“…Interestingly, in our case we observed multiple small abscess formations in the course of pneumonia, which could be treated with antibiotics without surgical intervention and showed almost complete resolution in the recent follow-up. A similar radiological pattern as in our case was observed by Castellanos et al [10] showing in part cavitation and abscessing. Since S. aureus was detected in the initial tracheal aspirate it may have contributed to the clinical and radiological picture as a co-pathogen or even as the culprit.…”

“…Our patient became severely ill, needed prolonged mechanical ventilation and intensive care treatment, despite lack of risk factors in the personal history apart of being obese. Castellanos and colleagues described a severe pneumonia due to an infection of D. pneumosintes in a patient with COPD [10] and Bahrani-Mougeot and colleagues identified D. pneumosintes among other pathogens in a trauma patient with ventilation-associated pneumonia [11]. Overall, our clinical case shows that an immunocompetent patient with no personal history of pulmonary disease can suffer from severe clinical courses due to D. pneumosintes.…”

“…In 4 out of 10 cases, D. pneumosintes could be identified through cultivation of material obtained via intervention. Out of these four, D. pneumosintes was cultivated in two cases with pneumonia from a bronchoalveolar lavage [10,11] and in the other two cases from pus of a drained brain abscess and liver [14,16]. In total 6 of the 10 reviewed cases needed surgical treatment [6,[13][14][15][16].…”

Background: Dialister pneumosintes (D. pneumosintes) is known to cause dental, periodontal or sinus infections. To date, the pathogen has only been described in a small number of cases with a severe infection. Case report: We describe the clinical case of a 13-year-old, obese female patient that presented with acute respiratory failure and sepsis. A CT-scan showed extensive bilateral patchy areas, subpleural and peribronchovascular consolidations with surrounding ground-glass opacity, extensive consolidations in the lower lobes of both lungs matching to a severe pneumonia and clinically emerging acute respiratory distress syndrome. Moreover, it showed extensive sinusitis of the right sinus frontalis, maxillaris and right cellulae ethmoidales. D. pneumosintes was isolated from an anaerobic blood culture obtained at admission. The antibiotic treatment included piperacillin/tazobactam and oral switch to ampicillin/sulbactam plus ciprofloxacin. Conclusions: We describe the first adolescent with severe systemic D. pneumosintes infection. Since the pathogen is difficult to culture the systemic virulence remains unclear. This work aims to sensitize health care specialists to consider D. pneumosintes infection in patients with periodontal or sinusal infection.

Background Dialister pneumosintes is an anaerobic, Gram negative bacillus, found in the human oral cavity and associated with periodontitis. It has also been isolated from gastric mucosa and stool samples. Recent case reports implicate D. pneumosintes in local infection such as dental root canals, sinusitis, Lemierres syndrome and brain abscesses, as well as distal infections of the liver and lung through haematogenous spread. Case presentation We present a novel case of aortic graft infection and aortoenteric fistula (AEF) in a 75 year old Caucasian male, associated with D. pneumosintes bacteraemia. Microbiological evaluation of septic emboli in the lower limbs revealed other gastrointestinal flora. This suggests either AEF leading to graft infection and subsequent distal emboli and bacteraemia, or a dental origin of infection which seeded to the graft, resulting in AEF and systemic infection. To our knowledge this is the first report of D. pneumosintes associated aortic graft infection. The patient underwent surgical explantation, oversew of the aorta and placement of extra-anatomical bypass graft in conjunction with antimicrobial therapy, making a good recovery with discharge home after a 35-day hospital admission. Conclusion We report a case of Dialister pneumosintes bacteraemia associated with aortic graft infection. To our knowledge, vascular graft-associated infection with D. pneumosintes has not been reported before.
