Influence of bacterial swimming and hydrodynamics on infection by phages

This study investigates how bacterial swimming and fluid flows affect phage infection rates, finding hydrodynamic interactions enhance infection at flagella while suppressing it at the cell body.

Interplay between environmental yielding and dynamic forcing regulates bacterial growth

This study shows that bacterial growth in rheologically complex environments is regulated by the balance between environmental yield stress and external forcing.

Interfacial morphodynamics of proliferating microbial communities

The paper develops a continuum model to study interfacial morphodynamics in microbial communities, finding that interface stability depends on cell proliferation rates and substrate friction.

Pattern formation by bacteria-phage interactions

This study develops a theoretical model of bacteria-phage interactions showing how non-reciprocal predator-prey dynamics lead to complex spatial patterns in bacterial and phage organization.

Roughening instability of growing 3D bacterial colonies

This study shows that 3D bacterial colonies develop a rough, branched morphology due to nutrient limitations, differing from 2D colonies.

Chemotactic Migration of Bacteria in Porous Media

This study examines how Escherichia coli migrates in 3D porous media, finding that confinement changes chemotactic mechanisms and population dynamics, requiring modified motility parameters in continuum models.

High-molecular-weight polymers from dietary fiber drive aggregation of particulates in the murine small intestine

This study shows that high-molecular-weight dietary fiber polymers drive aggregation of particulates in the murine small intestine, independent of mucins and immunoglobulins.
