The pathogenesis of duck virus enteritis in experimentally infected ducks: a quantitative time-course study using TaqMan polymerase chain reaction.
Duck virus enteritis is an acute and contagious herpesvirus infection of duck, geese and swans with high morbidity and mortality. The kinetics of viral DNA loads and immunohistochemical localization of virulent duck enteritis virus, as well as histopathological examination in various tissues of ducks following oral infection, were investigated. The time course for the appearance of viral antigen and tissue lesions in various tissues was coincident with the levels of duck enteritis virus at the various sites, suggesting that the levels of duck enteritis virus in systemic organs have a close correlation with the progression of disease. The abundance of target epithelial and lymphoid cells may contribute to the high levels of virus infection and replication in lymphoid and intestinal tissues.
