A Case of Coinfection in a Chronic Maxillary Sinusitis of Odontogenic Origin: Identification of Dialister pneumosintes

摘要: Abstract Introduction In this report, we discuss the case of a 39-year-old woman presenting with chronic maxillary sinusitis. Methods Dialister pneumosintes , Staphylococcus epidermidis and Peptostreptococcus spp . were isolated from endosinusal samples obtained during surgery. The patient showed extensive periodontopathy had undergone prior endodontic treatment for infection teeth #13, #14, #15, which failed presumably acted as bridge sinusal infection. After nasosinusal surgery, consisting opening toilet sinus, combined extraction 3 previously mentioned antibiotic treatment, complete healing. Results S. spp. identified traditional biochemical test confirmed by pyrosequencing. Conversely, D. could not be conventional method, but it was using DNA addition, to better understand role virulence bacterium in odontogenic sinusitis, have evaluated ability produce biofilms onto inert surfaces. is known periodontal pathogen found necrotic pulp, subgingival plaque, deep pockets. Conclusions To our knowledge, pathogenic sinusitis has never been evidenced. Thus, its detection specimens may provide significant insight into pathogenesis relevant medical condition.
