During infection occurs modulation of gene expression in both pathogen and host. Chromobacterium violaceum is an opportunistic pathogen that causes severe infections characterized by septicemia that can lead to death. However, no study characterized in a global way alterations in gene expression during pathogen-host interaction in mammalian infection caused by C. violaceum. Thus, we propo…
Gene expression can be modulated by transcription factors, which act directly as intracellular signal sensors or via signaling transduction pathways from the external environment. MarR family transcription factors, found in Bacteria and Archaea, act as direct sensors for different signals, controlling virulence, response to oxidative stress, antibiotic resistance and catabolic pathways. A…
Oxidative stress, caused by increased levels of superoxide anion (O2-*), hydrogen peroxide (H2O2), or the hydroxyl radical (OH *), can lead to damage in all cellular components. Several enzymes are responsible for removing these reactive species from the cell, and are activated in response to oxidative stress and to other that trigger this situation, such as high concentrations of iron. …
