Energy-harnessing problem solving of primordial life: Modeling the emergence of catalytic host-nested parasite life cycles

All life forms on earth ultimately descended from a primordial population dubbed the last universal common ancestor or LUCA via Darwinian evolution. Extant living systems share two salient functional features, a metabolism extracting and transforming energ ...

More than seven decades of Acta Tropica: Looking back to move into the future

Akuto Akpedze Konou, Jürg Utzinger

Acta Tropica is an international, peer-reviewed journal advancing scientific research in the fields of tropical medicine and parasitology. This article elucidates the rich history of the journal and speculates about its future. Acta Tropica was launched in ...

Intracellular competition for nitrogen controls dinoflagellate population density in corals

Anders Meibom, Stéphane Laurent Escrig, Thomas Krüger, Maoz Fine, Julia Marie Jeanne Yvonne Bodin, Maria-Evangelia Giovani

The density of dinoflagellate microalgae in the tissue of symbiotic corals is an important determinant for health and productivity of the coral animal. Yet, the specific mechanism for their regulation and the consequence for coral nutrition are insufficien ...

Virus-Mediated Cell-Cell Fusion

Lucie Josepha Marie Bracq

Cell-cell fusion between eukaryotic cells is a general process involved in many physiological and pathological conditions, including infections by bacteria, parasites, and viruses. As obligate intracellular pathogens, viruses use intracellular machineries ...

Hydrology and density feedbacks control the ecology of intermediate hosts of schistosomiasis across habitats in seasonal climates

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Natalie Claire Ceperley, Theophile Mande, Francisco Javier Perez Saez, Marino Gatto

We report about field and theoretical studies on the ecology of the aquatic snails (Bulinus spp. and Biomphalaria pfeifferi) that serve as obligate intermediate hosts in the complex life cycle of the parasites causing human schistosomiasis. Snail abundance ...

Genetic diversity of two Daphnia-infecting microsporidian parasites, based on sequence variation in the internal transcribed spacer region

Stefan Jean Laurent

Background: Microsporidia are spore-forming obligate intracellular parasites that include both emerging pathogens and economically important disease agents. However, little is known about the genetic diversity of microsporidia. Here, we investigated patter ...

Understanding the role of antibodies in murine infections with Heligmosomoides (polygyrus) bakeri: 35 years ago, now and 35 years ahead

Nicola Harris

The rodent intestinal nematode H.p.bakeri has played an important role in the exploration of the host–parasite relationship of chronic nematode infections for over six decades, since the parasite was first isolated in the 1950s by Ehrenford. It soon became ...

Functional genomics of Plasmodium falciparum using metabolic modelling and analysis

Vassily Hatzimanikatis, Stepan Tymoshenko, Rebecca Oppenheim, Dominique Soldati-Favre

Plasmodium falciparum is an obligate intracellular parasite and the leading cause of severe malaria responsible for tremendous morbidity and mortality particularly in sub-Saharan Africa. Successful completion of the P. falciparum genome sequencing project ...

Loss of reproductive parasitism following transfer of male-killing Wolbachia to Drosophila melanogaster and Drosophila simulans

Wolbachia manipulate insect host biology through a variety of means that result in increased production of infected females, enhancing its own transmission. A Wolbachia strain (wInn) naturally infecting Drosophila innubila induces male killing, while nativ ...

Malaria parasites form filamentous cell-to-cell connections during reproduction in the mosquito midgut

Physical contact is important for the interaction between animal cells, but it can represent a major challenge for protists like malaria parasites. Recently, novel filamentous cell-cell contacts have been identified in different types of eukaryotic cells a ...

An essential Aurora-related kinase transiently associates with spindle pole bodies during Plasmodium falciparum erythrocytic schizogony

Aurora kinases compose a family of conserved Ser/Thr protein kinases playing essential roles in eukaryotic cell division. To date, Aurora homologues remain uncharacterized in the protozoan phylum Apicomplexa. In malaria parasites, the characterization of A ...

A miniaturized continuous dielectrophoretic cell sorter and its applications

Philippe Renaud, Thomas Michael Braschler, Nicolas Demierre, Ana Valero

There is great interest in highly sensitive separation methods capable of quickly isolating a particular cell type within a single manipulation step prior to their analysis. We present a cell sorting device based on the opposition of dielectrophoretic forc ...

Continuous-flow separation of cells in a lab-on-a-chip using "liquid electrodes" and multiple-frequency dielectrophoresis

Nicolas Demierre

This thesis reports on the integration of continuous-flow cell separation method for lab-on-a-chip applications. Cell separation methods are widely used in biology to prepare samples prior to analysis. There is a need for a highly sensitive separation meth ...

Label-free detection of Babesia bovis infected red blood cells using impedance spectroscopy on microfabricated flow cytometer

Philippe Renaud, Thomas Michael Braschler, Nicolas Demierre

Impedance spectroscopy is a powerful tool for label-free analysis and characterisation of living cells. In this work, we achieved the detection of Babesia bovis infected red blood cells using impedance spectroscopy on a microfabricated flow cytometer. The ...
