Severe Diarrhea Outbreaks in Newborn Piglets in China Associated With Porcine Rotavirus B.

ABSTRACT: Rotavirus B (RVB) is among the enteric pathogens that can cause gastroenteritis in humans and various animals. However, severe diarrhea in newborn piglets has rarely been reported to be linked to porcine RVB (PoRVB). From 2023 to 2024, outbreaks of newborn piglet diarrhea with 20%-50% morbidity and 4%-10% mortality occurred in three herds situated in Anhui, Liaoning, and Jilin provinces of China. Notably, all samples from these herds tested negative for porcine epidemic diarrhea virus (PEDV), porcine deltacoronavirus (PDCoV), PoRVA and transmissible gastroenteritis virus (TGEV). To identify the causative pathogens of the severe diarrhea in newborn piglets, high-throughput sequencing (HTS) was performed on pooled and individual samples collected from each farm. The results revealed that the
