Primary cultures of intrahepatic bile duct epithelial (IBDE) cells isolated from duckling livers were successfully grown for studies of duck hepatitis B virus (DHBV). The primary IBDE cells were characterized by immunohistochemistry using CAM 5.2, a cytokeratin marker which was shown to react specifically to IBDE cells in duck liver tissue sections and in primary cultures of total duck liver ce...

In India, the contribution of ducks for egg and meat production is next to chicken. There are many advantagesof duck over The important available in country few exotic breeds locallyavailable indigenous ducks. Ducks can be reared under intensive, semi-intensive extensive rearing system.However, mostly small flock size as subsidiary source income. major basedintegrated farming system duck-fish, ...

Duck plague virus (DPV), a member of alphaherpesvirus sub-family, can cause significant economic losses on duck farms in China. DPV Chinese virulent strain (CHv) is highly pathogenic and could induce massive ducks death. Attenuated DPV vaccines (CHa) have been put into service against duck plague with billions of doses in China each year. Researches on DPV have been development for many years, ...

The present study was conducted on each of the three adult birds of Emu and Duck procured from the farms located in and around Gannavaram. The renal parenchyma of Emu and Duck was divided into large cortical lobules and smaller medullary lobules/cones. The renal cortex of both the birds showed a labyrinth of tubules and renal corpuscles. Small loopless cortical (reptilian type) nephrons and lar...

To study whether influenza virus receptors in chickens differ from those in other species, we compared the binding of lectins and influenza viruses with known receptor specificity to cell membranes and gangliosides from epithelial tissues of ducks, chickens, and African green monkeys. We found that chicken cells contained Neu5Ac alpha(2-6)Gal-terminated receptors recognized by Sambucus nigra le...

A novel duck circovirus (DuCV) strain, designated GH01, was isolated from ducklings in southwestern China. We report the genome sequence of GH01 and the genomic organization and genetic relationship to other DuCVs. The availability of the genome sequence will be helpful to investigations of epidemiology and the evolutionary biology of this organism and the development of preventive vaccines.

The duck plague vaccine (DPV) is locally produced from the Livestock Research Institute (LRI), Mohakhali, Dhaka which is used to control the duck plague viral disease in ducks in Bangladesh. Efficacy of this vaccine reports has no, so to say on ducks in Bangladesh. Three weeks old 50 Khaki Cambell Ducks were used to evaluate the induced of immune responses of duck plague vaccine during the peri...

VLDLR gene was chosen as a candidate gene infl uencing abdominal fat trait and body weight due to previous studies in human and mouse. Herein, the objectives of this study were to identify genetic polymorphisms of duck VLDLR gene, and to analyze association between combined haplotypes and abdominal fat trait in Gaoyou domestic duck. A total of 207 individuals, including the elite reservation fa...

Melanoma differentiation-associated gene 5 (MDA5) is an important intracellular receptor that recognizes long molecules of viral double-stranded RNA in innate immunity. To understand the mechanism of duck MDA5-mediated innate immunity, we cloned the MDA5 cDNA from the Muscovy duck (Cairina moschata). Quantitative real-time PCR analysis indicates that duck MDA5 mRNA was constitutively expressed ...

4,4'-Dinitrocarbanilide (DNC) was extracted from chicken, duck, goose, and snake eggs and isolated by reversed-phase liquid chromatography. DNC was detected by ultraviolet absorbance at 347 nm and quantitated by comparison with a calibration standard. Recoveries of DNC from fortified control chicken, duck, goose, and snake egg samples were determined for DNC levels of 0.16, 10, and 16 microg/g....
