摘　　要：目的 :了解木浆水刺布对细菌的屏障作用。方法 :将木浆水刺布及市售白棉布叠成 1～ 4层 ,分别铺在培养基表面 ,于干燥和潮湿状态下在布上滴加不同稀释度的大肠埃希菌和金黄色葡萄球菌菌液 ,培养后记录菌落数。结果 :在干燥和潮湿状态下木浆水刺布 1层即可防止细菌透过 ;市售白棉布 1层在干燥和潮湿状态下均有细菌透过 ,潮湿状态下细菌更易通过 ,叠加到4层才有肯定的屏障作用。结论Objective:To observe the barrier of wood pulp spunlace against bacteria.Methods:One to four layers of wood pulp spunlace or white cotton cloth from market were put on the surface of culture medium plate.Suspension of E.coli and S.aureus at different dilution were dropped on the dried or wet cloths.After culture,the numbers of bacteria colonies were counted.Results:One layer of dried or wet wood pulp spunlace were able to,but white cotton cloth from market did not,prevent permeation from bacteria.Only four layers of dried white cotton cloth from market were able to prevent the permeating from the bacteria.Conclusions:Wood pulp spunlace had a better barrier function against bacteria than that of white cotton cloth from market.
