| pathology of fatal highly pathogenic h5n1 avian influenza virus infection in large-billed crows (corvus macrorhynchos) during the 2004 outbreak in japan. | highly pathogenic h5n1 avian influenza viruses were isolated in 9 large-billed crows that died in kyoto and osaka prefectures in japan from march to april in 2004. we studied 3 of the 9 crows using standard histologic methods, immunohistochemistry, and virus isolation. the most prominent lesions were gross patchy areas of reddish discoloration in the pancreas. the consistent histologic lesions included severe multifocal necrotizing pancreatitis, focal degeneration and necrosis of neuron and glia ... | 2006 | 16846992 |
| isolation and molecular characterization of a h5n1 virus isolated from a jungle crow (corvus macrohynchos) in india. | in 2008, india experienced widespread outbreaks of h5n1 virus in west bengal, tripura, and assam. the virus was detected in kamrup district of assam in november 2008 and subsequently spread to eight more districts. two jungle or large billed crows (corvus macrohynchos) were found dead in a hospital campus at about 8 km from the foci of initial detection of the virus in the same district. one of the crows was positive for h5n1 avian influenza virus by virus isolation, real time rt-pcr, and rt-pcr ... | 2010 | 20396941 |
| analysis of the crow lung transcriptome in response to infection with highly pathogenic h5n1 avian influenza virus. | the highly pathogenic avian influenza (hpai) h5n1 virus, currently circulating in asia, causes severe disease in domestic poultry as well as wild birds like crow. however, the molecular pathogenesis of hpaiv infection in crows and other wild birds is not well known. thus, as a step to explore it, a comprehensive global gene expression analysis was performed on crow lungs, infected with hpai h5n1 crow isolate (a/crow/india/11ti11/2011) using high throughput next generation sequencing (ngs) (gs fl ... | 2015 | 25592823 |
| experimental infection of highly and low pathogenic avian influenza viruses to chickens, ducks, tree sparrows, jungle crows, and black rats for the evaluation of their roles in virus transmission. | highly pathogenic avian influenza viruses (hpaivs) have spread in both poultry and wild birds. determining transmission routes of these viruses during an outbreak is essential for the control of avian influenza. it has been widely postulated that migratory ducks play crucial roles in the widespread dissemination of hpaivs in poultry by carrying viruses along with their migrations; however close contacts between wild migratory ducks and poultry are less likely in modern industrial poultry farming ... | 2016 | 26711036 |
