a 96 well microtiter plate-based method for monitoring formation and antifungal susceptibility testing of candida albicans biofilms

Candida albicans, şimdi ABD hastaneleri, üçüncü en sık görülen enfeksiyon bozukluğu olan hastalarda kandidiyazis ve genişleyen bir nüfus mantar enfeksiyonlarının en sık nedeni olmaya devam etmektedir . Kandidiyazis farklı tezahürleri biyofilm oluşumu, hem ev sahibi doku ve / veya tıbbi cihazlar (yani kateter) ile ilişkilidir. Biyofilm içinde hücrelerinin konağın immün yanıtları ve antifungallerin eylem korunur Biyofilm oluşumu, negatif klinik etkileri taşır. Biz C. oluşumu için, basit, hızlı ve güçlü bir in vitro model geliştirdik albicans biyofilm antifungal duyarlılık testi için de kullanılabilir 96 mikrotiter plakalar, biyofilm. Bu testte okuma, metabolik olarak aktif fungal biyofilm hücreleri tarafından XTT azaltılması (tetrazolium tuz) dayalı, kolorimetrik. Tipik bir deneyde, antifungal duyarlılık testi için ek bir 24 saat, biyofilm oluşumu için yaklaşık 24 saat sürer. Çünkü sadeliği ve yaygın olarak kullanılan laboratuar malzemeleri ve ekipman kullanımı, bu tekniğin, biyofilm araştırma democratizes ve antifungal duyarlılık testi mantar biyofilm standardizasyon doğru önemli bir adımı temsil etmektedir.
