Title: “Microbial Facebook: Probing bacterial social interactions during polymicrobial infection”
Abstract
The survival of pathogens in the human body has
been rigorously studied for well over a century. Bacteria are able to colonize,
persist and thrive in vivo due to an
array of capabilities, including the ability to attach to host tissues, produce
extracellular virulence factors, and evade the immune system. Most bacterial
pathogenesis studies have focused on mono-culture infections; however, it is
clear that many bacterial infections are not simply the result of colonization
with a single species, but rather ensue from the actions of polymicrobial
communities. Microbeswithin
polymicrobial infections often display synergistic interactions that result in
enhanced colonization and persistence in the infection site, although the
molecular processes controlling these synergistic interactions are generally
not known. Here, I will discuss how
interactions between biofilm bacteria impact community development, resistance
to host innate immunity, and in vivo
persistence. I will also discuss the use of novel
technologies for probing bacterial interactions in small biofilm populations.
