Promising Approaches Based on Bioimaging Reporters for Direct Rapid Detection of Mycobacterium tuberculosis

Tuberculosis remains a serious global public health challenge and requires the development of rapid, sensitive, and specific diagnostic tools for effective treatment and disease control. Bioimaging reporters are promising diagnostic tools that exploit the unique biochemical properties of <i>Mycobacterium tuberculosis</i> for real-time detection of viable cells from clinical samples. Moreover, these methods offer significant advantages over the conventional methods currently used in practice, including reduced assay time, increased specificity, and the ability to discriminate viable cells from dead cells. In this review, we highlight reporters of a different nature that the enable direct detection of <i>Mycobacterium tuberculosis</i>, eliminating complex sample preparation. Such reporters could serve as powerful tools in fluorescence microscopy, provide alternative strategies for automated culture-based diagnostic systems, and offer new approaches for developing point-of-care methods and diagnostic devices suitable for clinical practice.
