Bacteroides thetaiotaomicron metabolic activity decreases with polysaccharide molecular weight

Tom Ian Battin, Alexandre Louis André Persat, Jeremy Pak Hei Wong

The human colon hosts hundreds of commensal bacterial species, many of which ferment complex dietary carbohydrates. To transform these fibers into metabolically accessible compounds, microbes often express a series of dedicated enzymes homologous to the st ...

Fluid flow structures gut microbiota biofilm communities by distributing public goods

Tom Ian Battin, Alexandre Louis André Persat, Jeremy Pak Hei Wong

Bacterial gut commensals experience a biologically and physically complex mucosal environment. While many chemical factors mediate the composition and structure of these microbial communities, less is known about the role of mechanics. Here, we demonstrate ...

The Effects of Spatial Organization and Fluid Flow on the Social Interactions in Microbial Communities

Jeremy Pak Hei Wong

Bacteria often engage in social interactions with neighbouring bacteria. Ecosystems which are subjected to social interactions have been widely studied in well mixed settings such as test tubes, allowing us to identify the cellular components contributing ...

Engineering Agrobacterium tumefaciens Adhesion to Target Cells

Alexandre Louis André Persat, Xavier Jean-Yves Pierrat, Jeremy Pak Hei Wong, Alix Kim Lan Pham

Agrobacterium tumefaciens is a plant pathogen commonly repurposed for genetic modification of crops. Despite its versatility, it remains inefficient at transferring DNA to many hosts, including to animal cells. Like many pathogens, physical contact between ...

The Mammalian Membrane Microenvironment Regulates the Sequential Attachment of Bacteria to Host Cells

Alexandre Louis André Persat, Xavier Jean-Yves Pierrat, Jeremy Pak Hei Wong

Pathogen attachment to host tissue is critical in the progress of many infections. Bacteria use adhesion in vivo to stabilize colonization and subsequently regulate the deployment of contact-dependent virulence traits. To specifically target host cells, th ...

Catechol Containing Polyelectrolyte Complex Nanoparticles as Local Drug Delivery System for Bortezomib at Bone Substitute Materials

Martin Guillermo Mueller, Jeremy Pak Hei Wong

The proteasome inhibitor bortezomib (BZM) is one of the most potent anti-cancer drugs in the therapy of multiple myeloma. In this study, an adhesive drug delivery system (DDS) for BZM was developed. Therefore, we extended the present DDS concept of polyele ...
