Hello,

you need to check on available research papers in the feild of DNA ,Becteria etc for example Multiple Antibiotic Resistance Gene Transfer from Animal to Human Enterococci in the Digestive Tract of Gnotobiotic Mice by Moubareck,1 N. Bourgeois,1 P. Courvalin,2 and F. Doucet-Populaire1 etc however metanlysis shows that animal does not show such human characteristics 

hope this helps you !
