H. alvei

Hafnia is the genus of the Enterobacteriaceae family whose only species is the Gram-negative, facultatively anaerobic, rod-shaped bacterium Hafnia alvei.

H. alvei is a commensal of the human gastrointestinal tract and not normally pathogenic, but may cause disease in immunocompromised patients. It is often resistant to multiple antibiotics, including the aminopenicillins.

The name comes from Hafnia, the Latin name for Copenhagen.
