Aspirates of pus from infected pilonidal sinuses in 75 patients showed bacterial growth. Anaerobic bacteria only were recovered in 58 (77%) specimens, aerobic bacteria only in three (4%), and mixed aerobic and anaerobic bacteria in 14 (19%). Two hundred and nine isolates were recovered: 147 anaerobes (2.0 isolates a specimen) and 62 aerobes (0.8 a specimen). The predominant anaerobes were Bacteroides sp (81 isolates, including 29 Bacteroides fragilis group) and 51 anaerobic cocci. The predominant aerobes were Escherichia coli (n = 15), Proteus sp (n = 9), group D streptococcus (n = 7), and Pseudomonas sp (n = 7). This study highlights the polymicrobial nature and predominance of anaerobic bacteria in infected pilonidal sinuses.
对75例感染性藏毛窦的脓液抽吸物进行检测，结果显示有细菌生长。仅培养出厌氧菌的标本有58份（77%），仅培养出需氧菌的有3份（4%），培养出需氧菌和厌氧菌混合菌的有14份（19%）。共分离出209株菌株：147株厌氧菌（每份标本分离出2.0株）和62株需氧菌（每份标本分离出0.8株）。主要的厌氧菌是拟杆菌属（81株，包括29株脆弱拟杆菌群）和51株厌氧球菌。主要的需氧菌是大肠杆菌（n = 15）、变形杆菌属（n = 9）、D组链球菌（n = 7）和假单胞菌属（ n = 7）。本研究强调了感染性藏毛窦中细菌的多菌性本质以及厌氧菌的优势地位。
