Abstract

De nombreux antigènes de protéines et de glycoprotéines sécrétés par Mycobacterium tuberculosis (Mt) ont étés identifiés comme étant des antigènes de Mt "précoces" du fait de la présence d'anticorps précoces chez des sujets infectés par Mt avant même que la maladie cliniquement décelable ne soit contractée. Ces antigène des Mt précoces, en particulier une protéine sécrétée de 88 kDa avec un pHi de 5,2 environ présente dans un filtrat de culture exempt de lipoarabinomannane Mt, une protéine caractérisée comme un antigène de Mt 85C, une protéine caractérisée comme un antigène de Mt MPT51, une glycoprotéine caractérisée comme un antigène de Mt MPT32, une protéine de 49 kDa avec un pHi de 5,1 environ, sont tous efficaces dans les techniques de dosages immunologiques pour le dépistage précoce et rapide de la tuberculose chez un sujet donné. L'invention décrit également des compositions antigéniques, des procédés et un nécessaire pour détecter efficacement un antigène de Mt précoce, un anticorps de Mt précoce ainsi que des complexes immunologiques de ceux-ci. Pour la première fois, il existe un marqueur de substitution permettant un dépistage peu onéreux des sujets qui présentent un haut risque d'infection par la tuberculose, en particulier les sujets infectés par le VIH-1 et d'autres sujets immunodéficients.
