Systemic infection of avian influenza A virus H5N1 subtype in humans

open access: yesHuman Pathology, 2009
The viral dissemination in a patient with avian influenza A subtype H5N1 infection was retrospectively studied by the immunohistochemical localization of viral nucleoprotein antigen. The pathology was marked by diffuse alveolar damage, lymphoid depletion, and reactive hemophagocytic syndrome.

Development of ssDNA Aptamers for Diagnosis and Inhibition of the Highly Pathogenic Avian Influenza Virus Subtype H5N1 [PDF]

open access: yesBiomolecules, 2020
Avian influenza (AI) has severely affected the poultry industry worldwide and has caused the deaths of millions of birds. Highly pathogenic avian influenza virus is characterized by high mortality and the ability to transmit from birds to humans. Early diagnosis is difficult because of the variation in pathogenicity and the genetic diversity between ...

Isolation and characterization of highly pathogenic avian influenza virus subtype H5N1 from donkeys [PDF]

open access: yesJournal of Biomedical Science, 2010
The highly pathogenic H5N1 is a major avian pathogen that crosses species barriers and seriously affects humans as well as some mammals. It mutates in an intensified manner and is considered a potential candidate for the possible next pandemic with all the catastrophic consequences.Nasal swabs were collected from donkeys suffered from respiratory ...

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 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.

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 ...

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.
