Fig. 3: Occurrence of selected ARGs in livestock waste in different countries.
From: Antibiotic resistance genes from livestock waste: occurrence, dissemination, and treatment
ARGs have been detected in livestock farms in 95 countries/regions (coral-colored; data presented in Table S6). China, the United States, and the European Union are three most frequently studied countries/regions. The size (diameter) of filled pies represent the total ARGs absolute abundance (with different solid colors representing different ARGs classes) while hollow pies represent the ARGs relative abundance. China, which has a relatively high use of antibiotics for animal farming, exhibits a relatively high abundance of ARGs in livestock waste.
