Epidemiology of Enterococcus faecium isolates sampled from different sources in Romania using MLST technique and eBURST algorithm

Enterococcus faecium is emerging as an important cause of multidrug resistance and hospital acquired infections, special attention being paid to the vancomycin resistant species. Therefore, characterization pathogenic strains/isolates plays role in epidemiology infectious diseases. The enterococcal rate was determined from wastewaters Cluj-Napoca area. As presence E. detected, a number isolates wastewater, birds humans were epidemiologically analyzed according MLST website. Comparisons performed against collection available isolates, with multiple origins, contained database. Out collected 11 identified faecalis (40.74%); 8 casseliflavus (29.62%); 5 (18.50%); 2 gallinarum (7.40%) one isolate durans. Based on data using eBURST algorithm, sampled Romania split three groups: group comprised human hosts wastewater (Cj316, 106/6, Cj197, Cj22, 129/6, Cj117, Cj24, 284/7, 43/7), while second (G9, G10-2, G7, G3-2, G9-1) third (G8, G6, 40/7) originated bird hosts. rest not joined particular group, assuming lack phylogenetic bond between these isolates. obtained suggested existence at least two lines Romania: line that had mainly host prevalence, other animal dominated.
