Background: Globicatella sanguinis is an emerging pathogenic rarely recognized as a cause of infection. The objective of this work was to investigate the involvement of this bacterium in endodontic infections in Burkina Faso and to determine its susceptibility to antibiotics.
Materials and methods: It was a cross-sectional descriptive study conducted at the Municipal Oral Health Center of Ouagadougou, from June to October 2014. Clinical data were collected using a sheet. Bacteria were isolated by the method of streaking on selective medium and identification was done by API 20 Strep gallery. Antibiotic susceptibility was determined by the diffusion method on solid medium.
Results: A total of 125 patients were received with a significant proportion for the age group of 19 to 40 years (55.2%). Apical periodontitis accounted for 50.4% and endodontic cellulitis accounted for 49.6%. Five isolates of Globicatella sanguinis have been identified. They were resistant (100%) to cefotaxime, metronidazole and penicillin G. Spiramycin showed an intermediate sensitivity of 60%. Isolates showed good sensitivity (100%) to trimethoprim-sulfamethoxazole, amoxicillin-clavulanic acid and tazobactam-piperacillin. One of them produced extended spectrum β-lactamases.
Conclusion: The severity of infections that is responsible Globicatella sanguinis reflects difficulties to eradicate these bacteria from root canal system.
