Social Networks and Age Shape the Antibiotic Resistance Landscape in Primate Guts
A new metagenomic study on wild Tibetan macaques reveals a complex gut resistome dominated by multidrug resistance genes. While overall antibiotic resistance gene (ARG) diversity was not affected by host age, sex, or social connections, these factors significantly influenced the abundance of specific, high-prevalence ARGs. Notably, age emerged as a key driver structuring the co-variation network between core gut bacteria and ARGs, offering fresh ecological insights into the dynamics of antimicrobial resistance in social animals.
Study Significance: This research provides critical data on the natural reservoirs of antimicrobial resistance in wildlife, a key factor in understanding the global spread of resistance. For microbiologists and public health professionals, it underscores that host demographics and social behavior are important variables in predicting the abundance of specific resistance genes within a microbiome. This ecological perspective is vital for modeling the transmission of resistance from wildlife populations and for developing more nuanced surveillance strategies for emerging pathogens.
