Influenza virus serology—a comparative study

Journal of Virological Methods, 1999
Virus isolation or influenza virus antigen detection are the most rapid tests for diagnosis in the acute stage of influenza virus infection. As serology is easier to carry out, the synthesis of serum IgM, IgA and IgG was studied in two well-defined patient groups, infected with influenza B virus (cohort 1, n = 37) and influenza A virus (cohort 2, n ...

Influenza Virus: a Master of Metamorphosis

Journal of Infection, 2000
Novel influenza viruses continuously emerge in the human population. Three times during the present century, an avian influenza virus subtype crossed the species barrier, starting a pandemic, and establishing itself for one to several decades in man. As the 1997 H5N1 event in Hong Kong indicated, the occurrence of another pandemic in the near future ...

Human influenza A H5N1 virus related to a highly pathogenic avian influenza virus

The Lancet, 1998
In May, 1997, a 3-year-old boy in Hong Kong was admitted to the hospital and subsequently died from influenza pneumonia, acute respiratory distress syndrome, Reye's syndrome, multiorgan failure, and disseminated intravascular coagulation. An influenza A H5N1 virus was isolated from a tracheal aspirate of the boy.

Avian Influenza A H5N1 Virus

Clinics in Laboratory Medicine, 2010
Although influenza A viruses of avian origin have long been responsible for influenza pandemics, including the "Spanish flu" pandemic of 1918, human infections caused by avian subtypes of influenza A virus, most notably H5N1, have emerged since the 1990s (H5N1 in 1997; H9N2 in 1999; and H7N7 in 2003).

Neurovirulence of influenza A virus

Journal of Neurovirology, 1996
Infection of mouse brain with influenza A virus has provided a valuable model for investigating viral adaptation and virulence. These studies have indicated important roles for the neuraminidase (NA), matrix (M), non-structural (NS) and haemagglutinin (HA) genes of the virus in determining neurovirulence.

Influenza Virus A H5N1 (“Avian Influenza”)

2010
A nasal pharyngeal aspirate (NPA) is the specimen of choice for exclusion of influenza H5 strains in young children while a nasopharyngeal swab may be easier to obtain for older children and adults. Swabs should be collected and transported in the primary collection container containing viral transport medium (VTM).

Equine influenza — A segment in influenza virus ecology

Comparative Immunology, Microbiology and Infectious Diseases, 1980
Abstract Influenza viruses Heq1 Neq1 and Heq2 Neq2 are the only viruses responsible for equine influenza. Properties of both subtypes Heq1 Neq1 and Heq2 Neq2 are studied as well as their experimental pathogenecity and immune response in different species such as mouse, piglet and primates. Their antigenetic aspect and ecology are studied.

Influenza A virus-induced apoptosis and virus propagation

Apoptosis, 2019
Influenza A viruses (IAVs) are respiratory pathogens that cause severe morbidity and mortality worldwide. They affect cellular processes such as proliferation, protein synthesis, autophagy, and apoptosis. Although apoptosis is considered an innate cellular response to invading infectious pathogens, IAVs have evolved to encode viral proteins that ...

Hemagglutination by Influenza Virus: III. The Xo Phase of Influenza A Virus

Journal of Infectious Diseases, 1948
In the original characterization of the O-D change in influenza virus, type A, Burnet and Bull1 stated that they found no evidence of a change from the D to the O phase, but that the O phase could be transformed by a process of discontinuous mutation to the D phase.

Wilmot virus a new influenza A virus infecting turkeys

Archiv f�r die gesamte Virusforschung, 1966
A hemagglutinating virus, recently isolated from the respiratory tract of turkeys, has been characterized and classified in the influenza A virus group. Wilmot virus can be considered a new serotype of this group, since it was found to be serologically distinct from the known influenza A viruses, which infect birds and mammals.
