Aspirates of 16 acutely infected and 7 chronically infected sphenoid sinuses were processed for aerobic and anaerobic bacteria. A total of 29 isolates were recovered from the 16 cases of acute sphenoid sinusitis (1.8 per specimen): 22 aerobic and facultative (1.4 per specimen), and 7 anaerobic (0.4 per specimen). Aerobic and facultative organisms alone were recovered in 10 specimens (62%), anaerobes alone were isolated in 3 (19%), and mixed aerobic and anaerobic bacteria were recovered in 3 (19%). The predominant aerobic and facultative species were Staphylococcus aureus (9 isolates), Streptococcus spp (9), and Haemophilus influenzae (2). A total of 28 isolates were recovered from the 7 cases of chronic sphenoid sinusitis (4.0 per specimen): 11 aerobic and facultative (1.6 per specimen) and 17 anaerobic (2.4 per specimen). Aerobic and facultative organisms alone were recovered in I instance (14%), anaerobes alone in 3 instances (43%), and mixed aerobes and anaerobes in 3 instances (43%). The predominant aerobic bacteria were gram-negative bacilli (Klebsiella pneumoniae, Escherichia coli, and Pseudomonas aeruginosa; 1 each). The predominant anaerobes included Peptostreptococcus spp (4 isolates), Prevotella spp (5), and Fusobacterium spp (4). These findings illustrate the unique microbiology of acute and chronic sphenoid sinusitis.
对16例急性感染和7例慢性感染的蝶窦进行穿刺取样，检测需氧菌和厌氧菌。从16例急性蝶窦炎病例中共分离出29株菌株（每个样本1.8株）：22株需氧菌和兼性菌（每个样本1.4株），7株厌氧菌（每个样本0.4株）。仅分离出需氧菌和兼性菌的样本有10例（62%），仅分离出厌氧菌的有3例（19%），需氧菌和厌氧菌混合感染的有3例（19%）。主要的需氧菌和兼性菌为金黄色葡萄球菌（9株）、链球菌属（9株）和流感嗜血杆菌（2株）。从7例慢性蝶窦炎病例中共分离出28株菌株（每个样本4.0株）：11株需氧菌和兼性菌（每个样本1.6株），17株厌氧菌（每个样本2.4株）。仅分离出需氧菌和兼性菌的有1例（14%），仅分离出厌氧菌的有3例（43%），需氧菌和厌氧菌混合感染的有3例（43%）。主要的需氧菌为革兰氏阴性杆菌（肺炎克雷伯菌、大肠杆菌和铜绿假单胞菌各1株）。主要的厌氧菌包括消化链球菌属（4株）、普雷沃菌属（5株）和梭杆菌属（4株）。这些发现说明了急性和慢性蝶窦炎独特的微生物学特征。
