| Περίληψη: | Antimicrobial-resistant bacteria in agricultural waste represent a critical One Health concern. Anaerobic digestion of livestock waste is widely promoted; however, the fate of antimicrobial resistance and biocide tolerance in full-scale systems remains unclear, constraining safe digestate reuse. This study assessed phenotypic and genotypic resistance in Escherichia coli-like enterobacteria isolated from effluent and biofertilizer in a full-scale dairy anaerobic digestion system. A total of 173 isolates were screened for antimicrobial resistance genes (ARGs), antimicrobial susceptibility, multidrug resistance (MDR), and biocide inhibition-zone responses. No diarrheagenic virulence genes were detected. At least one screened ARG was detected in 91.0% of effluent and 83.3% of biofertilizer isolates. qacE∆1 was the most frequent marker and occurred significantly more often in effluent (70.8%) than biofertilizer isolates (44.0%; q = 0.00291). Phenotypic resistance to at least one antimicrobial was observed in 27.0% and 34.5% of effluent and biofertilizer isolates, respectively, while MDR occurred in 2.2% and 9.5% (p = 0.0521). tet(a) carriage was strongly associated with tetracycline resistance (OR = 20.9; q < 0.001).
