Detection and characterization of a ST6 clone of vanB2-Enterococcus faecalis from three different hospitals in Spain

Abstract: Thirteen vancomycin-resistant and teicoplanin-susceptible Enterococcus faecalis isolates were recovered from unrelated patients in three Spanish hospitals from November 2009 to December 2010. All isolates carried the vanB2 gene, showed indistinguishable or closely-related PFGE patterns and were ascribed to the sequence type ST6 (included into the high-risk clonal-complex CC2). They showed a multiresistance phenotype (erythromycin, tetracycline, ciprofloxacin and high-level-resistance to streptomycin, gentamici… Show more

“…The detection of the vanB2 gene is highly relevant since it is the second time that this gene is found in enterococcal isolates from animals (Torres et al, 2003) and the first time in wild animals. There have been several outbreaks and clinical cases related to vanB2 positive isolates, both E. faecalis and E. faecium, in the last years in Spain (Ló pez et al, 2012;Nebreda et al, 2007). Our two isolates belonged to the lineage ST6, which is included in the hospital adapted clonal complex CC2 (Ló pez et al, 2012).…”
