A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

About

SMELLING BACTERIA.rodentsBacteria produce hundreds of volatile compounds, important for the crafting of microbe-based foods like wine, beer, or cheese. Although  the odorant chemicals emitted by bacteria were rarely characterized in the context of bacteria-bacteria or bacteria-host interactions,  compelling evidence support the notion that bacteria produce unique volatile traces that can act as info chemicals  and mediate several biological functions. In this project, we investigate whether microbe-derived volatile chemicals trigger specific behavioral responses in rodents. The strength of attractiveness and repulsivity will be assessed for volatile chemicals originated from precise bacterial species and single compound will be identified using mass spectrometry coupled with Gas chromatography. This study aims at demonstrating that bacterial-emitted chemicals represent signaling that goes beyond intra-species communication.
