Presence of toxin-producing bacterial pathogens and associated risk factors in neonatal diarrhea of piglets on commercial sow farms in Vietnam

This study presents the first national-scale assessment of bacterial pathogens in NPD across Vietnamese sow farms. The findings highlight the high burden of toxin-producing bacteria, frequent co-infections, and multiple farm-level risk factors. Interventions such as targeted vaccination, optimized antibiotic use, improved weaning practices, and enhanced regional surveillance are essential for mitigating NPD impacts and improving piglet health outcomes in Vietnam.
