*
> signs denote estimations by Southern blot with the respective XXR-specific probes.
†
Number of cassettes sequenced.
‡
Two distinct subgroups with at least 60% identity between them were present in the total number of cassettes examined. The percent similarity is among XXR within the respective subgroups.
§
Partial sequence of intI gene.
