meat determined with a … Hafnia alvei is a gram-negative bacterium that is rarely isolated from human specimens and is rarely considered to be pathogenic. causes nosocomial and community-acquired infections (13). The species has been known by the names Enterobacter hafnieae, Bacterium cadaveris, Bacillus asiaticus and B. paratyphi alvei.Hafnia is the old name for Copenhagen. SUMMARY The genus Hafnia , a member of the family Enterobacteriaceae , consists of gram-negative bacteria that are occasionally implicated in both intestinal and extraintestinal infections in humans. Hafnia alvei is a Gram-negative enteric and oropharyngeal rod that is infrequently involved with infection. • H. alvei may cause nosocomial and community-acquired in-fections. It has been associated with gastroenteritis, meningitis, bacteremia, pneumonia, nosocomial wound infections, endophthalmitis, and a buttock abscess. This genus belongs to the Enterobacteriaceae family and includes two known species (alvei and paralvei) [].Since its discovery more than 50 years ago, very little has been determined about variations among Hafnia species. We studied 80 H. alve … We report on a renal transplant patient who developed H. alvei pyelonephritis and urosepsis.

Infections caused by Hafnia are usually considered nosocomial. The epithet alvei is chosen because the bacterium has been isolated from the intestinal tract of honey bees. This organism is a causative agent of intestinal disorders and is found in different environments. ABSTRACT:BACKGROUND:The genus Hafnia , a member of the family Enterobacteriaceae, consists of Gram negative bacteriathat are occasionally implicated in both intestinal and extraintestinal infections in human. Hafnia alvei is the only species in the Hafnia genus. Hafnia is a common genus of gram-negative bacteria found in the environment on plants and foods as well as in the gastrointestinal tracts of mammals. Hafnia alvei. Hafnia alvei is a gram-negative facultatively anaerobic bacillus that belongs to the family Enterobacteriaceae . ... Hafnia alvei and other Enterobacteriaceae isolated from refrigerated . Urinary Tract Infection Caused by Hafnia Alvei 251 Main Points • Hafnia alvei, belonging to the Enterobacteriaceae family, was identified in 1954 and is the only species in the genus Hafnia.

Hafnia alvei, a member of the family Enterobacteriaceae, was the only species of bacteria cultured from the stool of a 9-month-old child who was admitted with a 3-day history of watery diarrhea. Turk J Nephrol 2020; 29(3): 250-2 Alaygut et al. H. alvei has received increased clinical attention as a cause of different infections in humans. The source of infection remains enigmatic but is most likely the intestinal tract.
