The composting process has been shown to effectively reduce antimicrobial resistance (AMR) in animal manure, but its influence on surrounding airborne AMR remains unknown, particularly with regard human-pathogenic antibiotic-resistant bacteria (HPARB). In this study, air and paired compost samples were collected from a full-scale facility, the antibiotic resistome, microbiome, HPARB systematically analyzed both two habitats using metagenomic analysis. Current result uncovered profiles of air, showing that significantly more assembled than samples. Airborne pathogens harboredan increased abundance diversity genes (ARGs) virulence factor (VFGs) comparison compost-borne HPARB. core resistome represents 18.58% overall ARG subtypes, contributing 86.31% abundance. A higher number enriched ARGs (2.16- 13.36-times higher), including mexF, tetW, vanS, observed compared As an important human pathogen, Mycobacterium tuberculosis was prevalent carried (6) VFG (130) subtypes those compost. risk score detected for facility hospital urban environments. This study revealed enhanced through comparative experiments between habitats. It highlighted unrecognized risks associated site provided scientific basis accurately assessing health outcomes caused by occupational exposure.
