Abstract. Since April 2010, a severe outbreak of duck viral infection, with egg drop, feed uptake decline and ovary-oviduct disease, has spread around the major duck .
A new emerging flavivirus caused severe egg-drop in poultry and spread quickly across most duck-producing regions of China in 2010. During investigations into an outbreak of egg production decline, retarded growth, and even death among ducks in Southeast China, a novel Tembusu virus strain . Duck Tembusu virus (DTMUV) is an emerging pathogenic flavivirus that has resulted in large economic losses to the duck-rearing industry in China since 2010. .
The causative agent of this emerging disease was identified as the new duck Tembusu virus (DTMUV), a member of the Ntaya virus group in the genus Flavivirus (1,2). In addition to China, new DTMUV was recently detected among ducks in Malaysia . In Thailand, a severe contagious disease affecting ducks has newly emerged since 2013. The .china duck flavivirus disease An infectious disease of ducks caused by a newly emerged Duck Tembusu virus (DTMUV) is a member of the Ntaya antigenic group in the genus Flavivirus, family Flaviviridae.It has also been referred to as Baiyangdian virus (Su et al. 2011) and duck egg drop syndrome virus when it was isolated from diseased ducks. DTMUV has a nucleocapsid enclosed in a lipid bilayer envelope, and its .
Tembusu virus (TMUV, genus Flavivirus, family Flaviviridae) was first isolated in 1955 from Culex tritaeniorhynchus mosquitoes in Kuala Lumpur, Malaysia. . Sichuan Agricultural University, Chengdu, Sichuan 611130, PR China. 2 Key Laboratory of Animal Disease and Human Health of Sichuan . in the People's Republic of China. Since 2010, duck . A flavivirus-associated disease of egg-laying ducks was observed in eastern China in 2010, and a novel mosquito-borne flavivirus, Tembusu virus (TMUV), was isolated (Cao et al., 2011). Following up on the earlier study, a virus similar to TMUV was isolated recently from ducklings and characterized. .Duck egg-drop syndrome virus (DEDSV) is a newly emerging pathogenic flavivirus causing avian diseases in China. The infection occurs in laying ducks characterized by a severe drop in egg production with a fatality rate of 5–15 %. The virus was found to be most closely related to Tembusu virus (TMUV), an isolate from mosquitoes in South-east Asia.An infectious disease of ducks caused by a newly emerged Duck egg-drop syndrome virus (DEDSV) is a newly emerging pathogenic flavivirus causing avian diseases in China. The infection occurs in laying ducks characterized by a severe drop in egg production with a fatality rate of 5–15 %. The virus was found to be most closely related to Tembusu virus (TMUV), an isolate from mosquitoes in South-east Asia.In China in 2010, a disease outbreak in egg-laying ducks was associated with a flavivirus. The virus was isolated and partially sequenced. The isolate exhibited 87%–91% identity with strains of Tembusu virus, a mosquito-borne flavivirus of the Ntaya virus group. These findings demonstrate emergence of Tembusu virus in ducks.We report here the complete genomic sequence of the Chinese duck flavivirus TA strain. This work is the first to document the complete genomic sequence of this previously unknown duck flavivirus strain. The sequence will help further relevant epidemiological studies and extend our general knowledge of flaviviruses. . Poultry Diseases .
Duck egg drop syndrome virus (DEDSV) is a newly emerging pathogenic flavivirus isolated from ducks in China. DEDSV infection mainly results in severe egg drop syndrome in domestic poultry, which leads to huge economic losses. Thus, the discovery of ways and means to combat DEDSV is urgent. Since 2010, a remarkable amount of .Since April 2010, a novel contagious disease in ducks and geese, with egg drop, feed uptake decline and neurological signs, caused by a newly emerged virus has spread around Eastern China. . the causative agent of geese occurring in Eastern China is a new flavivirus. This is the first report that flavivirus infects not only egg-laying and .
The pathogenic flaviviruses include dengue, West Nile, and Japanese encephalitis viruses, and the nonpathogenic flaviviruses normally persist in a natural cycle and rarely cause disease in humans. A novel flavivirus, DTMUV (also known as duck egg drop syndrome flavivirus [DEDSV]) was identified in 2012 in ducks and then rapidly .
Virus propagation. The duck flavivirus HN strain was isolated from the liver of duck with egg-drop symptoms in China in 2010. Briefly, the liver was homogenized in PBS and then centrifuged at 1,000×g for 30 min at 4 °C. The supernatant was passed through a 0.2 μm filter (Whatman, Fisher Scientific, Norcross, GA) and inoculated into .
Avian tembusu-related virus, which was first identified in China, is an emerging virus causing serious economic loss to the Chinese poultry industry. We report here the complete genome sequences of avian tembusu-related virus strain WR, isolated from a White Kaiya duck with disease characterized by . In China in 2010, a disease outbreak in egg-laying ducks was associated with a flavivirus. The virus was isolated and partially sequenced. The isolate exhibited 87%–91% identity with strains of Tembusu virus, a mosquito-borne flavivirus of the Ntaya virus group. These findings demonstrate emergence of Tembusu virus in ducks.china duck flavivirus diseaseStarting in April 2010, a severe viral disease spread around the duck-producing regions in China, even in autumn when there is low or no mosquito activity in northern China. The affected ducks (including Pekin ducks, Muscovy ducks and domesticated mallards or Ma Ya) manifest a clinical symptom with heavy egg drop. OnHere we report the complete genomic sequence of Chinese duck flavivirus strain TA, which was isolated from a duck that showed obvious clinical signs of egg drop disease in Shandong Province, China, in 2010. Postmortem examination showed that the most obvious features of the duck are severe ovarian hemorrhage, ovaritis, and regression .
Tembusu virus (TMUV, genus Flavivirus, family Flaviviridae) was first isolated in 1955 from Culex tritaeniorhynchus mosquitoes in Kuala Lumpur, Malaysia. In April 2010, duck TMUV was first identified as the causative agent of egg-drop syndrome, characterized by a substantial decrease in egg laying and depression, growth retardation and neurological .
In China, since 2010, duck egg-drop disease has been reported in most duck-producing regions, including Beijing, Hebei, Shandong, Jiangsu, Anhui, Zhejiang . Feng L, Cao Y, Yang G, Jing C, Liang G, Wang H. Distribution and phylogenetic analysis of Culex flavivirus in mosquitoes in China. Arch Virol. 2015; 160:2259–2268. doi: .The CQW1 isolate proliferated in embryonated duck eggs and led to death within 3-4 days post-inoculation. Furthermore, CQW1 replicated in duck embryo fibroblast (DEF) cells and caused a cytopathic effect (CPE). The disease emerged on a duck farm in Southwest China and was reproduced by animal experiment.
