High-resolution imaging and analysis of the intestinal bacterial load of Caenorhabditis elegans during early adulthood

We study the presence within the worm Caenorhabditis elegans (C. elegans) of a fluorescent strain of the worm's bacterial food (Escherichia coli (E. coli) OP50) during early adulthood. Use of a microfluidic chip based on a thin glass coverslip substrate al ...

Mechanism ofcyclic beta-glucan export by ABC transporter Cgt of Brucella

Henning Paul-Julius Stahlberg, Dongchun Ni, Na Wu

Polysaccharides play critical roles in bacteria, including the formation of protective capsules and biofilms and establishing specific host cell interactions. Their transport across membranes is often mediated by ATP-binding cassette (ABC) transporters, wh ...

The molecular treasure box of environmental Vibrio cholerae strains

Natalia Carolina Drebes Dorr

Cholera pandemics have been affecting humankind for centuries and are still considered a major public health problem, especially in regions around the world with poor access to clean water and sanitation. Cholera pandemics are caused by a specific lineage ...

Comparison of chitin‐induced natural transformation in pandemic Vibrio cholerae O1 El Tor strains

Melanie Blokesch, Sandrine Stutzmann

The human pathogen Vibrio cholerae serves as a model organism for many important processes ranging from pathogenesis to natural transformation, which has been extensively studied in this bacterium. Previous work has deciphered important regulatory circuits ...

Mammalian membrane trafficking as seen through the lens of bacterial toxins

Françoise Gisou van der Goot Grunberg, Francisco De Magalhães Sarmento R De Mesquita, Oksana Andrei Sergeeva

A fundamental question of eukaryotic cell biology is how membrane organelles are organised and interact with each other. Cell biologists address these questions by characterising the structural features of membrane compartments and the mechanisms that coor ...

Intracellular bacteria engage a STING-TBK1-MVB12b pathway to enable paracrine cGAS-STING signalling

Andrea Ablasser, Thomas Charles Henry Rossi, Bing Zhang, Alix Martin, Ensieh Farahani

The innate immune system is crucial for eventual control of infections, but may also contribute to pathology. Listeria monocytogenes is an intracellular Gram-positive bacteria and a major cause of food-borne disease. However, important knowledge on the int ...

Vibrio cholerae filamentation promotes chitin surface attachment at the expense of competition in biofilms

Alexandre Louis André Persat

Collective behavior in spatially structured groups, or biofilms, is the norm among microbes in their natural environments. Though biofilm formation has been studied for decades, tracing the mechanistic and ecological links between individual cell morpholog ...

Characterization of Efficiency and Mechanisms of Cold Atmospheric Pressure Plasma Decontamination of Seeds for Sprout Production

Alexandra Waskow

The consumption of fresh fruit and vegetable products has strongly increased during the past few decades. However, inherent to all minimally processed products is the short shelf life, and the risk of foodborne diseases, which have been increasingly relate ...

Genotyping Of Bacillus Spp. Isolate Collection From Natural Samples

The aim of this study was genotyping and identification of collection of 164 Bacillus spp. isolates, from samples of soil, manure, and straw gathered from across Serbia, using Pulse field gel electrophoresis (PFGE) combined with sequencing of tuf gene, one ...

The dual oxidase gene BdDuox regulates the intestinal bacterial community homeostasis of Bactrocera dorsalis

Bruno Lemaitre

The guts of metazoans are in permanent contact with the microbial realm that includes beneficial symbionts, nonsymbionts, food-borne microbes and life-threatening pathogens. However, little is known concerning how host immunity affects gut bacterial commun ...

Gut physiology mediates a trade-off between adaptation to malnutrition and susceptibility to food-borne pathogens

Bruno Lemaitre, Sveta Chakrabarti, Sylvain Kolly

The animal gut plays a central role in tackling two common ecological challenges, nutrient shortage and food-borne parasites, the former by efficient digestion and nutrient absorption, the latter by acting as an immune organ and a barrier. It remains unkno ...

Solar disinfection of wild Salmonella sp. in natural water with a 18 L CPC photoreactor: Detrimental effect of non-sterile storage of treated water

César Pulgarin, Julian Andrés Rengifo Herrera, Frédéric Sciacca

For the first time solar disinfection of liters of water containing wild Salmonella sp. and total coliforms was carried out in a compound parabolic collector (CPC) photoreactor at temperatures of almost 50 degrees C. Using surface water with high turbidity ...

Dramatic enhancement of solar disinfection (SODIS) of wild Salmonella sp in PET bottles by H2O2 addition on natural water of Burkina Faso containing dissolved iron

César Pulgarin, Julian Andrés Rengifo Herrera, Frédéric Sciacca

Disinfection of surface water containing dissolved iron (0.3 mg L-1) at natural neutral pH (similar to 7.5) was carried out via solar disinfection (SODIS) treatment in PET bottles with H2O2 (10 mg L-1). Wild coliforms and Salmonella sp. were monitored for ...

Interdigitated electrode DNA biosensor for detection of food-borne pathogens by impedance spectroscopy

Daniel Berdat

The commercial application of biosensors has had a significant impact in a number of areas, particularly in the field of medical diagnostics. But in spite of the great number of publications, only a few systems are commercially available in food analysis. ...
