Sentences with phrase «found avian influenza»

Using a laboratory technique called real - time reverse transcription - PCR to examine the virus's genetic blueprint, they found avian influenza virus (AIV) genetic material in eight samples - six adult penguins and two chicks.

Not exact matches

The current H5N1 strain is a fast - mutating, highly pathogenic avian influenza virus (HPAI) found in multiple bird species.

Through the first three quarters of 2009, Indonesia failed to report any flu cases at all, even though the Food and Agriculture Organization (a body of the United Nations that monitors avian influenza in birds) has found the infection to be deeply entrenched among fowl in 31 of the country's 33 provinces and endemic in Java, Sumatra, and Bali.

A new study has found that a novel avian - origin H7N9 influenza A virus, which has recently emerged in humans, attaches moderately or abundantly to the epithelium of both the upper and lower respiratory tracts.

Using virus histochemical analysis, the investigators looked at the pattern of attachment of two genetically engineered emerging H7 viruses (containing the hemagglutinin (HA) of either influenza virus A / Shanghai / 1 / 13 or A / Anhui / 1 / 13) to fixed human respiratory tract tissues and compared the findings to attachment patterns seen with human influenza viruses with high transmissibility but low virulence (seasonal H3N2 and pandemic H1N1) and highly pathogenic avian influenza (HPAI) viruses with low transmissibility and high virulence (H5N1 and H7N7).

They found that like other avian influenza viruses, the H7N9 viruses attached more strongly to lower parts of the human respiratory tract than to upper parts.

In additional experiments, the scientists found that participants who had significant antibody responses did not necessarily also have significant immune system T cell responses to avian viruses, indicating that these two arms of immunity can be independently boosted after vaccination or infection; that individuals who reported receiving seasonal influenza vaccination had significantly higher antibodies to the avian H4, H5, H6, and H8 subtypes; and that participants with exposure to poultry had significantly higher antibody responses to the H7 subtype, but to none of the other subtypes tested.

The original H5N8 avian influenza strain was first found in South Korea in 2014 and subsequently in other Asian countries, including China and Japan, before spreading to Europe.

The human influenza virus H1N1 that caused the 2009 flu pandemic, and H9N2, an avian influenza virus that is endemic in bird populations in Asia, are close cousins — close enough that they can swap genes if they find themselves in the same cell, resulting in new viruses that are a patchwork of the parent strains.

While the highly - pathogenic H5N1 strain of avian influenza has yet to be discovered in the US, it is expected to be found here in the future.

Just last month we reported on a a new variant of the H5N1 strain of avian influenza (called H5N1 — 2.3.2.1) that was found in China and Vietnam.
