Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces SN/T 1699.1-2006 "Microseline Neutralization Test Procedures for Porcine Epidemic Diarrhea", SN/T 1699.2-2006
"Directive immunofluorescence test protocol for swine epidemic diarrhea virus", SN/T 1699.3-2006 "Indirect spot enzyme coupling for pig epidemic diarrhea"

Main technical changes compared with SN/T 1699.1-2006, SN/T 1699.2-2006, SN/T 1699.3-2006
as follows.
--- Increased the method for isolation and identification of porcine epidemic diarrhea virus;
--- Added reverse transcription-polymerase chain reaction method;
--- Added real-time fluorescence reverse transcription polymerase chain reaction method;
--- Increased the enzyme-linked immunosorbent assay method, replacing the indirect dot enzyme-linked immunosorbent assay protocol;
--- Revised the direct immunofluorescence test protocol, adopting NY/T 544-2015 "Diagnostic Techniques for Porcine Epidemic Diarrhea" 6.2
“Direct immunofluorescence method” and detailed description of its operation steps;
--- Revised the micro-sera neutralization test protocol, recommended cell lines, virus proliferation and toxic rate determination, control settings, etc.
The content has been revised and supplemented.

4 Overview of porcine epidemic diarrhea
Porcine epidemic diarrhea (PED) is a porcine epidemic diarrhea virus (PEDV) from Coronaviridae, Coronavirus
An acute highly exposed swine intestinal infectious disease with clinical manifestations of watery diarrhea, vomiting, dehydration, exercise stiffness and high death in suckling piglets
Characteristics such as death rate. Pigs of all ages can be infected, with lactating piglets at 1 week of age being the most susceptible. PEDV mainly through infected pigs
The spread of feces or other viral contaminants, under natural conditions, PEDV enters the pig's body through the oral and nasal routes. The prevalence of PED
