Transcriptomic and phenotypic analyses suggest a network between the transcriptional regulators HrcA and [[sigma].sup.B] in Listeria monocytogenes
Article Abstract:
A series of isogenic single and double hrcA, sigB, and ctsR mutations in Listeria monocytogenes are generated in order to characterize the contributions of HrcA to Listeria monocytogenes stress response and virulence, including the potential interactions between HrcA and the HrcA regulon and other stress response regulators. The results have shown that HrcA, [[sigma].sup.B] and CtsR have formed a regulatory network that has contributed to the transcription of a number of Listeria monocytogenes genes.

Exposure to salt and organic acids increases the ability of Listeria monocytogenes to invade Caco-2 cells but decreases its ability to survive gastric stressd
Article Abstract:
An investigation on the effects of environmental stress exposure on Listeria monocytogenes growth and virulence-associated characteristics was presented. The findings suggest that virulence-associated characteristics that determine the Listeria monocytogenes infectious dose are likely to be affected by food-specific properties.

Microarray-based characterization of the Listeria monocytogenes cold regulon in log-and stationary-phase cells
Article Abstract:
Whole-genome microarray experiments are performed to define the Listeria monocytogenes cold growth regulon and to identify genes differentially expressed during growth at 4 and 37 degree C.
