Emergence of pstS-Null Vancomycin-Resistant Enterococcus faecium Clone ST1478, Canada, 2013-2018.

Rates of vancomycin-resistant enterococci bloodstream infections have remained relatively low in Canada. We recently observed an increase of 113% in these infections rates, which coincided with emergence of Enterococcus faecium pstS-null sequence type 1478. The proportion of this sequence type increased from 2.

The diabetic foot clinic: not a significant source for acquisition of methicillin-resistant Staphylococcus aureus.

Background: Diabetic foot clinics have been reported as a source of acquisition of methicillin-resistant Staphylococcus aureus (MRSA). We undertook a 10-year review of patients infected or colonized with MRSA from a tertiary care hospital diabetic foot clinic and describe the epidemiology and genotypes of newly acquired MRSA in comparison with the community at large.

Methods: All new MRSA cases from the diabetic foot clinic, the hospital, and the province were reviewed to identify and compare the 10-year trend in MRSA incidence.

Vancomycin-resistant enterococci in Canada: results from the Canadian nosocomial infection surveillance program, 1999-2005.

Surveillance for vancomycin-resistant enterococci (VRE) in sentinel Canadian hospitals has been conducted since 1999. From 1999 to 2005, the rate of VRE detection increased from 0.37 to 1.
