Elizabethkingia meningoseptica as an Unusual Pathogen Causing Healthcare-associated Bacteriuria

Elizabethkingia meningoseptica is recovered from urine samples in very unusual cases, although the clinical significance of its detection remains unclear. Four cases of E. meningoseptica bacteriuria were analyzed, and E. meningoseptica was found to be the causative agent of healthcare-associated bacteriuria, including urinary tract infections, asymptomatic bacteriuria and transient bacteriuria, primarily in elderly patients with diabetes. Although E. meningoseptica cultured from urine was found to be resistant to most antimicrobial agents, bacteriuria caused by E. meningoseptica resolved in all four cases. However, instances of death have also been previously reported.
