Effect of age on the pathogenesis of duck tembusu virus in Cherry Valley ducks
The effect of host age on the outcome of duck tembusu virus (DTMUV) infection was studied in ducks. Three groups of Cherry Valley ducks at 1, 3, and 7 weeks of age were intramuscularly infected with DTMUV to systematically observe the clinical symptoms, pathological changes, tissue viral loads, and immune responses. Severe clinical symptoms and neurological dysfunction were observed in 1-week-o...
متن کاملPathogenicity of duck plague and innate immune responses of the Cherry Valley ducks to duck plague virus
Duck plague caused by duck plague virus (DPV) is an acute and contagious disease. To better understand the pathogenic mechanism of duck plague virus in ducklings, an infection experiment was performed. Our results showed that typical symptoms were observed in the infected ducklings. DPV could replicate quickly in many tissues, leading to pathological lesions, especially on the spleen. Real-time...
متن کاملDiagnosis and characterization of duck beak atrophy and dwarfism syndrome in Chongqing of China

In October 2017, an unidentified disease occurred in Cherry Valley ducks, Chongqing municipality, the southwest of China. The affected birds showed short beak and growth retardation clinical signs. The disease caused approximately 20.00% morbidity and serious weight loss due to retarded growth. In ord...
متن کاملComplete genome sequence of the novel duck hepatitis B virus strain SCP01 from Sichuan Cherry Valley duck
BACKGROUND The duck hepatitis B virus (DHBV) strain, designated SCP01, was isolated and identified from a Sichuan Cherry Valley duck in Southwestern China. To determine the origination and evolution of this isolated strain, we carried out complete genome sequencing of this strain. FINDINGS Sequencing of the nucleotide sequence of DHBV strain SCP01 revealed a genome size of 3021 bp that contai...
متن کاملMolecular detection and characterization of beak and feather disease virus in psittacine birds in Tehran, Iran
Beak and feather disease virus (BFDV), a member of genus circovirus, is a small, non-enveloped, single stranded DNA virus. Although BFDVs are among the most well studied circoviruses, there is little to no information about BFDVs in Iran. The aim of the present study was to detect and identify BFDV molecules from the birds referred to the avian clinic of The Faculty of Veterinary Medicine, Tehr...
