Abstract Interactions between parasite, host and host-associated microbiota are increasingly understood as important determinants of disease progression morbidity. Salmon lice, including the parasitic copepod Lepeophtheirus salmonis related species, perhaps most problem facing Atlantic aquaculture after feed sustainability. lice parasitize surface fish, feeding off mucus, scales underlying tissue. Secondary bacterial infections a major source associated In this study we tracked diversity...
The colonization of surfaces by bacterial biofilms constitutes a huge problem in healthcare and industry. When attempting biofilm inactivation or removal, it is crucial to sufficiently wet the surface with antibacterial agents; however, certain efficiently resist wetting, origin this behavior remains date unclear. Here, we demonstrate that, depending on growth medium used, model bacterium Bacillus subtilis can form colonies distinct properties: find either hydrophilic two variants...
Abstract Surface superhydrophobicity makes bacterial biofilms very difficult to fight, and it is a combination of their matrix composition complex surface roughness which synergistically protects these biomaterials from wetting. Although trying eradicate with aqueous (antibiotic) solutions common practice, this can be futile approach if the have superhydrophobic properties. To date, there are not many options available reduce liquid repellency or prevent material property developing. Here,...
Microbial biofilms are tightly packed, heterogeneous structures that serve as arenas for social interactions. Studies on Gram negative models reveal during evolution in structured environments like biofilms, isogenic populations commonly diversify into phenotypically and genetically distinct variants. These variants can settle alternative biofilm niches develop new types of interactions greatly influence population productivity. Here, we explore the evolutionary diversification pellicle...
For the inactivation or removal of bacterial biofilms via chemical physical processes, it is crucial to sufficiently wet biofilm surface. However, many efficiently resist wetting by water, oil even organic solvents. Here, we demonstrate how exposing surface mature colonies concentrated ethanol, saline glucose solutions results in topographical changes that enable their wettability. With this approach, omniphobic become wettable towards aqueous and oils. As a result reduced liquid repellency,...
