Malignant catarrhal fever (MCF) is an usually lethal pathology which has been described in a large number of ruminant species. Based on the etiology, two main forms of MCF have been described, i.e., the European and the African forms due to ovine herpesvirus 2 (OvHV-2) and alcelaphine herpesvirus 1 (AlHV-1), respectively. The present study was devoted to the African form of MCF (AF-MCF) and to its causative agent AlHV-1. AlHV-1 belongs to the Gammaherpesvirinae subfamily of the Herpesviridae family. Wildebeests (Connochaetes spp) carry AlHV-1, which is lethal for a large number of ruminant species, while apparently harmless to its natural host. Here, we first reproduced AF-MCF using the rabbit as animal model. Macroscopic and microscopic lesions induced by AlHV-1 infection were characteristic of AF-MCF described in cattle. Next, we undertook the cloning of AlHV-1 genome as an bacterial artificial chromosome (BAC). The molecular tools required were produced. They should allow the production of a AlHV-1-BAC shortly. The rabbit animal model together with the BAC technology will allow further studies to address AF-MCF pathogenesis. [less ▲]

In this work, we demonstrated that neonatal cortical progenitors characterized by an expression of a polysialilated form on NCAM (Neural Cell Adhesion Molecule) are able to differentiate into astrocytes or oligodendrocytes. Moreover, those precursors are able of a phenotypic plasticity as they differnetiate into Schwann Cells when grafted into adult demyelinated lesions. [less ▲]

This work is on the analysis of automnal data collected during an intensive two-month bird ringing campaign organized near Liège in 1984. At first we remind the reader of some features and results related tho the study of avian migrations in general, and to the chaffinch Fringilla coelebs in particular. This information, gathered from an abundant literature, is essential to the good understanding of our own results. We then deal with three aspects of the data we collected during the fall migration, 1984. The first one describes the visible migration evolution of the chaffinch, as we watched it on the field as it appears for each age and sex class following the evolution curve of the daily number of catches. Furthermore, we compare these results and relate them to the evolution of the meteorological conditions, which have been logged daily on the capture site. Thus, we ascertain that in 1984 the young birds are passing by before the adults and the females before the males (Chi2) and that for a given wind direction the migration intensity is determined by rainfalls. The second aspect is a biometrical principal components analysis of a group of 426 chaffinches. Besides a strongly marked sexual dimorphism in favour of the males this analysis revealed groups, independently from individual age and sex. These groups differ from each other in biometric characteristics and especially in their period of migratory passage. The groups are obviously more or less overlapping. The results of the first aspect are emphasized in the interpredation of the clusters observed on the diagrams. The interpretation of the separating factors is the speculative nature: the wellknow clinal variations and the more or less pronounced migratory habits of the chaffinch as disclosed in the literature are not sufficient to explain the observed trends. Finally, a plot of the daily weighted averages of the wing shape index (Holynsky, 1965), interpreted according to Rensch (1938) confirms beyond any doubt the differences between successive groups of migrators. We briefly advocate this interesting graphical method in the kind of investigations. However in spite of these stimulating results, we have to conclude that exact determination of the geographic origin of the different observed groups is by now impossible. Some suggestions are presented for the planning of futher studies which might contribute to greater precision. [less ▲]

The predator Episyrphus balteatus (DeGeer) (Diptera, Syrphidae), efficient in the biological control against the aphids is able to perceive most of the volatile compounds from plants and aphids. All these semiochemicals define the different relationships between the three trophic levels (plant-phytophagous-predator) and directly help E. balteatus, as other predators and parasitoids, to locate their prey. In this context, our study highlights the importance of plant and aphid semiochemicals in the foraging behavior of the predator E. balteatus. [less ▲]

Hydrogen is currently considered as to become an important energy carrier and energy resource in the next century. Research and developments are now focusing on a green way to produce the hydrogen. One of these way is the microbial way, which uses microorganisms in anaerobic condition to produce hydrogen and volatile fatty acids in aqueous media. This technology may also work with liquid wastes treatment coming from the food industry. Chimiotrophic bacterias from the genus Clostridium shows many advantages due to the substrates divsersity they can assimilate but also to the production yields they reach. The study of hydrogen production by Colstridium butyricum CWBI sp1009, isolated and characterized in earlier works in the CWBI, is the main purpose of this work. This strain was inoculated in a continuous anaerobic bio reactor with fixed biomass on a rotative horizontal cylinder. This reactor reach a glucose conversion yield of 2.1 mol_hydrogen/mol_glucose consumed. The phenomenas occurring in this reactor need to be completely understood for a future application at an industrial scale. One factor influencing the hydrogen production without being well understood is the hydrogen partial pressure and the retro inhibition it affects upon the organisms. Increasing the hydrogen transfer from the liquid to gas phase in batch fermentation in 200ml of culture media and degassing daily with nitrogen enhance the hydrogen production yield of 33%. This has also been confirmed on the bio disk bio reactor by lowering the total pressure in the reactor of 0.11bar leading to a productivity and yield enhancement. The inter facial transfer surface play also a great role and was studied in 200ml batch fermentation. These experiences shows a 25 to 100% increase of hydrogen production yield by enhancing the mixing conditions of the media. Furthermore, these experiences shows influences of the culture conditions to the microorganisms metabolisms, observing the increasing activity of the formate hydrogen lyase enzyme, partially responsible of the hydrogen production.
