Evolutionary dynamics of 2009 pandemic influenza A virus subtype H1N1 in South Africa during 2009-2010. [PDF]

The Journal of Infectious Diseases, 2012
The 2009 pandemic influenza A virus subtype H1N1 (A[H1N1]pdm09) was first detected in June 2009 in South Africa and later resulted in extensive transmission throughout Africa. Established routine surveillance programs and collaboration between private and public sector laboratories allowed for comprehensive molecular epidemiological and antigenic ...

Delayed 2009 pandemic influenza A virus subtype H1N1 circulation in West Africa, May 2009-April 2010. [PDF]

The Journal of Infectious Diseases, 2012
To understand 2009 pandemic influenza A virus subtype H1N1 (A[H1N1]pdm09) circulation in West Africa, we collected influenza surveillance data from ministries of health and influenza laboratories in 10 countries, including Cameroon, from 4 May 2009 through 3 April 2010. A total of 10,203 respiratory specimens were tested, of which 25% were positive for

Generation of a Reassortant Influenza A Subtype H3N2 Virus Expressing Gaussia Luciferase

Viruses, 2019
Reporter influenza A viruses (IAVs) carrying fluorescent or luminescent genes provide a powerful tool for both basic and translational research. Most reporter IAVs are based on the backbone of either subtype H1N1 viruses, A/Puerto Rico/8/1934 (PR8) or A ...

In silico modification of oseltamivir as neuraminidase inhibitor of influenza A virus subtype H1N1 [PDF]

The Journal of Biomedical Research, 2015
This research focused on the modification of the functional groups of oseltamivir as neuraminidase inhibitor against influenza A virus subtype H1N1. Interactions of three of the best ligands were evaluated in the hydrated state using molecular dynamics simulation at two different temperatures. The docking result showed that AD3BF2D ligand (N-[(1S,6R)-5-

Detection in 2009 of the Swine Origin Influenza A (H1N1) Virus by a Subtyping Microarray [PDF]

Journal of Clinical Microbiology, 2009
A novel H1N1 swine origin influenza A (IAV) virus (S-OIV) was discovered in specimens from two unrelated children in the San Diego area in mid-April 2009 (1, 2). Those samples were positive for IAV but negative for both human H1 and H3 subtypes. The outbreak evolved rapidly, and the World Health Organization (WHO) declared the highest phase 6 worldwide

Development of DNA-Biochip for Identification of Influenza A Virus Subtypes

Проблемы особо опасных инфекций, 2012
Developed was the DNA-biochip to identify subtypes of influenza A virus, pathogenic for humans. Microchip was capable of detecting H1, H3, H5-subtypes of hemagglutinin (including H1-subtype of pandemic A/H1N1(2009) influenza virus ) and neuraminidase ...
