Aspiration of retropharyngeal abscesses was performed in 14 children. Cultures were taken from aspirates for aerobic and anaerobic bacteria, and all yielded bacterial growth. Anaerobes were isolated in all patients; they were the only organisms isolated in two patients (14%) and were mixed with aerobes in 12 patients (86%). There were 78 anaerobic isolates (5.6 per specimen). The predominant anaerobes were Bacteroides species, Peptostreptococcus species, and Fusobacterium species. There were 26 aerobic isolates (1.9 per specimen). The predominant aerobes were alpha- and gamma-hemolytic streptococci, Staphylococcus aureus, Haemophilus species, and group A beta-hemolytic streptococci. beta-Lactamase production was noted in 16 isolates recovered from ten patients (71%). These included all isolates of S aureus, six of 18 Bacteroides melaninogenicus group (33%), and two of three Bacteroides oralis (67%). These findings demonstrate the major role of anaerobic organisms in retropharyngeal abscesses and the presence of beta-lactamase-producing organisms in two thirds of the patients.
对14名儿童进行了咽后脓肿抽吸术。从抽吸物中采集需氧菌和厌氧菌培养样本，所有样本均有细菌生长。所有患者均分离出厌氧菌；其中2例患者（14%）仅分离出厌氧菌，12例患者（86%）厌氧菌与需氧菌混合存在。共分离出78株厌氧菌（每个样本5.6株）。主要的厌氧菌为拟杆菌属、消化链球菌属和梭杆菌属。共分离出26株需氧菌（每个样本1.9株）。主要的需氧菌为α溶血性和γ溶血性链球菌、金黄色葡萄球菌、嗜血杆菌属和A组β溶血性链球菌。从10例患者（71%）中分离出的16株菌株检测到β-内酰胺酶产生。这些菌株包括所有金黄色葡萄球菌分离株、18株产黑色素拟杆菌属中的6株（33%）以及3株口腔拟杆菌中的2株（67%）。这些发现表明厌氧菌在咽后脓肿中起主要作用，并且三分之二的患者存在产β-内酰胺酶的细菌。
