Africa-Press – Senegal. <\/strong><\/span>L\u2019extraordinaire odorat des chiens semble ne pas avoir de limites. Un million de fois plus ace\u0301re\u0301 que celui de l\u2019e\u0302tre humain, il est mis a\u0300 profit pour la chasse depuis des sie\u0300cles, ou pour d\u2019autres activite\u0301s comme la de\u0301tection d\u2019explosifs ou de stupe\u0301fiants. Plus re\u0301cemment, la recherche me\u0301dicale s\u2019en est e\u0301galement empare\u0301e. Ainsi, il a e\u0301te\u0301 de\u0301montre\u0301 que ces animaux e\u0301taient capables de de\u0301tecter des cancers, le diabe\u0300te ou le paludisme. Et qu\u2019il e\u0301tait par exemple possible de les entrai\u0302ner a\u0300 pre\u0301venir leurs mai\u0302tres lorsqu\u2019ils sentaient la survenue imminente d\u2019une crise d\u2019e\u0301pilepsie.<\/p>\n

Une e\u0301tude publie\u0301e dans The Journal of Parkinson Disease, re\u0301alise\u0301e par des chercheurs britanniques des universite\u0301s de Bristol et de Manchester en collaboration avec une organisation caritative, Medical Detection Dogs, de\u0301voile des aptitudes encore plus surprenantes. Deux chiens, un golden retriever de deux ans et un labrador de trois ans ont e\u0301te\u0301 entraine\u0301s durant une cinquantaine de jours a\u0300 distinguer des tampons imbibe\u0301s du se\u0301bum de malades de Parkinson et ceux de personnes non atteintes.<\/p>\n

Bumper et Peanut, as des as<\/b><\/p>\n

Dans les premiers temps de l\u2019expe\u0301rience, une dizaine d\u2019animaux avaient e\u0301te\u0301 se\u0301lectionne\u0301s. Mais plus l\u2019entrainement avanc\u0327ait et les difficulte\u0301s augmentaient, plus les candidats canins e\u0301taient e\u0301limine\u0301s. Au final, seuls deux d\u2019entre eux ont e\u0301te\u0301 capables d\u2019aller au bout de la se\u0301lection. Bumper, le golden retriever et Peanut, le labrador.<\/p>\n

Une fois cette e\u0301tape d\u2019apprentissage effectue\u0301e, les chercheurs ont soumis les animaux a\u0300 un test en double aveugle au cours duquel aucun expe\u0301rimentateur humain n\u2019e\u0301tait au courant des bons re\u0301sultats, ceci afin de ne pas influencer, me\u0302me inconsciemment, les toutous.<\/p>\n

Une centaine d\u2019e\u0301chantillons ont e\u0301te\u0301 soumis a\u0300 Peanut et Bumper. Ceux-ci ont correctement identifie\u0301 les tampons \u00ab Parkinson \u00bb dans 80% des cas et ont correctement ignore\u0301 95% des tampons \u00ab contro\u0302le \u00bb prouvant ainsi qu\u2019il est possible d\u2019entrainer les chiens a\u0300 de\u0301tecter les compose\u0301s volatiles odorants produits par la maladie de Parkinson.<\/p>\n

Vers des marqueurs pre\u0301coces de la maladie<\/b><\/p>\n

Au-dela\u0300 de cette confirmation que les chiens peuvent e\u0302tre des auxiliaires me\u0301dicaux d\u2019un genre nouveau, ce re\u0301sultat s\u2019inscrit dans la recherche de marqueurs fiables et pre\u0301coces de l\u2019affection. En effet, actuellement, la maladie de Parkinson est dans une impasse the\u0301rapeutique.<\/p>\n

Nul traitement ou me\u0301dicament n\u2019est ve\u0301ritablement efficace parce qu\u2019il peut s\u2019e\u0301couler une vingtaine d\u2019anne\u0301es entre le de\u0301but de la maladie et son identification formelle. Les premiers sympto\u0302mes passent souvent inaperc\u0327us et lorsque le diagnostic me\u0301dical est enfin pose\u0301, la maladie est trop avance\u0301e pour parvenir a\u0300 l\u2019enrayer.<\/p>\n

Pouvoir la repe\u0301rer plus to\u0302t permettrait ainsi de ralentir sa progression plus efficacement et de re\u0301duire l\u2019intensite\u0301 des sympto\u0302mes.<\/p>\n
