Bacterial extracellular polymers and flocculation of activated sludges
… produced by bacteria play an important role in bacterial aggregation or bacterial flocculation in secondary waste treatment. The mechanisms responsible for this floc formation are thought to be polymer induced adsorption and interparticle bridging among bacterial cells or between bacterial cells …

Cha-Cha-Cha: Variable Adhesive Activity of the <italic>Haemophilus</Italic> Cryptic Genospecies Trimeric Autotransporter Cha
… that the C-terminus of Cha trimerizes in the bacterial outer membrane and is capable presenting a heterologous passenger domain (Hia) in a functional form, thus confirming that Cha is a trimeric autotransporter. Southern analysis revealed that <italic>cha</italic> is unique to the …

Higher-order interaction inhibits bacterial invasion of a phototroph-predator microbial community
… of this interaction is the algal inhibition of bacterial aggregation which leaves bacteria vulnerable to ciliate predation. This mechanism requires both the algae and the ciliate to be present and provides an example of invasion resistance through a trait-mediated higher-order interaction. In a …

Modification and Translocation of the Biofilm Exopolysaccharide Poly-β(1,6)-N-acetyl-D-glucosamine
… and have been shown to play an important role in bacterial aggregation, surface attachment, and serve as a protective barrier against antibiotics and host defenses. A key exopolysaccharide required for biofilm formation by a number of pathogenic bacteria is poly-beta(1,6)-N-acetyl-D-glucosamine …

A Novel Antibiofilm Treatment for Surgical Site Infections
… drug Disulfiram, previously showed antibacterial activity against mycobacteria and streptococci in combination with copper ions (Cu2+) but had not been investigated against S. aureus and S. epidermidis biofilms. In this thesis, the antibacterial and antibiofilm activities of DDC- with …

Design and Evaluation of Nanoparticle Systems for Bacterial Targeting
… with the diverse and complex structures of bacterial surfaces remain poorly understood, limiting their progress toward clinical translation. Thus, this thesis investigates the design of two NP systems: 1) cationic fusogenic liposomes (cFLs) and 2) metal-organic frameworks (MOFs) for …

Surface proteins of Finegoldia magna interacting with the human host
… the antimicrobial peptide LL-37 and the antibacterial chemokine MIG/CXCL9. Furthermore, the protease cleaves fibrinogen and thereby inhibits fibrin network formation. To our knowledge, the first example of directed mutagenesis of F. magna is presented with the disruption of the sufA gene. The …
