Effects of slurry from sulfadiazine- (SDZ) and difloxacin- (DIF) medicated pigs on the structural diversity of microorganisms in bulk and rhizosphere soil

► Antibiotic-derived effects on soil microflora studied under ecological relevant conditions. ► Antibiotic medication changed the organic and microbial composition of the excreted pig slurry. ► Effects of slurry with antibiotics on microorganisms emerged in bulk and rhizosphere soil. ► Effect levels were attenuated in rhizosphere soil, indicating a less vulnerable microflora.
