A new surface sampling method, the velvet pad rinse technique, was compared with the velvet pad imprint method, in a randomized bacteriological sampling trial, using surgical wounds to evaluate quantitative results. The efficiency of bacterial recovery was increased 20-fold by the new technique, and the improvement was ascribed in particular to the introduction of a procedure of rinsing the velvet pad after sampling.
在一项随机细菌采样试验中,将一种新的表面采样方法——天鹅绒垫冲洗技术与天鹅绒垫印迹法进行了比较,使用手术伤口来评估定量结果。新技术使细菌回收效率提高了20倍,这种改进尤其归因于采样后引入了冲洗天鹅绒垫的程序。
