Malgré de multiples études, les interrelations entre l’exercice, le stress et la réponse immune sont peu définies. Or, la compréhension de ces interrelations pourrait jouer un rôle très important dans l’amélioration de la santé et des résultats sportifs des athlètes. En effet, l’exercice peut être reconnu comme un stress. Il induit des modifications de l’équilibre homéostatique qui peuvent à leur tour altérer la réponse immunitaire de l’hôte et donc sa susceptibilité aux maladies. L’adrénaline est la molécule essentielle de tout processus de stress. La technologie des microdamiers, outil majeur d’investigation transcriptomique, permet l’étude de l’expression génique de l’ensemble du génome. Son utilisation devrait donc permettre de mieux caractériser et définir les interrelations entre l’exercice, le stress et la réponse immune. Cette revue recense les interrelations connues entre la réponse immune à un stress adrénergique d’une part et la réponse immune à l’exercice d’autre part. Elle considère en outre la contribution potentielle des microdamiers à une meilleure compréhension des effets d’un stress, et plus particulièrement celui lié à l’exercice, sur l’immunité. [less ▲]

Le cheval barbe occupe une place de choix dans l’histoire, la culture et les traditions algériennes ; il est à la base des principales races équines maghrébines. Dix-neuf mensurations ont été réalisées sur 151 chevaux barbes et arabe-barbes, purs et présumés (origines incertaines), tous âgés de trois ans et plus. À partir de celles-ci, six indices corporels ont été calculés et le poids vif estimé. Les relevés de la robe et du profil céphalique ont également été effectués. [less ▲]

Cottonseed by-products arevery high in nutrients and theirchemical composition varieshighly according to the varietiesof cotton and the various treatmentsaiming at extracting oil.Their use in animal nutrition, andparticularly in broilers, is especiallylimited by the free gossypolwhich can damage varioustissues and also decreases theperformances of growth and dietefficiency. The incorporation ofcottonseed meal in broilers dietmay be increased following chemicalbinding of free gossypol,but these methods have drawbacks.Ferrous sulfate denaturesfeed and the use of lysine to bindgossypol is limited by the expensivenessof this product while thebiological fermentation is verycomplex and inapplicable, as tonow, on a large way. Glandlessvarieties could be incorporatedat a very high level in diets andtherefore could contribute todecrease the protein feed requirements.Unfortunately, agronomicconstraints associated to thesecrops have limited the research inthis way. The production of varietiesin which gossypol secretionwould be inhibited before theseed germination should alleviatethe limitations associated to cottonby-products. [less ▲]

Staphylococcus (S.) aureus is a major pathogen for mastitis in dairy cattle. In most cases, S. aureus causes long-lasting subclinical and chronic bovine mastitis and leads to significant economic losses by reducing the quantity and the quality of the milk produced. The pathogenesis of S. aureus mastitis includes the ability to persist within host cells and involves multiple virulence factors including toxins, surface proteins and polysaccharides. The numerous vaccines that have been developed induce a specific immune response against these different factors. These different vaccine approaches are described and classified depending on the target antigen used. Moreover, some recent vaccine strategies against human S. aureus infections are also discussed and could eventually be used for the design of new bovine vaccines. Although most of bovine vaccines induce specific humoral response, to date, no vaccine has been described to protect efficiently against experimental and naturally occurred bovine S. aureus mastitis. In conclusion, this type of immune response and the broad antigenic variability of S. aureus strains can partially explain the lack of protection observed during most of vaccine trials. [less ▲]

In many songbirds species, wherein we can find the domestic canary (Serinus canaria), singing is generally produced either to defend a territory or to attract a mate. The Song Control System is a neural specialization, mostly located in telencephalic regions of the brain and associated to the control of song learning, perception and production. External factors such as testosterone (T), photoperiod and social cues have been described to modulate singing behaviour. Parallel to the song behaviour, some of the song control system nuclei (HVC, RA and Area X) demonstrate a puzzling amount of seasonal plasticity. Their volumes varies seasonally based on changes in cell spacing, neuropile size, dendritic arborisation and in the case on the nidopallial nucleus HVC on the incorporation of newborn neurons. We present here a review of this curious phenomenon of adult neuroplasticity associated to a complex behaviour, which doesn’t occur as far as we know in the mammalian adult brain [less ▲]

Lesions to the horse’s tendon are very frequent and are a non negligible reason for early retirement of sport and leisure horses. For decades man has been searching for “the” treatment but unfortunately most of the known treatments have empiric bases and very few have actually proven their real efficiency. Diagnostic techniques like ultrasound allows to better evaluate the improvements made in tendonitis therapies. Stem cells and gene therapy are probably the most innovating of them, but their long-term effectiveness still has to stand the test of times. This article gives an overview of the possible treatments of tendonitis today. [less ▲]

