Abstract:

We propose a project to understand better antibiotic resistance, and in particular the diversity of response from individual cells. Using new eperimental methodology (microfluidics and automated imaging) it will be possible to measure at single cell level the physiological and gene expression changes upon exposing bacteria to antibiotics. Single cell imaging is essential to disentangle cell cycle related effects, from other (more interesting to us) forms of heterogeneity in the response. This work builds on an ongoing more general research line, of looking at the physical structure of the bacterial nucleoid, and the role of this in cell physiology.
