Proteus Mirabilis Swarm-colony Development with Drift
Proteus mirabilis is a bacterium that is widely distributed in soil and water in the natural environment. It is also found in the intestinal tract of many mammals, including human. Broth cultures of Proteus mirabilis consist of small swimmer cells, but produce a morphologically and physiologically distinct cell type, called swarmer cells, when inoculated on a solid surface. This process is refe...
متن کاملA structured-population model of Proteus mirabilis swarm-colony development.
In this paper we present continuous age- and space-structured models and numerical computations of Proteus mirabilis swarm-colony development. We base the mathematical representation of the cell-cycle dynamics of Proteus mirabilis on those developed by Esipov and Shapiro, which are the best understood aspects of the system, and we make minimum assumptions about less-understood mechanisms, such ...
متن کاملPeriodic phenomena in Proteus mirabilis swarm colony development.
Proteus mirabilis colonies exhibit striking geometric regularity. Basic microbiological methods and imaging techniques were used to measure periodic macroscopic events in swarm colony morphogenesis. We distinguished three initial phases (lag phase, first swarming phase, and first consolidation phase) followed by repeating cycles of subsequent swarming plus consolidation phases. Each Proteus swa...
متن کاملModeling the role of the cell cycle in regulating Proteus mirabilis swarm-colony development
We present models and computational results which indicate that the spatial and temporal regularity seen in Proteus mirabilis swarm-colony development is largely an expression of a sharp age of dedifferentiation in the cell cycle from motile swarmer cells to immotile dividing cells (also called swimmer or vegetative cells.) This contrasts strongly with reaction-diffusion models of Proteus behav...
متن کاملOn an age and spatially structured population model for Proteus Mirabilis swarm-colony development
Proteus mirabilis are bacteria that make strikingly regular spatial-temporal patterns on agar surfaces. In this paper we investigate a mathematical model that has been shown to display these structures when solved numerically. The model consists of an ordinary differential equation coupled with a partial differential equation involving a first-order hyperbolic aging term together with nonlinear...
