Multidrug-resistant tuberculosis (MDRTB) infections that continue to increase in frequency globally have progressed to become extremely drug-resistant tuberculosis (XDRTB). The therapeutic problems associated with MDRTB pale in comparison to those for XDRTB where mortality is high.

Over a period of 14 years, the authors have studied thioridazine, an old neuroleptic, that has been shown to have in vitro activity against intracellular Mycobacterium tuberculosis, regardless of its antibiotic resistance status, thioridazine cures infected mice of antibiotic-susceptible and multidrug-resistant tuberculosis (TB) infections and, when used in combination with antibiotics used for therapy of TB, renders the organism significantly more susceptible.

Previously, the antipsychotic, non-antibiotic compound flupenthixol dihydrochloride (Fp) was shown to exhibit distinct in vitro antibacterial activity against Gram-positive and Gram-negative bacteria and to significantly protect Swiss albino mice challenged with a known mouse virulent salmonella.

Chlorpromazine (CPZ) was exposed to a 266 nm laser beam for different periods of time ranging from minutes to 24 h. At intervals, the products from irradiation were evaluated by thin-layer chromatography (TLC) and evaluated for their activity against mycobacteria of human interest (Mycobacterium tuberculosis, M. avium, M. intracellulare and their corresponding reference strains or clinical isolates).

A quorum is the smallest number of people able to organize the decisions concerning functional activity. Similarly microbes use chemical signal molecules to make population size-dependent “decisions” by changing their gene regulations.
