Phylogenetic study of the recent outbreak of Avian Influenza H5 subtype in Turkeys, Iran, 2019
Background: Global epizootic distribution of HPAI H5N8 (Clade 2.3.4.4) in poultry and wild birds was demonstrated after 2010. HPAI virus is a major concern not only in birds and poultry industry but also in global human health. Wild migratory birds and their linked to backyard birds are playing a critical role in spreading HPAI and the creation of genetic reassortment. Methods: In this study i...
متن کاملDevelopment of an immunochromatographic kit for rapid diagnosis of H5 avian influenza virus infection.
Highly pathogenic avian influenza (HPAI) caused by the H5N1 subtype has given rise to serious damage in poultry industries in Asia. The virus has expanded its geographical range to Europe and Africa, posing a great risk to human health as well. For the control of avian influenza, a rapid diagnosis by detecting the causative virus and identifying its subtype is essential. In the present study, a...
متن کاملH5 avian and H9 swine influenza virus haemagglutinin structures: possible origin of influenza subtypes.
There are 15 subtypes of influenza A virus (H1-H15), all of which are found in avian species. Three caused pandemics in the last century: H1 in 1918 (and 1977), H2 in 1957 and H3 in 1968. In 1997, an H5 avian virus and in 1999 an H9 virus caused outbreaks of respiratory disease in Hong Kong. We have determined the three-dimensional structures of the haemagglutinins (HAs) from H5 avian and H9 sw...
متن کاملRisk factors for seropositivity to H5 avian influenza virus in ostrich farms in the Western Cape Province, South Africa.
In a 2005 serological survey, carried out in response to an outbreak of H5N2 avian influenza (AI) in ostriches in the Eastern Cape Province, 16.3% of ostrich farms in the Western Cape Province of South Africa were found to be seropositive to H5 AI virus. We subsequently carried out a questionnaire-based census survey on all available registered Western Cape ostrich farms that still existed at t...
متن کاملSurveillance for highly pathogenic H5 avian influenza virus in synanthropic wildlife associated with poultry farms during an acute outbreak
In November 2014, a Eurasian strain H5N8 highly pathogenic avian influenza virus was detected in poultry in Canada. Introduced viruses were soon detected in the United States and within six months had spread to 21 states with more than 48 million poultry affected. In an effort to study potential mechanisms of spread of the Eurasian H5 virus, the United States Department of Agriculture coordinat...
