Community-acquired pneumonia is complicated by purulent pleural effusion in approximately 28% of affected children. Its incidence has increased over the last decade. Streptococcus pneumoniae is the most frequent causal microorganism, encountered in roughly 80% of cases. We report the case of an immunocompetent 13-year-old teenager wearing orthodontic braces who suffered from pleuropneumonia due to Capnocytophaga sputigena. To date, this Gram-negative bacillus, a commensal of the buccal cavity, had never been reported to be responsible for pleural or lung infection. The clinical presentation is similar to that observed with usual bacteria, while bacterial sensitivity to betalactam antibiotics is excellent.
社区获得性肺炎在约28%的患病儿童中会并发脓性胸腔积液。在过去十年中，其发病率有所上升。肺炎链球菌是最常见的致病微生物，约80%的病例中可发现该菌。我们报告一例13岁免疫功能正常、佩戴正畸牙套的青少年，其因生痰二氧化碳嗜纤维菌感染患胸膜肺炎。迄今为止，这种革兰氏阴性杆菌作为口腔共生菌，从未被报道可导致胸膜或肺部感染。其临床表现与常见细菌感染相似，而该菌对β-内酰胺类抗生素的敏感性良好。
