The complete chromosomal sequence of the type strain Corynebacterium atypicum DSM 44849 comprises 2,311,380 bp. A functional annotation revealed the presence of genes involved in the synthesis and export of mycolic acids and in trehalose corynomycolate biosynthesis, supporting the view that the cell envelope of C. atypicum contains mycolic acids.

The complete genome sequence of the type strain Corynebacterium imitans DSM 44264 comprises 2,565,321 bp with a mean G+C content of 64.26%. The detection of the antibiotic resistance genes erm(X), aphA1-IAB, strA-strB, and cmx is fully consistent with the previously observed multidrug-resistant pattern of C. imitans isolates.
