In this study we report the genetic analysis (plasmids and bftgenes) of clinical Bacteroides strains isolated during 2010-2013 at Targu-Mures. The prevalence of small molecular weight, usuallycryptic, plasmids (2.7, 4.1 and 5.6 kb) showed similar figure to thatin Hungary and the 5.6 kb plasmid type displayed an associationto B. fragilis strains. The prevalence of the enterotoxin-coding bft gene corresponded to that of in other Europid populations.
