从67例继发感染尿布皮炎的婴儿中获得的标本进行了需氧菌和厌氧菌培养。细菌生长在58。28名患者（48%）仅存在需氧兼性细菌或念珠菌属，11名患者（19%）仅存在厌氧菌，19名患者（33%）存在厌氧与需氧、兼性或酵母菌群植物群混合。回收了91个细菌或真菌分离株（每个标本1.6个），54个（每个标本0.9个）需氧菌或兼性菌，8个（每个标本0.1个）念珠菌属，严格厌氧菌31株（0.6株/标本）。主要需氧菌和兼性菌为金黄色葡萄球菌（23株）、链球菌属（16株）和大肠杆菌（6株）。优势厌氧菌为拟杆菌属（Bacteroides sp.）12株，其中脆弱拟杆菌属（Bacteroides fragilis group）9株，消化链霉菌属（Peptostrephonessp.）11株。在32例（55%）患者中回收了单一细菌分离株，其中18例为S。金黄色。在43例受试患者中，22例（51%）检测到25种产β-内酰胺酶细菌。其中包括16个S。aureus和6 B. fragilis类群。这些数据突出了厌氧菌在继发性感染尿布皮炎的多微生物性质中的重要性。
Specimens obtained from 67 infants with secondarily infected diaper dermatitis were cultured for aerobic and anaerobic bacteria. Bacteria growth was obtained in 58. Aerobic facultative bacteria or Candida sp. only were present in 28 patients (48%), anaerobic bacteria only in 11 (19%), and mixed anaerobic with aerobic, facultative, or yeast flora was present in 19 (33%). Ninety-one bacterial or fungal isolates were recovered (1.6 per specimen), 54 (0.9 per specimen) aerobic or facultative bacteria, 8 (0.1 per specimen) Candida sp., and 31 (0.6 per specimen) strict anaerobes. The predominant aerobic and facultative bacteria were Staphylococcus aureus (23 isolates), Streptococcus sp. (16), and Escherichia coli (6). The predominant anaerobes included Bacteroides sp. (12, including 9 Bacteroides fragilis group) and Peptostreptococcus sp. (11). Single bacterial isolates were recovered in 32 (55%) patients, 18 of which were S. aureus. Twenty-five beta-lactamase-producing bacteria were detected in 22 (51%) of the 43 tested patients. These included 16 S. aureus and 6 B. fragilis group. These data highlight the importance of anaerobic bacteria in the polymicrobial nature of secondarily infected diaper dermatitis.
