D. hansenii strains inter-LTR fingerprinting. Origin and biotope of isolation of the 56 studied D. hansenii strains is indicated. Stars indicate strains displaying a unique profile. Strains with similar profiles are boxed. The vertical bar indicates the 75% similarity cut-off. Note that, although the strains CLIB 239 and CLIB 677 display similarity below the 75% threshold, they were not grouped in a cluster as their respective profiles are clearly different. N/A: not available.
