“…DVE replicates in epithelial cells (Tantaswasdi et al, 1988;Barr et al, 1992) and, given its alpha herpesvirus nature, produces ICIBs composed of large clusters of virions (Kaleta, 1990;Barr et al, 1992). These features have also been observed in our study.…”

Duck virus enteritis is an acute contagious viral disease affecting birds of the order Anseriformes (ducks, geese and swans). The disease agent is a member of the Herpesviridae family (Anatidae herpes virus 1). A group of Anseriformes waterfowl from a Nature Reserve and Centre for the Recovery of Endangered Species in Spain suffered an outbreak of the disease, affecting adults, young and newborns. Other non-Anseriformes waterfowl such as coots, from the family Rallidae, order Gruiformes, were also affected.Histopathological and ultrastructural findings confirmed the viral infection. The present study provides evidence that birds different from the order Anseriformes can be affected, suggesting that the virus has the ability to infest other non-Anseriformes waterfows.

“…Diagnosis can be strengthened by demonstration of intra-nuclear inclusion bodies in epithelial cells of the digestive, respiratory and reproductive tracts, liver and spleen (Tantaswasdi et al 1988;Shawky et al 2000;Campagnolo et al 2001). The presence of DVE can also be confirmed by demonstration of the virus in tissues through FATs (Tantaswasdi et al 1988). Molecular studies and sequencing indicated close ancestry between Bangladeshi and Chinese isolates of DPV (Ahamed et al 2015).…”

“…Using electron microscopy, they also demonstrated membrane-bound intra-cytoplasmic inclusions which contained enveloped herpes virus and nuclei containing herpes viral nucleocapsids. Replication and growth curves of DEV were studied in cell cultures by electron microscope (Breese & Dardiri 1968;Bergmann & Kinder 1982;Tantaswasdi et al 1988;He et al 2012). The virus replicates mainly in the mucosal epithelial cells of the gastrointestinal tract, especially in the epithelial cells of the esophagus, and then disseminates into the thymus, bursa of Fabricius, spleen and liver in a susceptible host (Islam & Khan 1995;Shawky & Schat 2002).…”

“…Microscopic findings include necrosis of epithelial lining of the digestive tract together with infiltration of variable lymphocyte and macrophage numbers within mucosal and serosal connective tissues. Eosinophilic intra-nuclear and cytoplasmic inclusions have been seen in epithelial cells of the digestive, respiratory and reproductive tracts as well as in visceral organs such as liver and spleen (Tantaswasdi et al 1988;Shawky et al 2000;Campagnolo et al 2001;Konch et al 2009). The affected epithelium becomes edematous, necrotic and rose into the lumen above normal adjacent mucosal surfaces.…”

Duck virus enteritis (DVE), also called duck plague, is one of the major contagious and fatal diseases of ducks, geese and swan. It is caused by duck enteritis virus (DEV)/Anatid herpesvirus-1 of the genus Mardivirus, family Herpesviridae, and subfamily Alpha-herpesvirinae. Of note, DVE has worldwide distribution, wherein migratory waterfowl plays a crucial role in its transmission within and between continents. Furthermore, horizontal and/ or vertical transmission plays a significant role in disease spread through oral-fecal discharges. Either of sexes from varying age groups of ducks is vulnerable to DVE. The disease is characterized by sudden death, vascular damage and subsequent internal hemorrhage, lesions in lymphoid organs, digestive mucosal eruptions, severe diarrhea and degenerative lesions in parenchymatous organs. Huge economic losses are connected with acute nature of the disease, increased morbidity and mortality (5%-100%), condemnations of carcasses, decreased egg production and hatchability. Although clinical manifestations and histopathology can provide preliminary diagnosis, the confirmatory diagnosis involves virus isolation and detection using serological and molecular tests. For prophylaxis, both live-attenuated and killed vaccines are being used in broiler and breeder ducks above 2 weeks of age. Since DEV is capable of becoming latent as well as shed intermittently, recombinant subunit and DNA vaccines either alone or in combination (polyvalent) are being targeted for its benign prevention. This review describes DEV, epidemiology, transmission, the disease (DVE), pathogenesis, and advances in diagnosis, vaccination and antiviral agents/therapies along with appropriate prevention and control strategies.
