Mass Spectrometry Methods for Bacterial Infection Diagnosis and Cancer Analysis

Yingdi Zhu

Matrix-assisted laser desorption/ionisation (MALDI) time-of-flight (TOF) mass spectrometry is an important analytical tool in chemistry and biology. Bearing the advantages of easy-to-use, fast measurements and relatively simple data interpretation, MALDI-T ...

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

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

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. ...

Male-killing toxin in a bacterial symbiont of Drosophila

Bruno Lemaitre, Toshiyuki Harumoto

Several lineages of symbiotic bacteria in insects selfishly manipulate host reproduction to spread in a population 1 , often by distorting host sex ratios. Spiroplasma poulsonii2,3 is a helical and motile, Gram-positive symbiotic bacterium that resides in ...

The double-edged toxins : how Spiroplasma Ribosome-Inactivating Proteins affect Drosophila melanogaster life history traits

Mario Gonzalo Garcia Arraez

Many insect species are associated with endosymbiotic bacteria which have the particularity of living within host tissues. Endosymbionts benefit from this stable and nutritious environment, while providing ecological advantages to their host, such as prote ...

In Vitro Culture of the Insect Endosymbiont Spiroplasma poulsonii Highlights Bacterial Genes Involved in Host-Symbiont Interaction

Bruno Lemaitre, Fanny Schüpfer, Mario Gonzalo Garcia Arraez, Florent François Masson

Endosymbiotic bacteria associated with eukaryotic hosts are omnipresent in nature, particularly in insects. Studying the bacterial side of host-symbiont interactions is, however, often limited by the unculturability and genetic intractability of the symbio ...

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 ...

Analysis of cellular and drug action mechanisms in the malaria parasites using systems biology approaches

Anush Chiappino-Pepe

Malaria puts at risk of infection half of the world population and still kills around half a million people every year. The rapid and worrisome rise of drug-resistant malaria parasites hinders the treatment of malaria and calls for a global collaboration t ...

Signatures of selection and environmental adaptation across the goat genome post-domestication

Stéphane Joost, Estelle Rochat

Background: Since goat was domesticated 10,000 years ago, many factors have contributed to the differentiation of goat breeds and these are classified mainly into two types: (i) adaptation to different breeding systems and/or purposes and (ii) adaptation t ...

Dielectrophoresis as a single cell characterization method for bacteria

Philippe Renaud, Thomas Michael Braschler, John McKinney, Neeraj Dhar, Ana Valero

Real-time, quantitative characterization of cells at single-cell resolution, particularly while maintain- ing their intrinsic properties and without affecting cellular processes, is of primary importance in modern biological assays. Dielectrophoresis is a ...

Nanotools and molecular techniques to rapidly identify and fight bacterial infections

Sandor Kasas, Giovanni Longo

Reducing the emergence and spread of antibiotic-resistant bacteria is one of the major healthcare issues of our century. In addition to the increased mortality, infections caused by multi-resistant bacteria drastically enhance the healthcare costs, mainly ...

Functional Characterization of Nucleoid Associated Proteins Acting as Global Transcription Factors in Mycobacterium tuberculosis

Nina Theres Odermatt

The fatal lung disease tuberculosis is caused by the airborne Mycobacterium tuberculosis, a versatile pathogen adapted to rapidly changing environments. Instead of being eradicated by phagocytic cells of its human host, bacilli tune macrophages to support ...

Visualizing chemical transport from extracellular symbionts into squid host tissues using NanoSIMS

Stéphanie Kéren Cohen

Chemical communication is the basis of host-microbe interaction. Insights into this communication will provide a deeper understanding of the mechanisms that govern these complex associations, in beneficial as well as pathogenic contexts. In this dissertati ...
