The Woman’s loyalty to her Horse

She spent three hours holding its head above the tide after it got stuck in the mud on a beach in Australia.A horse gets stuck up to his neck in mud on a beach as the tide rises. His owner, Nicole Graham, who was enjoying an afternoon ride, stayed with him as rescuers struggled for three hours to pull him out. With moments to spare, the 500kg horse, named Astro, was freed with the help of a tractor and harness at Avalon Beach in Geelong, Victoria, Australia.Pics by Peter Ristevsk

Quelle sera la prochaine grande épidémie ?

AVIS D'EXPERT - L'analyse du Dr Jean-Claude Manuguerra, responsable de la cellule d'intervention biologique d'urgence à l'Institut Pasteur et président du comité de pilotage du réseau mondial d'alerte et d'action en cas d'épidémie. Les maladies infectieuses ont continuellement accompagné notre espèce. En particulier, de nombreuses épidémies ont influencé, et parfois même modelé de façon très importante, la dynamique évolutive des populations humaines au cours des millénaires. On peut citer ici les cinquante millions de morts liés à la pandémie de grippe espagnole de 1918-1919 et les épouvantables épidémies de peste noire, qui détruisirent environ 25 % de la population française au XIVe siècle. La rougeole et le paludisme tuent encore plusieurs millions d'enfants chaque année. Depuis la fin du XIXe siècle, d'extraordinaires efforts ont été accomplis pour lutter contre les agents infectieux, avec un succès spectaculaire dans les pays occidentaux. Le développement des conditions d'hygiène, les vaccinations, la large utilisation des insecticides, puis des antibiotiques conduisirent à une diminution phénoménale de la part des maladies infectieuses dans la morbidité et la mortalité. Dans les années 1950-1960, l'opinion largement répandue dans les pays occidentaux était que les maladies infectieuses allaient être mieux maîtrisées et ne représentaient plus la première priorité. Le succès de l'éradication de la variole, en 1977, renforça cette idée. Résistance Depuis, la situation s'est retournée. De nombreuses nouvelles maladies infectieuses sont apparues (le sida dû aux virus de l'immunodéficience humaine, ou VIH, la fièvre d'Ebola…), d'autres ont ressurgi dans des régions d'où elles avaient été éradiquées ou maîtrisées (tuberculose, choléra…), enfin quelques-unes ont vu leur distribution géographique s'élargir de façon spectaculaire (West Nile…). Parallèlement à l'émergence réelle, on assiste à une aggravation de la résistance de nombreuses bactéries et parasites aux antimicrobiens. Afin d'appréhender ces tendances globales, Kate E. Jones et coll. (Nature, 2008) ont étudié 335 événements d'émergence de 1940 à 2004. De façon surprenante, les émergences virales ont été minoritaires puisqu'elles ne comptent que pour un quart d'entre elles. La prédominance des bactéries résulte de l'apparition de résistance aux antimicrobiens. C'est parmi les 84 événements d'émergence virale chez l'homme que l'on trouve les émergences vraies, c'est-à-dire l'apparition réellement nouvelle d'un pathogène dans notre espèce, dont la présence résulte en général d'une transmission interespèces. Sur ces 84 émergences, 11 correspondent à des virus à ADN (4 familles), 9 à des virus à intermédiaire ADN (familles des VIH et du virus de l'hépatite B) et 64 à des virus à ARN (13 familles). Le nombre d'événements d'émergence ne reflète pas nécessairement l'importance de celle-ci pour la santé publique. Ainsi, la famille des VIH se classe au cinquième rang avec 7 événements dont 2 majeurs correspondent à l'émergence des VIH-1 et -2. Quant aux familles des virus de la fièvre jaune et du chikungunya, qui regroupent essentiellement des virus transmis par des arthropodes, elles ont produit 38 événements viraux, soit une petite moitié. Déforestation L'analyse des facteurs non virologiques fait ressortir que 11 catégories de facteurs majeurs sont associées à 82 % des émergences virales chez l'homme. Au premier rang, on trouve les changements dans l'usage des terres (la déforestation, par exemple) avec près d'un quart des événements. Ensuite, ce sont les changements dans l'industrie agroalimentaire (13 %), puis les voyages, les échanges internationaux (11 %), les changements dans les industries de la santé (10 %) et le changement de sensibilité de l'homme à l'infection (10 %). La plasticité génétique virale est déterminante pour le passage d'une espèce animale à une autre et à l'homme en particulier. Par leur taux intrinsèque de mutation élevé, les virus à ARN sont prompts à générer une descendance hétérogène génétiquement. Leur existence permet au virus, soit avant le passage d'une espèce à l'autre, soit après ce passage, de disposer d'une diversité de possibilités de caractères qui peut être utile au cours d'un changement d'environnement. La sélection de mutants permet au virus de continuer son adaptation à son nouvel hôte et d'y accroître sa «vitalité». C'est ainsi que les virus deviennent plus «compétitifs», notamment dans leur transmission interhumaine. En dehors des mutations, les échanges de portion ou de gènes entiers sont aussi de puissants moteurs de variations génétiques. Les agents qui peuvent infecter plus d'une espèce sont omniprésents. Près de 61 % des pathogènes humains sont des agents de zoonoses, dont près de 72 % sont liées à la faune sauvage. Les émergences sont le résultat d'un ensemble complexe de facteurs mêlés et situés à de multiples échelons: du niveau moléculaire à celui des modifications écologiques et sociétales. Les émergences vraies sont les plus à craindre. Peut-on donc dresser un portrait-robot du prochain pathogène émergent capable de créer la prochaine grande épidémie au XXIe siècle? Partant des constats énoncés ci-avant, il pourrait s'agir d'un virus à ARN, doué d'une grande plasticité génétique et contagieux à transmission respiratoire, d'origine zoonotique et qui aurait accompli son passage vers l'homme plusieurs fois avec un seul succès dans une région où se sont produits de grands changements dans l'utilisation des terres, puis il aurait été initialement amplifié chez l'homme à l'insu des autorités sanitaires au sein d'une mégalopole. Qui vivra verra!
