Molecular epidemiology and genetic characteristics of pseudorabies virus between 2021 and 2023 in Henan Province of China.

ABSTRACT:

Importance

Pseudorabies (PR) is a significant disease that adversely affects the healthy growth of the pig industry in China. However, data on molecular epidemiology and genetic characterization of PRV is sparse.

Objective

This study examined the epidemic trends and variation characteristics of the PR virus (PRV) in Henan Province of China.

Methods

Six hundred eighty-eight clinically infected pig tissue samples were collected from 18 cities in Henan Province from January 2021 to March 2023 and tested for the PRV. The PRV was isolated from positive samples and identified by a polymerase chain reaction and immunofluorescence assay. The gB, gC, gD, and gE genes of the isolates were then amplified and sequenced for phylogenetic analysis. The
