Alternative strategies to combat antimicrobial resistance and their direct and indirect mechanisms of action. (A) Vaccination helps in preventing the course of infections by evolving immune cells (i.e. B cells Inline graphic, T cells Inline graphic) to develop an adaptive immunity by producing specific antibodies (Inline graphic) against important pathogens. (B) Chicken egg yolk antibodies provide effective treatment approach against several viral and bacterial diseases. (C) Probiotics (Inline graphic), prebiotics (Inline graphic), and synbiotics improve general health by selectively stimulating innate immune cells (Inline graphic). (D) Lytic bacteriophage or their purified gene products could be used to treat sepsis and few bacterial infections. (E) Quorum sensing quenchers (Inline graphic) could control virulence of pathogens by inhibiting the binding of auto-inducers (Inline graphic) to respective receptors. (F) Antimicrobial peptides (Inline graphic), bacteriocins (Inline graphic), and phytocompounds (Inline graphic) directly inhibit the bacterial growth by acting on bacterial cell membrane. (G) Modified CRISPR-Cas approach targets resistance genes in pathogens and reverse the selective pressure of resistance. (H) Metal-based nanoparticles (Inline graphic) help in blockage of enzyme pathways, alteration of cell wall, and nucleic material pathways.
