The impact of geography and antimicrobial resistance on the incidence and outcomes of Elizabethkingia species bloodstream infection

We conducted a 20-year statewide cohort of 115 Elizabethkingia bloodstream infections in Queensland, Australia. Incidence was ∼9-fold higher in tropical vs temperate regions, with 61 % community-onset. Ciprofloxacin susceptibility was 74.8 %. Thirty-day mortality was 14.9 %, and ciprofloxacin resistance independently predicted death, though interpretation is limited without treatment data.
