Possibilities of Using Trehalose Probes for Detection of Mycobacterium tuberculosis

Trehalose probes seem to be a promising area of tuberculosis diagnosis, these probes are capable of selectively penetrating Mycobacterium tuberculosis. These probes generate a fluorescent signal, enabling detection of mycobacteria. To analyze the current state of knowledge and prospects of trehalose probes as a new approach for rapid detection of Mycobacterium tuberculosis, a systematic review of scientific literature was conducted. The main types of probes include fluorogenic probes, "fluorophore-quencher" based probes, and photoactivatable probes. Trehalose probes enable selective detection of mycobacteria due to specific trehalose uptake and incorporation into the cell wall, followed by fluorescence activation. These probes allow for the detection of mycobacteria in sputum samples without complex sample preparation or washing. The method allows differentiation of viable and non-viable cells and can also be applied for drug susceptibility testing.
