Rayon and chemically modified cotton were compared for their effects in vitro on the physiology of a strain of Staphylococcus aureus isolated from a patient with toxic shock syndrome. Two types of experiment were carried out. The materials were used to pretreat the medium before culturing in the absence of the materials. Chemically modified cotton was either added or removed from three hour cultures and incubation continued. The rayon treated medium had little effect on growth or exoenzyme/toxin production by S. aureus. The chemically modified cotton greatly reduced growth of S. aureus and decreased exoenzyme/toxin production when added to three hour cultures. However, pretreated medium and cultures grown for three hours with the material present followed by incubation in its absence increased the exoenzyme/toxin production by S. aureus. The in vitro data suggests large effects of chemically modified cotton on the physiology of S. aureus by in some way, at present unknown, altering the growth medium.
对人造丝和化学改性棉在体外对从一名中毒性休克综合征患者分离出的金黄色葡萄球菌菌株生理学的影响进行了比较。进行了两种类型的实验。在没有这些材料的情况下培养之前，用这些材料对培养基进行预处理。在三小时培养过程中添加或去除化学改性棉，并继续孵育。经人造丝处理的培养基对金黄色葡萄球菌的生长或外酶/毒素产生几乎没有影响。当添加到三小时培养物中时，化学改性棉极大地降低了金黄色葡萄球菌的生长并减少了外酶/毒素的产生。然而，用存在该材料的培养基预处理并在不存在该材料的情况下培养三小时的培养物增加了金黄色葡萄球菌的外酶/毒素产生。体外数据表明，化学改性棉通过以目前未知的某种方式改变生长培养基，对金黄色葡萄球菌的生理学有很大影响。
