TL;DR: This Personal View raises awareness of the novel photoantimicrobial technologies that offer a viable alternative to conventional drugs in many relevant application fields, and could thus slow the pace of resistance development.

TL;DR: The results suggest that aPDT using Tri-Py+-Me-PF represents a promising approach to efficiently destroy bacteria since after a single treatment these microorganisms do not recover their viability and after ten generations of partially photosensitized cells neither of the bacteria develop resistance to the photodynamic process.

TL;DR: Bacteria isolated from females were less resistant than those isolated from males and this difference increased with the patient age, but the fluoroquinolones should not be suitable to treat male infections and the trimethoprim-sulfamethoxazole shall not be used in the treatment of UTI at this level.

TL;DR: This review addresses the interactions between photosensitizers and bacterial cells, the ultrastructural, morphological and functional changes observed at initial stages and during the course of photodynamic inactivation, the oxidative alterations in specific molecular targets, and a possible development of resistance.

TL;DR: The complete inactivation of both bacterial strains with low light fluence means that the photodynamic approach can be applied to wastewater treatment under natural light conditions which makes this technology cheap and feasible in terms of the light source.
