Merino trial ampc. Previously randomised in the merino 3 trial or concurrently enrolled in another therapeutic antibiotic clinical trial blood culture isolate with in vitro resistance to either meropenem or ceftolozane tazobactam known either at time of enrolment or during the course of study treatment in which case the participant will be withdrawn.
