Thermal Stress Interacts With Surgeonfish Feces to Increase Coral Susceptibility to Dysbiosis and Reduce Tissue Regeneration

Dysbiosis of coral microbiomes results from various biotic and environmental stressors, including interactions with important reef fishes which may act as vectors of opportunistic microbes via deposition of fecal material. Additionally, elevated sea surfac ...

Participatory research to monitor lake water pollution

Luc Patiny, Carlos Vivar Rios, Rachel Aronoff

A participatory research team, concerned about water quality around Lake Geneva, particularly in the Montreux Bay region where some were lifeguards, ran sampling campaigns to determine summertime levels of lake water pollution. The participants were brough ...

Infection with a small intestinal helminth, Heligmosomoides polygyrus bakeri, consistently alters microbial communities throughout the murine small and large intestine

Nicola Harris, Benjamin John Marsland, Mario Michael Zaiss, Alexis Rapin, Luc Xavier Marie Lebon, Audrey Geneviève Chuat

Increasing evidence suggests that intestinal helminth infection can alter intestinal microbial communities with important impacts on the mammalian host. However, all of the studies to date utilize different techniques to study the microbiome and access dif ...

Overlapping and essential roles for molecular and mechanical mechanisms in mycobacterial cell division

Georg Fantner, John McKinney, Adrian Pascal Nievergelt, Pascal Damian Odermatt, Haig Alexander Eskandarian, Mélanie Thérèse Marie Hannebelle

Mechanisms to control cell division are essential for cell proliferation and survival. Bacterial cell growth and division require the coordinated activity of peptidoglycan synthases and hydrolytic enzymes to maintain mechanical integrity of the cell wall. ...

Differential presentation of a single antimicrobial peptide is sufficient to identify LPS from distinct bacterial samples

Timothy Matthias Reichart

Rapid detection and identification of bacteria is important for human health, biodefense, and food safety. Small arrays of different antimicrobial peptides (AMPs) enable the identification of lipopolysaccharide (LPS) samples from a variety of bacterial spe ...

High amounts of antibiotic resistance genes and Class I integrons are disseminated in rivers of the Mekong delta (Viet Nam) from the effluents of intensive shrimp farms

Pierre Rossi, Florian Frédéric Vincent Breider, Emmanuelle Rohrbach

In the Mekong delta, intensive shrimp farming rely heavily on a wide panel of antibiotics (ABs) to prevent disease epidemics. Consequently, large amounts of antibiotic multi-resistant bacteria are emerging, threatening adjacent aquatic habitats used for ir ...

Atomic Force Microscopy of Biological Systems: Quantitative Imaging and Nanomotion Detection

Petar Stupar

The core of this thesis is the application of different modalities of atomic force microscopy to study living systems. After a brief introduction, quantitative imaging state of the art is presented and the applications for mammalian, plant, bacterial, and ...

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 ...

Common and unique strategies of male killing evolved in two distinct Drosophila symbionts

Bruno Lemaitre, Toshiyuki Harumoto

Male killing is a selfish reproductive manipulation caused by symbiotic bacteria, where male offspring of infected hosts are selectively killed. The underlying mechanisms and the process of their evolution are of great interest not only in terms of fundame ...

Behaviour of carbon-14 containing low molecular weight organic compounds in contaminated groundwater under aerobic conditions

Aislinn Ann Boylan

Short chain carbon-14 (C-14) containing organic compounds can be formed by abiotic oxidation of carbides and impurities within nuclear fuel cladding. During fuel reprocessing and subsequent waste storage there is potential for these organic compounds to en ...
