Catheter Related Escherichia hermannii Sepsis in a Haemodialysis Patient

Abstract

Escherichia hermanniiis an extremely rare etiological agent of invasive infection, and thus, the bacterium was initially considered non-pathogenic. However, in five previously reported case reportsE. hermanniihas been implicated as the sole pathogen. Our case report describes blood stream infection withE.hermanniiin a haemodialysis patient with persisting symptoms, high fever and inflammatory markers despite appropriate antibiotic treatment until replacement of the dialysis catheter. We suspect biofilm formation to be a crucial pathogenic feature forE. hermanniiin the maintenance of an infection, which stresses the necessity of antibiotic treatment along with catheter replacement in bloodstream- and catheter-related infection withE. hermannii.
