摘要
为了解３种空气细菌采样方法的差别，在医院同一室内，同步进行３种方法采样。结果，消毒前空气细菌总数较多，ＪＷＬ—ⅡＡ型空气采样器所采菌数较少，Ｐｏｔｏｎ空气采样器者次之，平板自然沉降所采菌数较多；消毒后空气细菌总数减少，Ｐｏｔｏｎ空气采样器所采菌数较少，平板自然沉降所采菌数仍较多。Ｐｏｔｏｎ空气采样器所采菌量，随着空气细菌总数增多而接近或超过ＪＷＬ—ⅡＡ型空气采样器者。
In order to know the difference of 3 air bacteria sampling methods, synchronous sam- pling by 3 methods was carried out in a same room of a hospital. The results showed that the total bacterial count of air was high before disinfection and the number of bacteria collected was small by JWL-Ⅱ A-type air sampler, next by Poton air sampler and large by plate natu- ral sedimentation. After disinfection, the total bacterial count of air decreased and the number of bacteria collected was small by Poton air sampler and still large by plate natural sedimentation. The number of bacteria collected by Poton air sampler approximated or ex- ceeded that collected by JWL-Ⅱ A-type air sampler with increase in total bacterial count of air.
