This study shows that high pathogenic H5N1 influenza virus infection of chicken induced high levels of bioactive interferon type I in the lung (4.3 × 10(5) U/mg tissue), plasma (1.1 × 10(5) U/mL), and spleen (9.1 × 10(5) U/mg tissue). In contrast, a low pathogenic attenuated H5N1 vaccine strain only induced approximately 24 times less IFN in the lung, 441 times less in the spleen and 649 less i...
background and aims: influenza virus nucleoprotein (np) has the capacity to be used as subunit vaccine, but little is known about the impact of different cultures on its structure. in the present study we aimed to evaluate and compare the isoelectric focusing (ief) property of extracted viral nucleoproteins derived from madin darby canine kidney (mdck) cell line and embryonated chicken eggs (ec...
The genome sequence of the strain A/chicken/Changzhou/C08/2013 (H9N9) shows that the hemagglutinin (HA) genes of this strain are closely related to those of the strain A/chicken/Shanghai/1107/2013 (H9N2) and share 99.2% nucleotide homology, while the other seven genes had the greatest sequence identities with the novel H7N9 virus. We speculate that this strain may be a novel natural reassortant...
Chicken anemia virus is commonly found in commercially produced chickens and has a worldwide distribution. It is difficult to inactivate thermally or with common disinfectants, which limits the utility of normal sanitization practices. The virus is important because of the disease it produces following transovarian transmission and because of its potential for inducing immunosuppression alone o...
The Central Australian public health network became aware of 2 cases of Murray Valley encephalitis during February to March, 2001. Both cases were noted following reports of MVE virus activity in sentinel chicken flocks throughout the Kimberley and Pilbara regions of Western Australia, similar activity in western New South Wales and evidence of sequential north-south spread of virus activity in...
Noninfectious hemagglutinins were prepared from the allantoic fluids of embryonated chicken eggs infected with Sindbis virus or with Murray Valley encephalitis virus.
A variant of Sindbis virus has been isolated by growing a stock of virus, previously passaged on chicken embryo cells, in mouse plasmacytoma (MOPC 315) cells in suspension culture. An indirect immunofluorescence test and infective center assay showed that only a small fraction of cells could be infected by the stock wild-type virus, but that the population of virus accumulating after a few pass...
