Dispersal of non-sporeforming anaerobic bacteria was studied. Skin samples were taken from the subjects, and dispersed from different parts of the body was examined. The number of anaerobic bacteria dispersed was not correlated to their density on the surface of skin area exposed. The highest density of anaerobic bacteria on the skin was found in the face and upper trunk, but the highest yield of anaerobic bacteria dispersed came from the lower trunk. The dominant anaerobic bacteria dispersed were Propionibacterium acnes, but Propionibacterium avidum, Propionibacterium granulosum and Gram-positive cocci were also isolated from the dispersal samples. Peptococcus magnus was the most common coccus isolated. For the less frequently isolated bacteria, the best correlation was found between the perineal flora and airborne bacteria. A comparison was also made of bacterial dispersal by naked and dressed subjects. The dispersal of both aerobic and anaerobic bacteria was higher when the subjects were dressed in conventional operating theatre cotton clothing than when they were naked. The increased dispersal of anaerobic bacteria when the subjects were dressed was mainly due to increased dispersal of Propionibacterium sp.
对非芽孢形成厌氧菌的扩散进行了研究。从受试者身上采集皮肤样本，并对身体不同部位的扩散情况进行检查。扩散的厌氧菌数量与其在暴露皮肤区域表面的密度无关。皮肤表面厌氧菌密度最高的部位是面部和上躯干，但扩散的厌氧菌产量最高的部位是下躯干。扩散的主要优势厌氧菌是痤疮丙酸杆菌，但在扩散样本中也分离出了贪婪丙酸杆菌、颗粒丙酸杆菌和革兰氏阳性球菌。巨大消化球菌是最常分离出的球菌。对于较少分离出的细菌，会阴部菌群与空气传播细菌之间的相关性最佳。还对裸体和着装受试者的细菌扩散情况进行了比较。当受试者穿着传统手术室棉质服装时，需氧菌和厌氧菌的扩散均高于裸体时。受试者着装时厌氧菌扩散增加主要是由于丙酸杆菌属扩散增加所致。
