Highly pathogenic avian influenza virus subtype H5N1 in Mute swans in the Czech Republic

Veterinary Microbiology, 2007
In order to determine the actual prevalence of avian influenza viruses (AIV) in wild birds in the Czech Republic extensive surveillance was carried out between January and April 2006. A total of 2101 samples representing 61 bird species were examined for the presence of influenza A by using PCR, sequencing and cultivation on chicken embryos.

Quantum‐dots‐based fluoroimmunoassay for the rapid and sensitive detection of avian influenza virus subtype H5N1

Luminescence, 2010
AbstractThe continuous spread of highly pathogenic avian influenza virus (AIV) subtype H5N1 is threatening the poultry industry and human health worldwide. Rapid and sensitive diagnostic methods are required for the H5N1 surveillance. In this study, the fluorescent (FL) probe of CdTe quantum dots (QDs) was designed using covalently linked rabbit anti ...

Highly Pathogenic Avian Influenza Virus Subtype H5N1 in Mute Swans (Cygnus olor) in Central Bosnia

Avian Diseases, 2010
In order to determine the actual prevalence of avian influenza viruses (AIVs) in wild birds in Bosnia and Herzegovina, extensive surveillance was carried out between October 2005 and April 2006. A total of 394 samples representing 41 bird species were examined for the presence of influenza A virus using virus isolation in embryonated chicken eggs, PCR,

Isolation and characterization of influenza A virus (subtype H5N1) that caused the first highly pathogenic avian influenza outbreak in chicken in Bhutan

Veterinary Microbiology, 2012
We characterized Influenza A/H5N1 virus that caused the first outbreak of highly pathogenic avian influenza (HPAI) in chickens in Bhutan in 2010. The virus was highly virulent to chicken, killing them within two days of the experimental inoculation with an intravenous pathogenicity index (IVPI) of 2.88.

Global Occurrence and Spread of Highly Pathogenic Avian Influenza Virus of the Subtype H5N1

Avian Diseases Digest, 2011
Highly pathogenic avian influenza viruses of the subtype H5N1 (HPAIV-H5N1) have circulated continuously in Asia, Europe, and Africa since 2003. Investigations on the environmental preference and global spread processes of the virus are needed. We compiled 16 environmental variables to assess their correlation with HPAIV-H5N1 occurrences by using a ...

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 ...

Surveillance of influenza A virus subtype H5N1 in a live bird market in Yangon, Myanmar: 2017–2018

Transboundary and Emerging Diseases, 2020
A survey of influenza A viruses (IAVs) in the Mingalar Taung Nyunt live bird market (MTN-LBM), Yangon, Myanmar, was conducted from December 2017 to December 2018. During the survey, 455 swab samples were collected from broilers, layers, backyard chickens and ducks from the MTN-LBM.

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.

Rescue of H5N1 subtypeavian influenza A viruslethal to mice

Chinese Journal of Agricultural Biotechnology, 2007
AbstractAvian influenza virus is acquiring the ability to cross the species barrier between birds and mammals. However, the genetic mechanism of this ability is not well known. We successfully rescued aninfluenza A virusA/Chicken/Guangdong/03 (H5N1), which is highly pathogenic to both SPF chickens and BALB/c mice, by plasmid-based reverse genetics. The
