This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/policies/article-withdrawal). This article has been retracted at the request of the Authors and the Editor-in-Chief. After acceptance of the manuscript, the Authors discovered that the animal experimental control group was infected, which makes the findings presented in the paper invalid. Specifically, they noted that the intestinal villus in pathological tissue sections of the negative group exhibited slight shedding, resembling PEDV infection. Further investigation revealed that the pig farms supplying the experimental animals experienced occasional outbreaks of PEDV infections. The Editor-in-Chief agreed that this article must be retracted and no longer has any confidence in the validity of the data presented in the manuscript.
