Abstract

Extensive antimicrobial usage in animal farming plays a prominent role in the antimicrobial resistance (AMR) crisis and is repeatedly highlighted as an area needing development under the ‘One Health’ approach. Alternative therapies such as microbiome products can be used as prophylaxis to help avoid infectious disease. However, a limited number of studies have focused on AMR-targeted microbiome products. We conducted this systematic review by using PRISMA guidelines to screen for literature that have evaluated food animals’ health when administrated with microbiome products targeting antimicrobial resistance (AMR) or antibiotic-resistant genes (ARGs). We searched and examined studies from SCOPUS, Web of Science, Embase, and Science direct databases for studies published up to November 2021, restricted to the English language. The findings of this review showed that microbiome products have a promising capability to tackle specific AMR/ARGs coupled with animal’s health and productivity improvement. Furthermore, our study showed that probiotics were the most favourable tested microbiome products, with the most targeted resistance being to tetracycline, macrolides, and beta-lactams. While microbiome products are promising alternatives to antibiotic prophylactics, there is a dearth of studies investigating their efficacy in targeting AMR. Thus, it is highly recommended to further investigate, develop, and improve the microbiome, to better understand their utility and circumvent their limitations.

Keywords: AMR, antimicrobials, ARG, bacteria, food animals, microbiome, microbiome products, probiotics.
