ABSTRACT The study aimed to evaluate the antimicrobial resistance (AMR) patterns among fecal indicator bacteria and analyze characteristics of wastewater from anaerobic digestion (AD) treatment systems in swine farms. Escherichia coli Enterococcus spp. were identified by conventional molecular methods. AMR profiles quality analyzed using standard results indicated that primary resistances observed E. against AM, TE, SXT, DO. Among spp., highest was noted for followed E, CIP, NX. faecium showed NX, TE. Multidrug-resistant-E. enterococci 64.2 32.6%, respectively. Furthermore, CL-resistant VA-resistant reported. Compared with influent, proportion effluent decreased. This decline suggested AD effectively removed antimicrobial-resistant (ARB). However, high influent biochemical oxygen demand, total suspended solids, chemical demand levels demonstrated significant pollution. Therefore, farms should prioritize waste management regular maintenance enhance removal ARB pollutants. data only three farms, highlighting need future research a larger sample.
