Monitoring and Evaluation of Porcine Pseudorabies in Henan Province from 2020 to 2022
To understand the situation of pig pseudorabies virus infection in Henan Province and continue to promote the purification of pig pseudorabies,the Henan Provincial Center for Animal Disease Prevention and Control conducted testing through the monitoring program,and compared and analyzed the data from 2020 to 2022.A total of 34506 pig serum samples and 10,589 pathogenic samples were collected.ELISA method was used to detect the infection antibody of porcine Pseudorabies gpI(gE)serum.Fluorescent PCR was used to detect the etiological samples,and the detection results were statistically analyzed.The results showed as follows:From 2020 to 2022,the average individual positive rate of PRV gE antibody in pigs in Henan Province was 20.30％,15.76％,11.01％,and the average field positive rate was 52.77％,35.35％,27.80％,respectively.From 2020 to 2022,the average individual positive rate of breeding farms,commodity farms,and slaughterhouses was 10.62％,20.10％,and 16.79％,respectively,and the average positive rate of farm groups was 31.72％,45.27％,and 33.19％,respectively.From 2020 to 2022,the average individual positive rate and the average field positive rate were in central Henan,Eastern Henan,Western Henan,Southern Henan,and Northern Henan in order from high to low.The highest individual positive rate was 22.56％,the lowest was 13.12％,the highest positive rate was 52.4％and the lowest positive rate was 31.4％.From 2020 to 2022,the average individual positive rate and the field positive rate decreased successively.It can be seen that the positive rate of antibodies and etiology of swine pseudorabies virus infection in Henan province decreased year by year,and the purification effect was obvious.
