Background
Yokenella regensburgei, was firstly identified in 1984, belongs to
Enterobacteriaceae [1]. Y. regensburgei is a gram-negative,
periplasmic flagellated opportunistic pathogen that is ubiquitous in
natural environments such as soil and water. Y. regensburgei and Hafnia
alve share similar biochemical properties and thus might be
misidentified as the latter by
automated bacterial identification
systems [2]. It commonly affects immunocompromised patients, such as
patients acquired immunodeficiency syndrome and patients undergoing
treatment with corticosteroids or immunosuppressors [3-4]. Here, we
described the infection of Yokenella regensburgei in an immunocompetent
patient.
