated in human disease.
