Bacterial collectives
The natural world is full of bacterial collectives, ranging from transient aggregations to highly integrated groups. These structures can display multicellular‑like features but typically do not reproduce as groups, and thus are not units of selection in a paradigmatic Lewontin-sense. In the …

Engineering bacterial magnetic nanoparticles
Magnetosomes, produced by magnetotactic bacteria (MTB), are the most attractive alternative source of non-toxic biocompatible magnetic nanoparticles (MNPs). A magnetosome contains Fe2O4 magnetite with properties superior to MNPs synthesized by the traditional chemical route. However, synthesis of …

Bacterial resistance to chemotherapy
The last decade has witnessed an unprecedented development in the therapy of infectious diseases and a significant change in the practice of medicine. The variety of antibiotic substances discovered and made freely available during this short space of time permitted the ready control of many …

Structurally coloured bacterial colonies
… uncovered that structural colouration in some bacterial colonies stems from the organisation of the cells into two-dimensional photonic crystals, but it is still unknown how the arrangement of the cells within the polycrystalline structure can affect the colony's appearance. Moreover, the …

Microfluidics for bacterial chemotaxis
Bacterial chemotaxis, a remarkable behavioral trait which allows bacteria to sense and respond to chemical gradients in the environment, has implications in a broad range of fields including but not limited to disease pathogenesis, in-situ bioremediation and marine biogeochemistry. And therefore, …

Elucidating the Secreted Bacterial Kinome
Pages vi-x are misnumbered as pages v-ix.

Innate memory to bacterial infection
… markers analysis, cell depletion, heat killed bacterial immunisation and bacterial infection.<br/><br/>This study hypothesised that following immunisation mice would be able to restrain bacterial growth and aimed to investigate the magnitude and longevity and specificity of the response. …

Population dynamics of bacterial persistence
… differently under identical environments. Bacterial persistence is a prime example of such phenotypic heterogeneity, whereby a population survives under an antibiotic attack, by keeping a fraction of population in a drug tolerant state, the persister state. Specifically, persister cells …

Signal Processing in Bacterial Chemotaxis
… in the signal transduction pathway of bacterial chemotaxis and 2) the point of convergence of the methylation-independent systems of chemotaxis with the methylation-dependent system. The site of ATP utilization was localized at the CheY protein/switch point. In an Eaeheriehia call …

Integrated modeling of bacterial metabolism
… to achieve a system-level understanding of bacterial metabolism. Despite previous models have yielded insightful results, most of them focus on specific subsystems and endeavors to build highly integrated computational models are still rare. Here, I present my work towards developing and …

Ecological insights from bacterial networks
… In this work I explore the nature of these bacterial networks, using computational tools to uncover ecological associations with relevance to both human health and environmental restoration. I begin with the discovery of a massive, global network of recent gene exchange linking even …

Tactic behaviors in bacterial dynamics
… media. Physical descriptions are developed for bacterial chemotaxis (response to chemical agents) near particles exuding attractants, a small-scale process with global-scale implications for the biogeochemistry of the oceans. Three cases were investigated: a stationary particle, a slowly moving …
