The over-prescription and misuse of microbiostatic or microbicidal chemical compounds led to the emergence of antibiotic resistance
and multiresistance in bacterial strains. The genetic resistance of bacterial cells is amplified when they are growing in biofilms,
known for the high phenotypic resistance or tolerance to antimicrobial agents, explaining their high incidence in the etiology of infectious
diseases. Currently, there are many research groups in the entire world focusing their investigations on the elucidation of different aspects
of bacterial intra- and intercellular communication dependent on the cellular density and regulated by the quorum-sensing and response
system (QS), including the isolation of natural compounds, as well as the synthesis of biomimetic analogues or antagonists of QS molecules,
with potential prophylactic and therapeutic value for the management of animal and human infections, as well as for fighting the
negative consequences of biofouling phenomenon occurring in natural environments. Taking into account the vital importance of the
antifouling protection of the photosyntetic organisms in the natural marine environment, the screening of marine organisms for finding
new anti-pathogenic, non-lethal compounds represents a promising perspective for the development of efficient preventive and therapeutic
strategies of bacterial infections produced by resistant phenotypes, associated with biofilm development.
