Avian paramyxoviruses type 1 or Newcastle disease viruses (NDV) are frequently recovered from wild birds and such isolates are most frequently of low virulence. Velogenic NDV are usually recovered from poultry and only occasionally from wild birds. Five NDV isolates were obtained from carcasses of four wild bird species during 2007 in Serbia: Mallard (Anas platyrhynchos), Eurasian Sparrowhawk (...

Surveillance for influenza A virus infection of seals has continued following the association of influenza A virus with epizootics of pneumonia in seals off the New England coast in 1979-1980 and 1982-1983. In January 1991 and January to February 1992, influenza A viruses were isolated from seals that died of pneumonia along the Cape Cod peninsula of Massachusetts. Antigenic characterization id...

Mallard (Anas platyrhynchos) duckling survival is an important, but not well understood, component of reproductive success for the species. To further investigate how mallard duckling survival is related to hatch date and wetland density, we analyze duckling counts for broods in southwestern Manitoba during the late 1980’s. Various models are explored to explain the patterns in the observed dat...

In this paper, we identify instances in which the auditor-client relationship has been terminated (i.e., the auditor resigns or the client dismisses the auditor) but the auditor continues to complete a subsequent quarterly review. Using discretionary accruals and earnings benchmark tests to proxy for the extent of earnings management, we contrast earnings management behavior during these “lame ...

Duck farming is on the raise in the current scenario, but processed products from duck meat are still uncommon to find. Investigating the duck meat qualities during storage will provide information to enhance duck meat utilization. Development of ready-to-eat and ready-to-cook duck meat products is expected to increase and improve non-chicken meat-based protein. The Study was aimed to evaluate ...

Climate change and other anthropogenic stressors affect freshwater ecosystems worldwide. A prominent manifestation of climate impacts on aquatic systems at high latitudes is the advance ice-out date (IOD). Earlier IOD should be advantageous for species such as migratory waterbirds that are dependent open water to initiate breeding; earlier breeding usually means higher reproductive success. How...

This study was carried out to compare the histomorphological structures of oviductal regions of the apparently healthy adult laying hens (Gallus gallus dometicus) and ducks (Ansa ansa domesticus). For this purpose, 20 hens and 20 female ducks aged between 1–1.5 years were used. After euthanasia, the oviducts were dissected out and all of the gross morphometrical parameters including length, wid...

Our overall hypothesis is that host population immunity directed at multiple antigens will influence the prevalence, diversity and evolution of influenza A virus (IAV) in avian populations where the vast subtype diversity is maintained. To investigate how initial infection influences the outcome of later infections with homologous or heterologous IAV subtypes and how viruses interact through ho...

Abstract— It has been found out that medicinal plants are potential sources of anticancer compounds. Thus, this study was conducted to evaluate the anti-angiogenic potential of the crude ethanolic extract from Insulin plant (Costus igneus) through chorioallantoic membrane (CAM) vascularity and teratogenicity assays in mallard duck (Anas platyrhynchos) embryos. Each of the seven treatments 5.0%,...
