Abstract

Study on the behaviour of five microorganisms in different formulations of Parenteral Nutrition (PN) different from each other with regard to osmolarity. The organisms investigated were Staphylococcus aureus (ATCC (12600), Bacillus subtilis (ATCC 6051), Pseudomonas aeruginosa (ATCC 9027), Enterobacter cloacae (ATCC 13047) y Candida albicans (LSH 3156 D). It was observed no direct relation between microbial growth and osmolarity in PN. C. albicans showed the best growth in all the formulations tested, followed by E. Cloacae. The number of the other microorganisms is reduced, and in general, except B. subtilis grow or are reduced in a lesser extension when the glucose solutions added are at 30 or 40%.

摘要

关于渗透压，对五种微生物在彼此不同的肠外营养（PN）不同配方中的行为进行研究。所研究的微生物有金黄色葡萄球菌（ATCC (12600)）、枯草芽孢杆菌（ATCC 6051）、铜绿假单胞菌（ATCC 9027）、阴沟肠杆菌（ATCC 13047）和白色念珠菌（LSH 3156 D）。观察到PN中微生物生长与渗透压之间无直接关系。白色念珠菌在所有测试配方中生长最佳，其次是阴沟肠杆菌。其他微生物数量减少，一般来说，当添加的葡萄糖溶液浓度为30%或40%时，除枯草芽孢杆菌外，它们的生长或减少程度较小。
