In the original article, there was an error. Based on the branching position of Mycobacterium vulneris ( van Ingen et al., 2009 ) in different phylogenomic trees and on multiple identified molecular signatures that this species shared with a clade of rapid growing mycobacteria, we proposed a reclassification of M. vulneris , into a new genus, Mycolicibacterium , corresponding to a clade of rapid-growing mycobacteria. However, it was noted in our article that the branching of M. vulneris , which is a slow-growing species with rapid-growing mycobacteria, was anomalous.

In a Frontiers commentary, Tortoli (2018) indicated that the genome sequence of M. vulneris , originally available in the NCBI genome database (accession CCBG00000000; Croce et al., 2014 ), was mislabeled and very likely corresponded to Mycobacterium porcinum (a rapid grower). Tortoli (2018) also reported the sequencing of the type strain of M. vulneris , DSM 45247 T and this genome sequence (accession NCXM01000000) showed the branching of M. vulneris within the slow-growing group of mycobacteria, belonging to the genus Mycobacterium .

Our own analysis with this new genome sequence also confirms the branching of M. vulneris within the delimited genus Mycobacterium , encompassing different slow-growing mycobacteria. As a result, the transfer of M. vulneris into the genus Mycolicibacterium as proposed in Table 11 of our article was incorrect as a direct result of the mislabeling of the available genome sequence for this species. To correct this error, we propose that the species Mycolicibacterium vulneris ( Gupta et al., 2018 ) should be reinstated to its previous basonym Mycobacterium vulneris ( van Ingen et al., 2009 ) and as part of the genus Mycobacterium ( Gupta et al., 2018 ).

The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way.
