Presence of Vaccine-Derived Newcastle Disease Viruses in Wild Birds
Our study demonstrates the repeated isolation of vaccine-derived Newcastle disease viruses from different species of wild birds across four continents from 1997 through 2014. The data indicate that at least 17 species from ten avian orders occupying different habitats excrete vaccine-derived Newcastle disease viruses. The most frequently reported isolates were detected among individuals in the ...
متن کاملNewcastle Disease and Avian Influenza A Virus in Migratory Birds in Wetland of Boushehr-Iran
Wild birds are considered to be the natural reservoir of Newcastle Disease Virus (NDV) and Avian Influenza virus (AI) and are often suspected to be involved in outbreaks in domesticated birds. The objective of the present study was to determine ND and AI infection in migratory birds in the south of Iran in order to detect the possible source of these viruses to domestic poultry. A total of 443 ...
متن کاملEndoparasite Infections in Pet and Zoo Birds in Italy
Faecal samples were individually collected from pet (n = 63) and zoo (n = 83) birds representing 14 orders and 63 species. All the samples were examined by faecal flotation technique. In a subgroup of samples (n = 75), molecular assays were also used to detect Cryptosporidium oocysts and Giardia duodenalis cysts. Overall, 35.6% of the birds harboured parasites (42.2% of zoo birds and 27% of pet...
متن کاملPrevalence of infectious bronchitis and Newcastle disease virus among domestic and wild birds in H5N1 outbreaks areas.
INTRODUCTION The first H5N1 outbreak in Burkina Faso was reported to the World Organization for Animal Health on 3 April 2006.

متن کاملMolecular characterization of haemagglutinin-neuraminidase gene among virulent Newcastle disease viruses isolated in Iran
Background: Virulent Newcastle disease virus (vNDV) causes great economic losses to the poultry industry throughout the world. Despite the endemicity of Newcastle disease (ND) and occurrence of recurrent outbreaks, the nature and genetic features of circulating NDV strains in Iran are largely unknown. Aims: This study was conducted to characterize 13 NDV isolat...
