Can high-pathogenic avian influenza viruses with novel hemagglutinin serotypes other than H5 or H7 emerge?

Can high-pathogenic avian influenza viruses with novel hemagglutinin serotypes other than H5 or H7 emerge?

The family Herpesviridae is a large, diverse family of double-stranded enveloped DNA viruses. Herpes B virus (BV) and Cercopithecine herpesvirus 2 (CeHV-2) are simian herpesvi-ruses. Like herpes simplex virus 1 (HSV-1), they belong to the a-herpesvirus subfamily. interest in BV infections results from the observation that zoonotic infections often result in death of humans, whereas infection of...

Novel Eurasian Highly Pathogenic Avian Influenza A H5 Viruses

Susceptibility of swine to H5 and H7 low pathogenic avian influenza viruses

BACKGROUND The ability of pigs to become infected with low pathogenic avian influenza (LPAI) viruses and then generate mammalian adaptable influenza A viruses is difficult to determine. Yet, it is an important link to understanding any relationship between LPAI virus ecology and possible epidemics among swine and/or humans. OBJECTIVES Assess susceptibility of pigs to LPAI viruses found within...

Impact of avian influenza on U.S. poultry trade relations-2002: H5 or H7 low pathogenic avian influenza.

Avian influenza (AI) viruses are Type A influenza viruses of the Orthomyxoviridae family. There are 15 subtypes of the virus widespread in migratory waterfowl throughout the world. It has become increasingly evident that some low pathogenic avian influenza (LPAI) H5 or H7 viruses have the capacity to mutate into the more virulent strains that cause extensive economic losses and high mortality. ...

Immunization of Chickens with Newcastle Disease Virus Expressing H5 Hemagglutinin Protects against Highly Pathogenic H5N1 Avian Influenza Viruses

BACKGROUND Highly-pathogenic avian influenza virus (HPAIV) and Newcastle disease virus (NDV) are the two most important poultry viruses in the world. Natural low-virulence NDV strains have been used as vaccines over the past 70 years with proven track records. We have previously developed a reverse genetics system to produce low-virulent NDV vaccine strain LaSota from cloned cDNA. This system a...
