Many bacteria form biofilms and survive in the actual environment. Biofilms are not only a major form of bacteria but are also involved in tolerance to environmental stresses and antibiotics, suggesting the association with bacterial pathogenesis. Cells within biofilms display phenotypic heterogeneity; thus, even bacteria, unicellular organisms, can functionally differentiate and show multicellular behavior. Therefore, it is necessary to understand bacteria as a population to control their survival and pathogenesis in the actual environment. Previously, we found that Clostridium perfringens, an anaerobic pathogenic bacterium, form different structures in different temperatures and phenotypic heterogeneity on biofilm matrix gene expression within the biofilm. In this article, I summarize the results of our research on biofilms and their heterogeneity, the mechanisms of post-transcriptional gene expression regulation of virulence genes, and bacteria-host interactions mediated by extracellular membrane vesicles.

She is currently an Innovation Policy Officer in the unit responsible for Research and Innovation in the field of agriculture and rural development. The mission of this Unit is to link research policy and the rural development policy to bridge the gap between science and practice based on the interactive innovation model, notably through the European Innovation Partnership for agricultural productivity and sustainability. The unit is also responsible for parts of Societal Challenge 2 of Horizon 2020.
