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

bacterial interactions Although competitive interactions between bacteria (bacterial interference), are likely to represent a key aspect of many infectious processes, the nature of these interactions within mixed biofilm communities is poorly understood. We use in vitro biofilm models to study  adhesion or growth-related bacterial interferences within mixed communities. We identify molecules released by bacteria in mixed biofilm environments contributing to competitive or cooperative behaviors affecting population dynamics.
