Isolation of Yokenella regensburgei ('Koserella trabulsii') from a patient with transient bacteremia and from a patient with a septic knee

Abstract

Yokenella regensburgei ('Koserella trabulsii') was isolated from a 74- year-old male with a septic knee and from a 35-year-old immunocompromised female whose transient bacteremia occurred without overt signs of sepsis. Neither strain was correctly identified by laboratories using a variety of techniques.
