Persistent Elizabethkingia meningoseptica bacteremia in a patient with multiple myeloma

Abstract

Elizabethkingia meningoseptica is a non-motile, gram-negative organism, previously classified as part of the Flavobacterium then Chryseobacterium genus. It has been isolated in hospital settings and has been known to cause infection, particularly in immunocompromised patients. Treatment has remained a challenge as this organism is resistant to many traditional antimicrobials used to treat gram-negative infections. We present a case of persistent E. meningoseptica bacteremia in a patient despite tailored antimicrobial therapy.
