Abstract

The study of the effects of osmolarity and growth phase on Salmonella typhi adherence to and invasion of Henle 407 epithelial cells provides the first evidence of a clear overlap between these two environmental stimuli. High-osmolarity conditions are required in the late-log phase for optimum induction of the adherent and invasive phenotypes.

摘要

关于渗透压和生长阶段对伤寒沙门氏菌黏附及侵袭亨勒407上皮细胞影响的研究,首次证明了这两种环境刺激之间存在明显重叠。在对数生长期后期,需要高渗条件才能最佳诱导黏附及侵袭表型。
