Aspirate of pus from eight subperiosteal orbital abscesses (SPOAs) and their corresponding infected sinuses were studied for aerobic and anaerobic bacteria. Polymicrobial flora was found in all instances, and the number of isolates varied from two to five. Anaerobes were recovered from all specimens. The predominant isolates were Peptostreptococcus spp, Prevotella spp, Fusobacterium spp, Staphylococcus aureus, and microaerophilic streptococci. Concordance in the microbiological findings between SPOA and the infected sinus was found in all instances. However, certain organisms were only present at one site and not the other. Fourteen beta-lactamase-producing organisms were present in nine specimens. These data confirm the importance of anaerobic bacteria in sinusitis and demonstrate their predominance in the associated SPOA.
对8例眶骨膜下脓肿（SPOA）及其相应感染鼻窦的脓液进行需氧菌和厌氧菌研究。所有病例均发现多菌丛，分离菌株数量从2种到5种不等。所有标本均培养出厌氧菌。主要分离菌株为消化链球菌属、普雷沃菌属、梭杆菌属、金黄色葡萄球菌和微需氧链球菌。所有病例中，SPOA和感染鼻窦的微生物学检查结果均一致。然而，某些微生物仅在一个部位存在，而在另一个部位不存在。9份标本中存在14株产β-内酰胺酶的微生物。这些数据证实了厌氧菌在鼻窦炎中的重要性，并表明它们在相关眶骨膜下脓肿中占主导地位。
