Abstract:
Background: Elizabethkingia meningoseptica, formerly known as Chryseobacterium meningosepticum, is a non-motile, non-fastidious, catalase and oxidase-positive, aerobic, glucosenon- fermentative, Gram-negative bacillus that was first defined by Elizabeth O. King in 1959. It has emerged as an opportunistic pathogen that has infected patients in extreme age groups and immunocompromised individuals, especially in intensive care settings. There has been an increased interest in this pathogen due to its increasing occurrence around the world, ubiquitous nature, and inherent capacity for antimicrobia

Abstract Background: Although Elizabethkingia meningoseptica (Chryseobacterium meningosepticum) infections in immunocompromised hosts have been recognised, clinical data detailing these infections remain limited, especially from India. Antimicrobial susceptibility data on E. meningoseptica remain very limited, with no established breakpoints by Clinical and Laboratory Standards Institute (CLSI). The organism is usually multidrug resistant to antibiotics usually prescribed for treating Gram-negative bacterial infections, a serious challenge to the patient and the treating clinicians.

Abstract:
Elizabethkingia meningoseptica and Elizabethkingia anophelis are two major pathogens in the genus Elizabethkingia. Studies have revealed that Elizabethkingia anophelis is frequently misidentified as E. meningoseptica. Therefore, our aim was to explore the clinical and molecular differences between these two species. The database of a clinical microbiology laboratory in a university-affiliated hospital of Taiwan was searched to identify patients with Elizabethkingia infections between January 2005 and June 2018. Species were reidentified using 16S ribosomal RNA gene sequencing. Twenty E. mening
