Spleen abscess caused byEikenella corrodens

Abstract

A case is reported of splenic abscess due to Eikenella corrodens, a gram-negative rod which is found as part of normal flora in human mucous surfaces. A 64-year-old man presented with fever, chills, anorexia and abdominal pain. Abdominal ultrasound examination showed a perisplenic fluid collection which was considered to be either blood or a subcapsular spleen abscess. The presence of a splenic abscess was later confirmed during surgery and a splenectomy was performed. Splenic purulent material and blood cultures yielded Eikenella corrodens. The patient received cefotaxime for 19 days and was discharged asymptomatic.

Inflammatory pseudotumour associated with chronic persistent Eikenella corrodens infection: a case report and brief review

“…It is a fastidious, slow growing, human commensal bacillus, capable of acting as an opportunistic pathogen and causing abscesses in several anatomical sites, including the liver, [3][4][5] lung, 6 spleen, 7 and submandibular region, 8 as demonstrated by our present case. The patient's previous oesophageogastrectomy with colon bypass for her corrosive injuries may have contributed to bacterial spreading via the damaged gastrointestinal mucosal barrier.…”

“…Eikenella corrodens is a rarely isolated Gram negative, facultatively anaerobic, fastidious bacillus. [2][3][4][5][6][7][8][9] Although it is part of the normal flora of the human oral cavity, upper respiratory tract, and gastrointestinal and genitourinary tracts, [2][3][4][5][6] its potential to act as a pathogen has been well documented. [2][3][4][5][6] ''Although inflammatory pseudotumours usually have a benign evolution, with the occasional documented infective cause, the prognosis of a minority of cases is poor''…”

DNA fingerprinting of Eikenella cormdens by pulsed‐field gel electrophoresis

“…Its potential pathogenicity for hutnans is indicated by the fact that it might cause serious infections where it is recovered either as the sole infecting organism or combined with other bactei'ia. E. corrodetts strains were identified in patients with septicemia (13), arthritis (12), endocarditis (10), meningitis, pneumonia and ab-scesses (7,15,18) and osteomyelitis (22). Some of these infections were caused by dental extraetions ( 12), human bites (22) or fist-fight injuries (22).…”
