Elizabethkingia anophelis has recently emerged as a cause of life-threatening infections in humans. We aimed to investigate the clinical and molecular characteristics of E. anophelis.

A clinical microbiology laboratory database was searched to identify patients with Elizabethkingia infections between 2005 and 2016. Isolates were re-identified and their species were confirmed using 16S rRNA gene sequencing. Patients with E. anophelis infections were included in this study. Clinical information, antimicrobial susceptibility and mutations in DNA gyrase and topoisomerase IV were analysed.

A total of 67 patients were identified to have E. anophelis infections, including 47 men and 20 women, with a median age of 61 years. Comorbidity was identified in 85.1% of the patients. Among the 67 E. anophelis isolates, 40 (59.7 …
