Core-resistome overlap between environments. a Networks where nodes represent environments with their node size proportional to the size of the environment’s core-resistome. The width of the edge is proportional to the number of core-resistome ARGs shared between two environments. Only overlaps of at least five ARGs are shown. b The heatmaps show the number of core-resistome ARGs shared between two environments for each antibiotic type. The labels Birds, Bovines, Mice, Pigs, Humans, and Infants denote metagenomes from the corresponding digestive system. Respiratory system and skin only include human samples. Qnr is an abbreviation for quinolone resistance
