the mods method for diagnosis of tuberculosis and multidrug resistant tuberculosis

活動性肺結核の患者（TB）は、患者を硬化し、新たな感染症の予防の両方に不可欠な活動性結核を診断すること、毎年10月15日他の人に感染する。さらに、耐性結核（MDRTBを）多剤の出現は、その薬剤耐性の検出は、薬剤耐性菌の拡散を阻止するために必要であることを意味する。顕微鏡観測薬剤感受性（MODS）アッセイは、TBとMDRTBの高性能の検出のための低コスト、ローテクのツールです。結核菌（MTB）は、微細なMTBの成長は、固形培地上のコロニーの肉眼的外観を待っているよりも早期に液体培地で検出し、可能な）固形培地2に比べて液体培地でより速く成長する1）：MODSのアッセイは、3つの原則に基づいていますその成長は、サブカルチャーは、実行をする必要がない、それは薬イソニアジドとリファンピシンがMDRTBの同時直接検出を可能にするためにMODSのアッセイに組み込むことができる非定型抗酸菌や真菌や細菌汚染3）と区別できるように、MTBの特徴です。間接的な薬剤感受性試験。競合する現在の診断は、喀痰塗抹標本と低感度、固体培地の文化、既存の液体培地培養法と法外に高いコスト、およびMDRTBを検出する間接的な薬剤感受性試験のためにサブカルチャーを行うために必要と診断されるまでに長い遅延によって妨げています。対照的に、非独占的なMODSの方法は、結核とMDRTBための高感度を有し、比較的迅速な培養法であり、MDRTBの同時薬剤感受性試験を提供し、リソースが限られた結核のためのテストのためのすぐ下に$ 3の設定にアクセス可能であり、 MDRTB。
