Comprehensive profiling of antibiotic resistance, virulence genes, and mobile genetic elements in the gut microbiome of Tibetan antelopes.

ABSTRACT: Tibetan antelopes, native to high-altitude plateau regions, play an important role in the local ecosystem. Their gut harbors antimicrobial-resistant microbes, including potential pathogens. To explore this, we analyzed 33,925 metagenome-assembled genomes (MAGs), including 7,318 from 68 Tibetan antelopes sequenced in our laboratory. We first profiled the composition of antibiotic resistance genes (ARGs) and then examined their associations with virulence factor genes (VFGs). In total, 2,968 ARGs were identified, conferring resistance to 23 antibiotic classes, with elfamycin resistance being most prevalent. Two ARGs were located on phage-derived sequences, though their phage taxonomy could not be resolved. ARGs were significantly correlated with VFGs, particularly genes linked to adherence a
