Pathological Mechanism and Pr evention and Control Measures of Por cine Epidemic Diarrhea

Abstract

This article elaborateshow the porcine epidemic diarrhea virus pathogenic mechanism and harm in pigs. Porcine epidemic diarrhea is a contagious disease with different therapeutic effects on pigs of different ages. It shares common characteristics with coronaviruses, like suppressing the production and function of interferon, replicating extensively in infected pigs. In addition, there are similarities between the symptoms of porcine epidemic diarrhea virus and transmissible gastroenteritis virus, scientists devote to find the characteristics of PEDV to help farmers distinguish between the two diseases and treat the infected pigs in time to reduce loss. Porcine epidemic diarrhea is more common at the transition from winter to spring, when most piglets are born at this time. The infected pigs with various clinical symptoms including watery diarrhea, vomiting and dehydration. These symptoms lead to rapid and irreversible dehydration and death of piglets, and it has had a serious negative impact on the development of the pig farming industry. This means that the prevention and control of PEDV is necessary. Scientists collect data on the targeted structure of the spike protein in PEDV to facilitate the development of more broadly effective vaccines by focusing on studying the mechanisms of action, pathological features and prevention methods in multiple aspects. These prevention and control measures provide practical guidance for the scientific handling of the epidemic, and explore its research value in etiology and epidemiology, which is of great significance for ensuring the healthy development of the pig farming industry.
