DOI: 10.1002/jobm.201900076

Abstract: A bacterium's ability to thrive in the presence of multiple environmental stressors simultaneously determines its resilience. We showed that activation of the SigB‐controlled general stress response by mild environmental or energy stress provided significant cross‐protection… read more here.

DOI: 10.1016/j.micpath.2018.12.019

Abstract: Sigma factor B (SigB) controls the expression of Staphylococcus aureus genes including virulence factors and plays a role in the bacterial secretion system through membrane vesicle production. Inhibition of SigB could attenuate SigB dependent virulence… read more here.

DOI: 10.1128/iai.00571-22

Abstract: Listeria monocytogenes is a bacterial pathogen capable of causing severe infections but also thriving outside the host. To respond to different stress conditions, L. monocytogenes mainly utilizes the general stress response regulon, which largely is… read more here.

DOI: 10.1128/jb.00486-21

Abstract: Pathogenic bacteria need to sense and respond to stresses to survive harsh environments and also be able to turn off the response when no longer facing stress. Activity of the stress sigma factor SigB in… read more here.

DOI: 10.1128/mbio.02274-24

Abstract: ABSTRACT Seemingly simple bacteria mount intricate adaptive responses when exposed to physical stress or nutrient limitation, and the activation of these responses is governed by complex signal transduction networks. Upon entry into the stationary growth… read more here.

DOI: 10.3390/pathogens6030031

Abstract: Staphylococcus aureus is a major pathogen causing bone infections that can become chronic and difficult to treat. Recently, we described the mechanism employed by S. aureus to switch to small colony variants (SCVs) and trigger… read more here.
