Standard virulence evolution theory assumes that virulence factors are maintained because
they aid parasitic exploitation, increasing growth within and/or transmission between hosts …

During stress, bacteria undergo extensive physiological transformations, many of which are
coordinated by ppGpp. Although ppGpp is best known for enhancing cellular resilience by …

This chapter talks about antimicrobial compounds that are divided into two classes:
traditional and naturally occurring. Antimicrobials are classified as traditional when they (i) …

Borrelia burgdorferi, the spirochete that causes Lyme disease, is maintained in nature via an
enzootic cycle that comprises a tick vector and a vertebrate host. Transmission from the tick …

Prodigiosin, a red linear tripyrrole pigment and a member of the prodiginine family, is
normally secreted by the human pathogen Serratia marcescens as a secondary metabolite …

Foodborne bacterial pathogens encounter many environmental insults or stresses during
food production, processing, storage, distribution, and preparation. However, these …

In Enterobacteriaceae, the transcriptional regulator AmpR, a member of the LysR family,
regulates the expression of a chromosomal β-lactamase AmpC. The regulatory repertoire of …

Virulence gene expression in pathogenic bacteria is modulated by environmental
parameters. A key factor in this expression is temperature. Its effect on virulence gene …

The general stress response (GSR) is a widespread strategy developed by bacteria to adapt
and respond to their changing environments. The GSR is induced by one or multiple …

The success of Salmonella as a foodborne pathogen can probably be attributed to two major
features: its remarkable genetic diversity and its extraordinary ability to adapt. Salmonella …
