Scalp abscess due to Enterobacter agglomerans

Pulmonary Arteriovenous Malformations and Cerebral Abscess Recurrence in a Child With Hereditary Hemorrhagic Telangiectasia

“…agglomerans (now reclassified as Pantoea agglomerans) has never been reported as a causative agent of an HHT-related BA, but it is known as a plant pathogen responsible for human infections, due to plant-thorn-related trauma, nosocomial contamination and, more rarely, by spontaneous bacteremia, 20 even though the infection source may remain undetected. 21 Neither hospitalization nor dental care were reported at the time of the first BA, and hence we speculate that a previously overlooked exposure to soilencrusted object, plant thorn, fresh or salt water might have provided a potential entry route for this pathogen. Conversely, no bacterial agent was retrieved upon BA recurrence, likely due to the long-lasting prior antibiotic treatment, and/or the difficulty in isolating some anaerobic microorganisms.…”
