Isolates were collected from hospitals and their associated clinical microbiology laboratories in 37 countries during a six-month period. Both resistant and comparator susceptible isolates were collected. The WGS data will be used to analyse the population structure, with particular emphasis on the identification of high-risk clones. It will also be used to determine the prevalence, distribution and transmission dynamics of key resistance and virulence markers.
