摘要
Abstract
In January 2026,an acute diarrhea outbreak occurred among newborn piglets from 14 litters in the farrowing house of a large-scale pig farm in Guangxi,involving 180 diseased piglets with 30 deaths.The farm administered conventional antibiotics and antidiarrheal drugs to affected piglets yet achieved unsatisfactory therapeutic effects,posing a severe threat to piglet survival rate and production efficiency.To contain the epidemic,identify the causative pathogens,develop targeted prevention and control protocols and mitigate economic losses,fecal samples and fecal swabs collected from diarrheic piglets were subjected to pathogen detection and genotyping.The results showed that all samples tested negative for porcine epidemic diarrhea virus(PEDV),while some samples were positive for group A rotavirus(RVA)and group C rotavirus(RVC).Homology analysis revealed that the prevailing RVA strains responsible for the outbreak belonged to two genotypes,G5P6 and G5P13.Based on the diagnostic findings,the farm adopted integrated prevention and control measures including enhanced environmental disinfection and thermal insulation,targeted vaccination and drug intervention for sick piglets,which rapidly and effectively curbed the epidemic.This study confirmed that the acute diarrhea outbreak of piglets on this farm was mainly caused by co-infection with RVA genotypes G5P6 and G5P13.关键词
