Downstream migration of female silver eel Anguilla anguilla (L.) was studied by remote telemetry in the lower part of the River Meuse (Belgium and The Netherlands) using a combination of 9 detection stations and manual tracking. N=31 eels (LT 64-90cm) were implanted with active transponders and released in 2007 into the River Berwijn, a small Belgian tributary of the River Meuse, 326 km from the North Sea. From August 2007 till April 2008 13 eels (42%) started their downstream migration and were detected at two or more stations. Mean migration speed was 0.62 m.s-1 (or 53 km.day-1). Only two eels (15%) arrived at the North Sea, the others being held up or killed at hydroelectric power stations, caught by fishermen or by predators or stopped their migration and settled in the river delta. A majority (58%) of the eels classified as potential migrants did not start their migration and settled in the River Berwijn or upper Meuse as verified by additional manual tracking. [less ▲]

Fusing recombinant proteins to highly soluble partners is frequently used to prevent aggregation of recombinant proteins in Escherichia coli. Moreover, co-overexpression of prokaryotic chaperones can increase the amount of properly folded recombinant proteins. To understand the solubility enhancement of fusion proteins, we designed two recombinant proteins composed of uncoupling protein 1 (UCP1), a mitochondrial membrane protein, in fusion with MBP or NusA. We were able to express soluble forms of MBP-UCP1 and NusA-UCP1 despite the high hydrophobicity of UCP1. Furthermore, the yield of soluble fusion proteins depended on co-overexpression of GroEL that catalyzes folding of polypeptides. MBP-UCP1 was expressed in the form of a non-covalent complex with GroEL. MBP-UCP1/GroEL was purified and characterized by dynamic light scattering, gel filtration, and electron microscopy. Our findings suggest that MBP and NusA act as solubilizing agents by forcing the recombinant protein to pass through the bacterial chaperone pathway in the context of fusion protein. [less ▲]

Certains Escherichia coli producteurs de Shigatoxines (STEC) sont responsables de toxi-infections d’origine alimentaire qui se traduisent par des diarrhées mais aussi par des syndromes plus graves pour l’homme comme le syndrome hémolytique urémique pouvant provoquer la mort. Il s’agit d’agents zoonotiques dont le réservoir principal est le bovin et les autres ruminants. Les principaux modes de transmission des infections à STEC à l’homme sont la consommation d’aliments contaminés (viande de boeuf peu cuite, produits laitiers non pasteurisés), la transmission de personne à personne, l’ingestion d’eau contaminée et le contact avec des animaux (notamment les bovins) et leur environnement. Les facteurs de virulence des Escherichia coli producteurs de Shigatoxines sont principalement les protéines codées par un îlot de pathogénicité, « Locus of Enterocyte Effacement », impliquées dans la formation de la lésion d’attachement et d’effacement et de la diarrhée et les toxines de Shiga codées par des bactériophages et impliquées dans les syndromes extraintestinaux. La souche de STEC du sérotype O157:H7 est responsable d’épidémies dans le monde causant des milliers de malades et des dizaines de morts. De nombreuses méthodes de diagnostic ont été développées pour identifier ce pathogène à partir des aliments. Elles regroupent des méthodes de bactériologie classique, des méthodes immunologiques et des méthodes moléculaires. Des mesures d’hygiène sont particulièrement importantes pour éviter la contamination des animaux à la ferme et celle de la viande à l’abattoir. Enfin, des modèles d’évaluation du risque ont été développés notamment afin de modéliser le comportement des STEC dans l’aliment. [less ▲]

Escherichia coli was described in 1885 by a German pediatrician, Theodor Escherich, in the faeces of a child suffering diarrhoea. In 1893, a Danish veterinarian postulated that the E. coli species comprises different strains, some being pathogens, others not. Today the E. coli species is subdivided into several pathogenic strains causing different intestinal, urinary tract or internal infections and pathologies, in animal species and in humans. Since this congress topic is the interaction between E. coli and the mucosal immune system, the purpose of this manuscript is to present different classes of adhesins (fimbrial adhesins, afimbrial adhesins and outer membrane proteins), the type 3 secretion system, and some toxins (oligopeptide, AB, and RTX pore-forming toxins) produced by E. coli, that can directly interact with the epithelial cells of the intestinal, respiratory and urinary tracts.

A 1.77 m high piano key weir in operation on the Escouloubre balance basin enabled the observation of real size flows for discharges ranging from 1.2 to 10 m³/s, corresponding to upstream heads ranging from 11 to 48 cm. These observations are depicted and compared to the results gained on three physical models of the weir, built and operated considering a Froude similitude and geometric scale factors of, respectively, 1:7, 1:15 and 1:25. The study highlights the scale effects which may affect piano key weirs scale model studies and provides criteria to limit them. In particular, the results analysis shows that the scale models succeed in representing the flow conditions on the weir when the model upstream head is higher than 60 mm, and succeed in predicting the weir discharge capacity when the model upstream head is higher than 30 mm.
