Abstract
Pseudomonas cepacia (Ps. multivorans) can become adapted to a 1 in 30 dilution of Savlon hospital concentrate in distilled water, and can multiply in it. The organism so adapted did not survive in Savlon of the same strength made with hard tap water (pH 7.2). This effect was due to the difference of pH between the two solutions. At the pH of the distilled water solution (pH 6.0) Savlon also showed reduced activity against Proteus vulgaris, but activity against Ps. aeruginosa was not affected.
摘要
洋葱伯克霍尔德菌（多食伯克霍尔德菌）能够适应在蒸馏水中1:30稀释的Savlon医院浓缩液，并能在其中繁殖。如此适应的该微生物在由硬自来水（pH 7.2）配制的相同浓度的Savlon中无法存活。这种效应是由于两种溶液的pH值差异所致。在蒸馏水溶液的pH值（pH 6.0）下，Savlon对普通变形杆菌的活性也有所降低，但对铜绿假单胞菌的活性未受影响。
