The bacterial flora of 20 headset devices were evaluated before and after they were worn for 1 hour. Bacteria were recovered from all headsets, and their number increased from a mean (+/- standard deviation) of 60 +/- 5 organisms per device to 650 +/- 51 organisms per device (P less than .001). The predominant organisms recovered were Staphylococcus spp, Streptococcus spp, Propionibacterium spp, and Peptostreptococcus spp. This study demonstrates the presence of potential pathogens in headset devices, as well as the increase in the number of these pathogens after the headsets have been worn for 1 hour.
对20个耳机设备佩戴1小时前后的细菌菌群进行了评估。所有耳机均检测出细菌,其数量从每个设备平均(±标准差)60±5个菌增加到每个设备650±51个菌(P<0.001)。检出的主要细菌有葡萄球菌属、链球菌属、丙酸杆菌属和消化链球菌属。本研究证明了耳机设备中存在潜在病原体,以及耳机佩戴1小时后这些病原体数量的增加。
