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.

In this study, we found H. alvei to be a rare significant etiologic agent of nosocomial and community-acquired infections. Hafnia alvei is a gram-negative bacterium that is rarely isolated from human specimens and is rarely considered to be pathogenic.

Hafnia alvei is a Gram-negative facultatively anaerobic bacillus that constitutes part of the human gut flora. Until recently, H. alvei strains could be mistakenly identified by conventional methods, miniaturisation or automatic systems as members of the …

Hafnia alvei is the only named species of the genus Hafnia, although organisms presently classified as H. alvei can be separated into three distinct genospecies. Unlike Edwardsiella tarda, this organism is commonly found in feces of humans and animals, as well as in sewage and soil.

Hafnia alvei is an enterobacteria initially described in 1919 by Dr. Bahr who described a bacillus that affected bees, but not laboratory mice or pygmy pigs. Later, Møller in 1954 characterized the group of enteric bacteria and gave them the name of the genus Hafnia.

H. alvei strains were more likely to be toxigenic (80% versus 47%) and express a stronger CPE (73% versus 6%) than H. paralvei isolates. The first indications of a CPE were observed in all but two strains of H. alvei as early as 48 h even though final results were not recorded until 96 h postinoculation; only one strain of H. paralvei ...

H afnia alvei is a facultative Gram-negative en teric bacillus belonging to the Enterobacteri aceae family. It is rarely considered a pathogenic organism. Although one of the enteric flora, H alvei can be a colonizer of the oropharynx and may be a cause of …

Hafnia alvei, a Gram negative motile bacillus that belongs to Enterobacteriaceae family is rarely associated with infection in pediatric patients and is exceptionally rare in the neonatal period. …
