ln 1996, the cotton subsector in Burkina Faso experienced a great crisis which was drama-like here and there. An exceptionally high infestation of cotton plants by the main pest, Helicoverpa armigera (a density of 167n500 worms par hectare) on treated plots whereas the theoretical intervention threshold is ranging from 5,000 to 12,500 Army-worms per hectare could not be controlled by the released insecticides. This year, the infestation intensity was at least sirnilar with the one of the year 1991 in which harvest losses had been estimated at 50,000 tons of seed cotton (NIBOUCHE 1994), i.e. a loss of about 20 billion francs CFA. The aftermath was really heavy for the productucers, SOFITEX and the Burkina state. Four years later, well informed and well-advised experts take into consideration the natural factors and hurnan opcrational factors that are the source of this economie drarna : findings from two independent expert reports produced according to Laboratory Good Pratices (GLP) at the request of civil society on sorne pesticides, highlited concordantly their poor quality (low active ingredient. content, poor quality of formulations). This work, whilst restoring truth in a fair and unbiased way, states the reasons for our past and current failures as weil as the reasons for our future successes. By proposing a new approach to studies on the efficacy of cotton insecticides, tbis work contributes to the seeking of a better phytosanitary protection for cotton in the countries of the sub-region.

M. haemolytica serotype A1 (formerly known as Pasteurella) is the most important and commonly isolated bacterial pathogen from fatal cases of bovine fibrinous pleuroneumonia. M. haemolytica and its two principal toxins, the lipopolysaccharides (LPS) and the leukotoxin (LktA) induce the recruitment, the activation and the necrosis of neutrophils involved in the pathogenicity of bovine pneumonic mannheimiosis (BPM). The objective of this study was to determine whether systemic therapy with carprofène (Rimadyl®*), a non-steroidal anti-inflammatory drug, improves the disease development in an acute experimental model of BPM. The experimental pathology was induced by trans-tracheal inoculation of M. haemolytica and toxins at T0. One hour post-inoculation, six calves were treated intravenously with carprofen (1,4 mg/kg) while six placebo-treated calves received dose-matched volumes of sterile saline. The clinical and biochemical parameters were measured at one (T+1), three (T+3) and seven (T+7) hours after inoculation. Disease scores for carprofen treated calves were significantly lower than those for placebo-treated controls six hours (T+7) after treatment. These results were associated to a significantly oxygen saturation decrease at T+3 and a significantly blood lactate increase at T+7 in the control calves. Moreover, pulmonary lesions were significantly less extensive than those in the control group. Taken together, this finding suggest that pharmacological modulation by carprofen of pulmonary inflammation after appearance of acute BPM clinical signs leads to calves’ health enhancement and reduces the extent of gross pneumonic lesion.

Cette communication présente une réflexion sur le type de tâches à proposer lors de l évaluation certificative, ensuite sur les critères à prendre en compte et enfin sur les indicateurs de réussite. Cette réflexion repose d'une part sur un programme de recherche-action portant sur l optimisation de l expression orale en anglais/langue étrangère [2000-2002], et sur un autre programme de recherche-action portant sur l identification et la déconstruction de stéréotypes liés à la langue et à la culture étrangères (néerlandais et français) [2002-2004], et d'autre part sur les travaux réalisés au sein de la Commission de Pilotage du Système éducatif.