The synovial joint, by load bearing and by minimal wear and minimal friction conferring, is considered as a perfect tribological system. During these last years, researchs in articular biomechanics have been performed to study how the joint friction coefficient, a dimensionless measure which represents the ratio between the frictional force on the normal force, was close to zero. Today, there is still no consensual explanation and the articular prosthesis partially imitates the biological mechanics. This review describes the composition and the general properties of the synovial joint components. Additionally, different theorical models, on the tribology of the articular triplex cartilage-synovial fluid-cartilage, are explained. [less ▲]

Lesions to the horse’s tendon are very frequent and are a non negligible reason for early retirement of sport and leisure horses. For decades man has been searching for “the” treatment but unfortunately most of the known treatments have empiric bases and very few have actually proven their real efficiency. Better knowledge of tendon anatomy and pathophysiology of tendonitis together with evolutions in diagnostic techniques like ultrasonography allows us to better evaluate the improvements made in tendonitis therapies today. The first part of this article gives a review on tendon structure, tendon healing and ultrasonographic evaluation of the tendon. In the second part an overview of therapeutic options for tendonitis will be discussed. [less ▲]

The purpose of this work was to establish one or several short protocols for magnetic resonance imaging of the equine cadaver foot, using the most appropriated sequences in a limited number of planes, allowing the assessment of the anatomical structures. Three feet were scanned with most of the sequences used for evaluation of the osteo-articular system in seven different ection planes (1 sagittal, 3 dorsal and 3 transverse planes). The sequences and the planes in which the anatomical structures were best assessed were selected by scoring the visualization of the anatomical structures. Three short protocols are proposed. The first protocol uses spin echo sequences, one fat suppressed sequence and one sequence to evaluate the cartilage. The second adds gradient echo sequences to show the sites of haemorrhage and the articular cartilage. The third protocol adds special section planes, the first perpendicular to the distal insertion of the deep digital flexor tendon and the second perpendicular to the collateral ligaments of the distal interphalangeal joint and adds another sequence combining cartilage visualization and fat suppression.

The effect of feed containing cassava leafs and peels was assessed on 126 local guinea fowls animal performance, production costs and meat quality over a period of 28 weeks in humid tropical climate of the South Benin. After 12 weeks of classical feeding, animals were randomly allotted in three groups of 42 for the finishing period: the group 1 received a control diet while, in group 2, 8% and 35 % of cassava leafs and cossets were respectively incorporated, vs. 6 % and 25 % in group 3. At the end of the trial, eighteen guinea fowls per group were slaughtered in order to determine characteristics of the carcass and meat quality. Individual daily feed intake was higher in the control group than in the groups 2 and 3. Animals from control group shown higher growth rate (5.0 g/d) (P<0.05) than in groups 2 and 3. Consequently, feed conversion ratios were similar in the three groups with values of 7.5, 6.7 and 6.9, in groups 1, 2 and 3, respectively. At the end of the trial, animals in control group were heavier than those in groups 2 and 3 (P<0.05). No negative influence of cassava cossets and leaf meals was observed on carcass quality in the experimental diets. Feed costs per kg live weight were reduced by 24.6 and 21.0% in groups 2 and 3, respectively, when compared to control group. Guinea fowl production appears thus more profitable with feed containing cassava leaves and cossets. Consequently, these ingredients could be alternative sources of energy and protein, with emphasis during the finishing period. [less ▲]

Les pneumonies bactériennes constituent un problème majeur dans l'élevage et l'engraissement des bovins, avec des répercussions très élevées en termes de morbidité et de mortalité. Parmi les différentes causes biologiques recensées, Mannheimia haemolytica tient le haut de l’affiche puisqu’elle est connue comme agent pathogène compliquant principal, voire systématique. Une de ses particularités est qu’elle ne déclenche de pneumonie broncho-alvéolaire fibrino-hémorragique que chez les ruminants. Les lésions observées résultent d’une nécrose en masse des neutrophiles et macrophages et du relarguage de leurs différents constituants. Au niveau moléculaire, cette spécificité trouve son origine dans l’intimité de la liaison entre la leucotoxine, le facteur de virulence majeur de la bactérie, et la sous-unité CD18 des récepteurs de surface leucocytaires bêta2-intégrines. La revue décrit cette liaison et ses conséquences aux niveaux macroscopique et microscopique, avant de faire le point sur les dernières avancées de la recherche et d’ébaucher quelques perspectives thérapeutiques.
