Using core genome multilocus sequence typing (cgMLST) for vancomycin-resistant Enterococcus faecium isolates to guide infection control interventions and end an outbreak.

Objectives: Until July 2016, vancomycin-resistantEnterococcus faecium (VREfm) was sporadically detected in Odense University Hospital, Denmark. After July 2016, the number of VREfm cases increased. This study aimed to apply a core genome multilocus sequence typing (cgMLST) scheme for E.

[Epidemic increase in the incidence of carbapenemase-producing Enterobacteriaceae in Denmark].

Carbapenemase-producing Enterobacteriaceae (CPE) are extremely multiresistant bacteria with few or no treatment options. Infections with CPE are associated with a mortality of 40-50%. In Denmark, CPE were first detected in 2008.

Fatal Septicemia Linked to Transmission of MRSA Clonal Complex 398 in Hospital and Nursing Home, Denmark.

We describe 2 fatal cases of methicillin-resistant Staphylococcus aureus (MRSA) clonal complex 398 septicemia in persons who had no contact with livestock. Whole-genome sequencing of the isolated MRSA strains strongly suggest that both were of animal origin and that the patients had been infected through 2 independent person-to-person transmission chains.
