PCR was used to identify the pathogen and we tested for eight viruses (HEV, Porcine reproductive and respiratory syndrome virus, PCV2, Classical swine fever virus, Porcine epidemic diarrhea virus, Transmissible gastroenteritis coronavirus, Porcine parvovirus and Pseudorabies virus) that are prevalent in Chinese pig farms. CONCLUSION: HEV and PCV2 co-infection in piglets was detected in four out of seven dead pigs from two pig farms in Hebei, China, producing severe pathological changes. In the present study, pathogen identification and the observation of pathological changes demonstrated a natural co-infection with HEV and PCV2 in the swine on two pig farms in Hebei Province, China. The lesions observed in the lung, liver, heart, kidney, lymph node, spleen and intestinal tract tissues were similar in all the pigs necropsied.	./cache/cord-261446-ro1wm0kf.txt	./txt/cord-261446-ro1wm0kf.txt
