Bacterial matrix metalloproteases and serine proteases contribute to the extra-host inactivation of enteroviruses in lake water

Enteroviruses are ubiquitous contaminants of surface waters, yet their fate in presence of microbial congeners is poorly understood. In this work, we investigated the inactivation of Echovirus-11 (E11) and Coxsackievirus-A9 (CVA9) by bacteria isolated from ...

Do chance encounters between heterogeneous cells shape the outcome of tuberculosis infections?

John McKinney, Ophélie Rutschmann, Chiara Toniolo

The sum of all of the interactions between single bacteria and host cells determines if an infection is cleared, controlled, or progresses at the whole host-organism level. These individual interactions have independent trajectories defined by diverse and ...

Indication of spatially random occurrence of Chlamydia-like organisms in Bufo bufo tadpoles from ponds located in the Geneva metropolitan area

Séverine Vuilleumier Varisco, Stéphane Joost, Oliver Michele Selmoni, Elia Vajana, Ivo Widmer

Occurrence of bacteria belonging to the order Chlamydiales was investigated for the first time in common toad (Bufo bufo) tadpole populations collected from 41 ponds in the Geneva metropolitan area, Switzerland. A Chlamydiales-specific real-time PCR was us ...

A modeling approach integrating microbial activity, mass transfer, and geochemical processes to interpret biological assays: An example for PCE degradation in a multi-phase batch setup

Christof Holliger, Julien Maillard, Alexandra Marie Murray

The rate at which organic contaminants can be degraded in aquatic environments is not only dependent upon specific degrading bacteria, but also upon the composition of the microbial community, mass transfer of the contaminant, and abiotic processes that oc ...

Bacterial traps and advances in nanobiotechnology for atomic force microscopy

Oliver Peric

The atomic force microscope (AFM) allows the analysis of living microorganisms in physiological conditions on the nanometer scale. The observation of bacteria in physiological aqueous medium necessitates a robust immobilization of the bacterium to the surf ...

Gram-type differentiation of bacteria with 2D hollow photonic crystal cavities

Romuald Houdré, Rita Therisod, El Hadji Malick Camara

Fast and label-free techniques to analyze viruses and bacteria are of crucial interest in biological and bio-medical applications. For this purpose, optofluidic systems based on the integration of photonic structures with microfluidic layers were shown to ...

Modularity and determinants of a (bi-)polarization control system from free-living and obligate intracellular bacteria

Suliana Manley, Seamus John Holden

Although free-living and obligate intracellular bacteria are both polarized it is unclear whether the underlying polarization mechanisms and effector proteins are conserved. Here we dissect at the cytological, functional and structural level a conserved po ...

Sensing Gram-negative bacteria: a phylogenetic perspective

Bruno Lemaitre

Gram-negative bacteria represent a major group of pathogens that infect all eukaryotes from plants to mammals. Gram-negative microbe-associated molecular patterns include lipopolysaccharides and peptidoglycans, major immunostimulatory determinants across p ...
