Comparison on the diversity of antibiotic resistance genes of three rodent species
Antibiotic resistance genes(ARGs)have attracted widespread attention as a new global pollutant,mainly due to the abuse of antibiotics.To investigate the diversity of ARGs in three rodent species,we used metagenomic sequencing analysis to analyze the diversity of antibiotic resistance genes of 17 individuals of Apodemus peninsulae and 17 individuals of Myodes rufocanus collected from Mudanfeng,and nine individuals of Apodemus agrarius collected from Sandaoguan.A total of 19 types and 248 subclasses of ARGs were detected in the three rodent species.Seven ARGs showed significant difference and five ARGs showed extremely significant difference be-tween M.rufocanus and A.agrarius.Seven ARGs showed significant difference and four ARGs showed extremely significant difference between A.peninsulae and A.agrarius.Four ARGs showed significant difference and five ARGs showed extremely significant difference between M.rufocanus and A.peninsulae.ARGs showing high abun-dance in three rodents were macrolides,lincoamides,tetracyclines,and β-lactams.ARGs were widely distributed in the three rodent species.The significant differences in ARGs among different species might be due to the different distribution areas and their diet differentiation.The study could provide a basis for further studies of ARGs in mice and improve the understanding of the harm of ARGs transmission.
