Le test MODS est destiné aux ressources limitées. Pour la première fois, MODS apporte la capacité de détection rapide de la culture liquide de la tuberculose et la tuberculose multirésistante aux ressources limitées à un peu moins de 3 $ par test. MODS est un non-propriétaires, méthodologie itérative, et la communauté MODS est toujours intéressé à l&#39;amélioration d&#39;autres laboratoires ont réussi à faire. Une préoccupation récurrente est la biosécurité de la culture des milieux liquides de la tuberculose,...

the mods method for diagnosis of tuberculosis and multidrug resistant tuberculosis

Les patients atteints de tuberculose pulmonaire (TB) active infecter d&#39;autres personnes de 10 à 15 par an, ce qui rend le diagnostic de tuberculose active essentielle à la fois à guérir le patient et la prévention des nouvelles infections. Par ailleurs, l&#39;émergence de la tuberculose multirésistante (tuberculose à bacilles multirésistants) signifie que la détection de la résistance aux médicaments est nécessaire pour arrêter la propagation de souches résistantes aux médicaments. L&#39;observation microscopique-sensibilité aux médicaments (MODS) de dosage est un faible coût, faible technicité outil de haute performance de détection de la tuberculose et TB-MR. Le test MODS est basé sur trois principes: 1) de Mycobacterium tuberculosis (MTB) croît plus vite dans les milieux liquides que sur milieu solide 2) la croissance VTT microscopiques peuvent être détectés plus tôt dans les milieux liquides que d&#39;attendre que l&#39;aspect macroscopique des colonies sur milieu solide, et que la croissance est caractéristique de VTT, qui lui permet d&#39;être distinguée de la contamination mycobactéries ou fongiques ou bactériennes atypiques 3) les médicaments isoniazide et la rifampicine peuvent être incorporés dans le test MODS pour permettre une détection directe simultanée de tuberculose à bacilles multirésistants, éliminant la nécessité d&#39;une sous-culture à effectuer un test de drogue indirects susceptibilité. La concurrence des diagnostics actuels sont entravés par une faible sensibilité aux frottis de crachats, de longs délais jusqu&#39;à ce diagnostic avec la culture médiatique solide, avec des coûts prohibitifs des méthodes existantes de liquide milieux de culture, et la nécessité de ne sous-culture pour les tests de sensibilité aux médicaments indirectes pour détecter la tuberculose multirésistante. En revanche, la méthode non-propriétaires MODS a une sensibilité élevée pour la tuberculose et tuberculose à bacilles multirésistants, est une méthode de culture relativement rapide, offre simultanée des tests de sensibilité aux médicaments pour la tuberculose multirésistante, et est accessible aux ressources limitées à un peu moins 3 $ pour les tests pour la tuberculose et TB-MR.
