Structural changes in the liver of mice infected with avian influenza virus subtype H5N1

Bulletin of Experimental Biology and Medicine, 2008
Intranasal infection of male outbred rats with isolate of influenza A virus subtype H5N1 (A/Gs/Krasnoozerskoye/627/05) from the Novosibirsk region was followed by high mortality of experimental animals. Morphological study of liver samples revealed subtotal destructive changes in the liver parenchyma (proteinosis and centrolobular necroses), which was ...

Experimental Assessment of Houseflies as Vectors in Avian Influenza Subtype H5N1 Transmission in Chickens

Avian Diseases, 2013
In this study, laboratory-reared houseflies were experimentally exposed to the high pathogenicity avian influenza virus (HPAI) subtype H5N1 virus to evaluate the houseflies as vectors in HPAI-H5N1 virus transmission in chickens. One hundred and fifty houseflies (Musca domestica L.) were equally allocated into three groups.

[Establishment of reverse genetics system for H5N1 subtype AI].

Wei sheng wu xue bao = Acta microbiologica Sinica, 2009
H5N1 subtype influenza virus A/Duck/Shandong/093/2004 (A/SD/04) strain was chosen as the master strain for rescue research. 11 sets of primers for 8 plasmids construction were designed base on the sequencing of the full-length of A/SD/04. Eleven fragments of A/SD/04 were amplified by the designed primers and were ligated with PHW2000 for rescue plasmid

Surveillance on Avian Influenza H5N1 and H9N2 Subtypes In Egypt 2012-2013

Poultry, Fisheries & Wildlife Sciences, 2014
Surveillance on Avian Influenza Virus in Egypt during 2012 - 2013 was undertaken to update the epidemiology of avian influenza virus infections among poultry flocks in Egypt. A total of 148 commercial chicken farms were tested by single-plex RT-PCR for direct detection of avian influenza viruses using type A specific nucleoprotein (NP) gene primer sets.

[Inhibition of proliferation of H5N1 subtype AIV in CEF by chemosynthetic siRNA].

Bing du xue bao = Chinese journal of virology, 2014
In order to study the proliferation inhibition effect of H5N1 subtype avian influenza virus (AIV) with small interfere RNA (siRNA), a total of 4 siRNAs were designed in accordance with the NP and PA genes of H5N1 subtype AIV, the siRNAs were then transfected to chicken embryo fibroblast(CEF), CEF was infected with H5N1 subtype AIV after 6 hrs.

The spread of highly pathogenic avian influenza (subtype H5N1) clades in Bangladesh, 2010 and 2011

Preventive Veterinary Medicine, 2014
Since the global spread of highly pathogenic avian influenza H5N1 during 2005-2006, control programs have been successfully implemented in most affected countries. HPAI H5N1 was first reported in Bangladesh in 2007, and since then 546 outbreaks have been reported to the OIE. The disease has apparently become endemic in Bangladesh.

Infection of Thai Influenza A Viruses Subtype H5N1 Using Tracheal Culture

The Thai Journal of Veterinary Medicine, 2015
Avian influenza (AI) is caused by influenza A virus subtype H5N1. The virus causes severe disease and death in several avian and mammalian species. This study investigated the ability of swine and chicken tracheal cultures to support highly pathogenic avian influenza subtype H5N1 (HPAI-H5N1) viral replication. Three Thai HPAI-H5N1 viruses isolated from

Highly pathogenic avian influenza virus subtype H5N1 in ducks in the Northern part of Cameroon

Veterinary Microbiology, 2008
Highly pathogenic avian influenza (HPAI) virus was first detected in Cameroon in February 2006. Analysis of NA sequences of the virus demonstrated that it is closely related to the H5N1 isolates from Northern Nigeria, Sudan and Ivory Coast, suggesting a common virus ancestor.

Rapid detection of the avian influenza virus H5N1 subtype in Egypt

2016
Influenza A virus continue to cause widespread morbidity and mortality. The unprecedented spread of highly pathogenic avian influenza virus subtype H5N1 in Egypt is threatening poultry and public health systems. Effective diagnosis and control management are needed to control the disease. To this end, polyclonal antibodies (PAbs) were developed against
