MRSA WGS UKM 2003 strain="MRSA_E1"

Whole genome sequencing (WGS) was applied retrospectively to an unusual spike in MRSA in two ICUs over the course of 4 weeks. While the epidemiological investigation concluded that there were two separate clusters, each associated with one ICU, spa typing data suggested a single clonal cluster (all cases shared spa type t001). Standardized gene sets were used to extract an allele-based profile for typing, and an antibiotic resistance and toxin gene profile.
