Testing of experimental compounds in a relapse model of tuberculosis using granulocyte-macrophage colony-stimulating factor gene-disrupted mice.
This study describes an in vivo model for evaluating the sterilizing activity of compounds against persisting Mycobacterium tuberculosis. The initial treatment with isoniazid and rifampin in granulocyte-macrophage colony-stimulating factor gene-disrupted mice reduced the number of bacteria more than 99% within 3 weeks. A subsequent treatment with individual drugs was performed to assess their activity on the 1% of remaining bacilli and disease relapse.
