Popis: The emergence of multi-drug resistant bacteria has limited therapeutic options for the treatment of bacterial diseases in both human and veterinary medicine. This has resulted in an urgent need for novel agents to treat infectious diseases. Veterinary medicine is further constrained by the need to ensure that our emerging therapeutics have minimal or no impact on resistance in human pathogens. Thus, there has recently been increased attention given to the development of alternative treatments for infectious disease in animals. The domain of alternative therapies, which includes antimicrobial peptides, bacteriophages, probiotics, and immunomodulators, provides a means to directly inhibit the ability of a pathogen to damage the host while optimally, not imposing a selective pressure favouring antibiotic resistance. However, it is recognized that bacterial pathogens have the capability of expressing a variety of virulence factors, necessitating a clear understanding of the specific target for that therapeutic intervention. This manuscript explores the various virulence mechanisms, the potential utility of developing novel anti-virulence agents for counteracting the expression of diseases associated with veterinary species, and some of the unique regulatory hurdles to be addressed within the framework of a new animal drug application. We conclude with the public health concerns to be considered as these agents are integrated into the veterinary therapeutic arsenal. Our hope is that this manuscript will provide a platform to stimulate discussions on the critical questions that need to be addressed.
