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.

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.

Understanding of Drug-Target Interactions: A case Study in Influenza Virus A Subtype H5N1

AIP Conference Proceedings, 2007
This study aims at gaining insight into molecular mechanisms of action of three drug targets of the life cycle of influenza virus A subtype H5N1, namely Hemagglutinin (H5), Neuraminidase (N1) and M2 ion channel (M2), using molecular mechanics and molecular dynamics techniques.

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

Characterisation and haemagglutinin gene epitope mapping of a variant strain of H5N1 subtype avian influenza virus

Veterinary Microbiology, 2013
H5N1 avian influenza virus (AIV) undergoes rapid evolution, and its antigenicity needs to be constantly evaluated in order to update the vaccine strain. In this report, a clade 7.2 AIV isolate named A/Chicken/Huadong/4/2008 (DT) is identified. Antigenic analysis revealed that DT had a significant low cross-reactive HI titre with antiserum against a ...

Susceptibility and transmissibility of pigeons to Asian lineage highly pathogenic avian influenza virus subtype H5N1

Avian Pathology, 2007
To determine whether or not pigeons are susceptible to infection with Asian lineage highly pathogenic (HP) avian influenza virus (AIV) subtype H5N1 and can serve as a transmission host for H5N1 HPAIV, we experimentally infected 187 young and adult pigeons with five different isolates of H5N1 HPAIV and co-habited some experimentally infected pigeons ...

Isolation and Identification of Highly Pathogenic Avian Influenza Virus Subtype H5N1 in Peafowl (Pavo cristatus)

Avian Diseases Digest, 2010
An outbreak of highly pathogenic avian influenza (HPAI) virus subtype H5N1 was first diagnosed in a "backyard" flock of peafowl (Pavo cristatus) raised on palace premises in the Kingdom of Saudi Arabia in December 3, 2007. The flock consisted of 40 peafowl, and their ages ranged from 3 to 5 years old.

[In vitro study of antiviral activity of Myramistin against subtypes H3N2 and H5N1 of influenza virus].

Antibiotiki i khimioterapiia = Antibiotics and chemoterapy [sic], 2009
In vitro antiviral effect of myramistin on influenza virus (MDCK cell culture) was studied. The drug showed significant dose-dependent antiviral activity against the virus. When used prophylactically (1 hour before exposure to the virus) in subtoxic doses, myramistin was effective in inhibiting replication of the influenza virus [strains A/Aichi/2/68 ...

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

Simultaneous detection of influenza virus type B and influenza A virus subtypes H1N1, H3N2, and H5N1 using multiplex real-time RT-PCR

Applied Microbiology and Biotechnology, 2011
Use of multiplex real-time reverse transcription polymerase chain reaction (RT-PCR) for the simultaneous detection of influenza type B virus and influenza A virus subtypes H5N1, H3N2, and H1N1 has been described. The method exhibited a high specificity and sensitivity of approximately 10(1)-10(2) copies per microliter or 10(-3)-10(-2) TCID50/L for each
