Abstract

MÉTODOS DE DIAGNÓSTICO DE TUBERCULOSE E DE DIFERENCIAÇÃO ENTRE TUBERCULOSE ATIVA E LATENTE. São fornecidos composições e métodos para detectar infecção por Mycobacterium tuberculosis (MTB) em um paciente suspeito de estar infectado com Mycobacterium tuberculosis e para distinguir entre infecção por tuberculose ativa e latente. Os métodos também podem ser usados para monitorar a progressão da infecção por MTB ou para monitorar o tratamento de pacientes infectados por MTB. São utilizadas alterações no nível de expressão de genes para auxiliar no diagnóstico, prognóstico e tratamento da tuberculose.
