Escherichia hermannii is an extremely rare etiological agent of
invasive infection, and thus, the bacterium was initially considered
non-pathogenic. However, in five previously reported case reports E.
hermannii has been implicated as the sole pathogen. Our case report
describes blood stream infection with E.hermannii in 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 for E. hermannii in the maintenance of an infection, which
stresses the necessity of antibiotic treatment along with catheter replacement
in bloodstream- and catheter-related infection with E. hermannii.
