摘要： Pseudorabies virus (PRV), the causative agent of Aujeszky's disease, has gained increased attention in China in recent years as a result of a recent outbreak of pseudorabies. The causative agent has a wide spectrum of hosts, including pigs, cattle, sheep, dogs, cats, bats, bears, and even some avian species. Although dog-related cases of pseudorabies have been reported regularly, many cases are overlooked, and few PRV strains are isolated because death occurs rapidly after PRV infection and veterinarians often do not test for PRV in dogs. Here, we performed a retrospective detection of PRV in dogs from July 2017 to December 2018. We found that PRV (includinggE-deleted strains, classical strains, and variant strains) is prevalent in dogs regardless of season and region and that the epidemic PRV strains in dogs share high sequence similarity withgCandgEgenes of swine epidemic strains and commercial vaccine strains. Collectively, our findings underscore the importance of PRV surveillance in dogs, which is beneficial for understanding the epidemiology of PRV in dogs and assists in efforts aimed at effectively controlling this disease.
