The intracellular and extracellular protease and elastase contents of Pseudomonas aeruginosa were studied in relation to the age of the culture. The intracellular protease and elastase content of the organisms decreased as the culture grew older, whereas extracellular protease and elastase greatly increased 24 h after incubation commenced, suggesting that host tissue injury by P. aeruginosa infection may increase in proportion to the duration of tissue colonisation.
研究了铜绿假单胞菌细胞内和细胞外蛋白酶及弹性蛋白酶含量与培养时间的关系。随着培养时间延长，该菌的细胞内蛋白酶和弹性蛋白酶含量降低，而在培养开始24小时后，细胞外蛋白酶和弹性蛋白酶大幅增加，这表明铜绿假单胞菌感染对宿主组织的损伤可能与组织定植持续时间成正比增加。
