“…Despite the fact that most strains of H. alvei can be easily identified using commercial systems, conventional biochemical test results can be necessary under a number of circumstances. These include when probability of a correct identification is low, when H. alvei strains with two or more atypical properties (e.g., VP negative and urease positive) are identified, when hafniae are isolated from an anatomic site not traditionally associated with this species (e.g., blood), for unusual disease syndromes linked to Hafnia infection, for chronic or recurring illnesses, and for publication 22 JANDA AND ABBOTT CLIN.

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. Despite the fact that the genus currently contains only a single species (H. alvei), more extensive phylogenetic depth (two or more species) is apparent based upon DNA relatedness and 16S rRNA gene sequencing studies. Hafnia causes a variety of systemic infections, including septicemia and pneumonia; however, its role as a gastrointestinal pathogen is controversial. Many of the data supporting a role for hafniae as enteric pathogens were incorrectly attributed to this genus rather than to the actual pathogen, Escherichia albertii. There are numerous gaps in our understanding of this genus, including ecologic habitats and population genetics, disease-producing role in animals, phenetic and genetic methods useful in distinguishing genomospecies within the H. alvei complex, and bona fide pathogenicity factors.

“…In adults, H alvei has caused bacteremia [9,10], pneumonia, and nosocomial wound infections [11][12][13]. H. alvei was recovered with Salmonella arizonae from a patient with endogenous endophthalmitis who was receiving steroids [14]. Recently, H alvei was isolated from a buttock abscess that resulted from skin puncture with carpet nails in an otherwise healthy middle-aged man [15].…”

Hafnia alvei is a gram-negative bacterium that is rarely isolated from human specimens and is rarely considered to be pathogenic. It has been associated with gastroenteritis, meningitis, bacteremia, pneumonia, nosocomial wound infections, endophthalmitis, and a buttock abscess. We studied 80 H. alvei isolates recovered from 61 patients within a period of 30 months. H. alvei was cultured from sites that included the respiratory tract (n = 38), the gastrointestinal tract (n = 16), and the urogenital tract (n = 12); the organism was found in blood cultures (n = 8), on central venous catheters (n = 3), and on the skin (n = 3). Only 25% of H. alvei isolates were recovered in pure cultures. Fifty-seven (93.4%) of the patients had an underlying illness. H. alvei proved to be the etiologic agent in two episodes of septicemia and in one episode of peritonitis and was probably responsible for septicemia in two other patients and pneumonia in one. All six of these patients recovered after receiving antibiotic treatment and/or standard surgical treatment, when needed. Three of these infections were nosocomial, and three were community acquired. Of the strains of H. alvei tested in our study, 100% were susceptible to netilmicin, ciprofloxacin, and imipenem; 92% were susceptible to piperacillin; 90% were susceptible to co-trimoxazole; and 88% were susceptible to ceftriaxone and ceftazidime. In this study, we found H. alvei to be a rare but significant etiologic agent of nosocomial and community-acquired infections.

“…Systemic risk factors were reported in three cases: one having chronic lymphocytic leukemia (CLL) on chemo therapy, 11 one was HIV positive, 15 and one had rheuma toid arthritis 13 in which the author ascribed infection due to use of snake powder as a seasoning for food. Systemic risk factors were noted to be absent in five cases.…”

Endogenous endophthalmitis is a rare but serious condition that occurs when bacteria cross the blood-ocular barrier and multiply within the eye. We provide a literature review of Salmonella endogenous endophthalmitis by reviewing eight reported cases and integrating this with our experience of one case in which a four-year-old child presented with acute endophthalmitis of four days duration. He had suffered typhoid fever two months back. Vitreous biopsy revealed Salmonella typhi. Despite aggressive surgical and medical treatment, the eye developed retinal necrosis, detachment, and phthisis. Blood, aqueous, and vitreous cultures were the most frequent means of establishing the diagnosis in the reported cases. The visual outcome in most cases of endogenous Salmonella endophthalmitis is blindness in the affected eye, which has not improved since its first report in 1979. Endogenous endophthalmitis due to Salmonella typhi should be incorporated into standard literature on complications of acute and relapse phases of typhoid fever.
