Foodborne outbreaks associated with consumption of dairy products and processed meat have been known in the past. Infected mother may present with flu-like symptoms, and premature labor and still births are known to occur in perinatal listeriosis. Neonates may ...

In an antibacterial cosmid clone, YS92B, a single gene nasYPL was responsible for the production of the Nas. nasYPL was 903 bp long, and the deduced amino acid sequence showed the highest 71% identity with...

Compared with naïve T cells, memory CD8+ T cells have a transcriptional landscape and proteome that are optimized to generate a more rapid and robust response to secondary infection. Additionally, rewired kinase signal transduction pathways likely contribute to the superior recall response of memory CD8+ T cells, but this idea has not been experimentally confirmed. Herein, we utilized an MS approach to identify proteins that are phosphorylated on tyrosine residues in response to Listeria-induced T-cell receptor (TCR) stimulation in both naïve and memory CD8+ T cells from mice and separated by fluorescence- and fl...

Elisabeth Sauer-Eriksson, José Vázquez-BolandSummaryTo optimize fitness, pathogens selectively activate their virulence program upon host entry. Here, we report that the facultative intracellular bacterium Listeria monocytogenes exploits exogenous oligopeptides, a ubiquitous organic N source, to sense the environment and control the activity of its virulence transcriptional activator, PrfA. Using a genetic screen in adsorbent-treated ...

Niemira, Olasunkanmi AyeniAbstractPeriodic outbreaks of foodborne pathogens have resulted in food safety concerns, due to health implications and cost consequences. Occurrence of Listeria monocytogenes in foods and listeriosis have been reported in developed countries; however, documentation of listeriosis in South Africa is limited. In 2017–2018, Listeria was reported on polony (processed deli meat) and listeriosis was observed...

hramm M Abstract A major function of macrophages during infection is initiation of the proinflammatory response, leading to the secretion of cytokines that help to orchestrate the immune response. Here, we identify reactive oxygen species (ROS) as crucial mediators of proinflammatory signaling leading to cytokine secretion in Listeria monocytogenes-infected macrophages. ROS produced by NADPH oxidases (Noxes), such as Nox2, are key components of the macrophage response to invading pathogens; however, our data show that the ROS that mediated proinflammatory signaling were produced by mitochondria (mtROS). We identif...
