细菌性蜂窝织炎是一种常见病，病原学诊断往往是徒劳的，经验性治疗意见不一。本研究的目的是确定在急诊室环境中细菌性蜂窝织炎的主要微生物学原因。对89例有蜂窝织炎临床表现的94例患者进行了研究。74例感染闭合，22例合并开放性皮肤病变。使用Cameco手柄，采用抽吸空气缓冲技术抽吸感染部位，以便于操作和稳定抽吸针。排除污染样本后，30例（31.9%）获得阳性培养物。30.6%的开放性病变和36.4%的闭合性病变培养阳性。金黄色葡萄球菌是最常见的病原体，有11例，S。表皮葡萄球菌8例，A群β-溶血性链球菌5例。所有鼠伤寒沙门金黄色葡萄球菌对甲氧西林敏感，仅1株对青霉素敏感。最常见的感染部位是下肢（59%）。根据这些数据，成人细菌性蜂窝织炎的最佳初始治疗应该是同时对葡萄球菌和链球菌有活性的药物。
Bacterial cellulitis is a common problem, etiologic diagnosis often unrewarding and opinions differ on empiric therapy. The purpose of this study was to determine the major microbiologic causes of bacterial cellulitis in a walk-in Emergency Room setting. 94 cases in 89 patients with clinical signs of cellulitis were studied. The infection was closed in 74 cases and associated with an open skin lesion in 22. The infection site was aspirated with a suction air-buffer technique employing a Cameco handle for easier handling and stabilization of the aspiration needle. After exclusion of contaminated samples, positive cultures were obtained from 30 cases (31.9%). Cultures were positive in 30.6% of open lesions and in 36.4% of closed ones. Staphylococcus aureus was the most common organism, present in 11 cases, S. epidermidis in 8 and group A beta-hemolytic streptococci in 5. All S. aureus strains were methicillin-sensitive and only 1 was sensitive to penicillin. The most common site of infection was the lower extremity (59%). According to these data the optimal initial therapy for bacterial cellulitis in adults should be with drugs active against both staphylococci and streptococci.
