Comparative Human-Poultry Fecal Resistome Profiling from Broiler Farms Reveals Diverse Antimicrobial Resistance Genes

Indiscriminate use of over-the-counter antibiotics has led to the rapid emergence of resistant genes in bacteria, with the ultimate crisis to global health. One of the prominent sectors with the antimicrobial resistance (AMR) concern is the farm animals that exist in close contact with humans where the environmental conditions are favorable for the rapid dissemination of pathogenic organisms and resistance genes. Hence, to understand the threat with environmental AMR, a detailed molecular insight is very important. In this study, fecal samples from both poultry and associated humans were studied by metagenomics analysis. From the results, a primary understanding on the microbial diversity difference could be generated from the selected samples. Here, the poultry samples were identified to have more microbial diversity. At the same time, several pathogens were found to be shared commonly between the hosts. Upon detailed examination, several AMR genes were also observed to be common between the poultry and human samples. The results of the study are highly relevant in light of the "One Health" concept where an integrated approach is targeted.
