Modelling within-Host Spatiotemporal Dynamics of Invasive Bacterial Disease (2008)

Andrew J. Grant, Olivier Restif, Trevelyan J. McKinley, Mark Sheppard, Duncan J. Maskell, Pietro Mastroeni

Mechanistic determinants of bacterial growth, death, and spread within mammalian hosts cannot be fully resolved studying a single bacterial population. They are also currently poorly understood....
