Genetic relationship of multiple-locus variable-number tandem repeat analysis (MLVA) patterns of the 89 methicillin-resistant Staphylococcus epidermidis isolates collected during the 2006 (▵) and 2008 (▴) sampling campaigns, as implemented by the BioNumerics version 6.0 software (Applied Maths NV, Sint-Martens-Latem, Belgium) by using the unweighted pair group method with arithmetic mean (UPGMA). The symbols §, ‡, and # indicate MLVA genotypes that were found only in 2006, only in 2008, or both, respectively. Staphylococcal cassette chromosome mec elements (SCCmec) are defined by the ccr-mec allotype combination according to the current classification used in methicillin-resistant S. aureus (21). MLVA patterns are defined as the number of tandem repeats for each of the five Se loci (Se1, Se2, Se3, Se4, Se5) (23). ccr allotypes are classified as types 1 to 4 (i.e., ccrA1B1 to ccrA4B4) and 5 (i.e., ccrC). ND, nondetectable ccr gene complex; NT, nontypeable mec allotypes or SCCmec.
