Influenza type A
- Ultrasensitive qualitative detection of influenza A virus by reverse transcription coupled real time polymerase chain reaction. This assay detects
but does not differentiate most known strains of influenza A viruses,
including H1N1, H2N2, H3N2, H3N8, H4N6,
H5N1, H5N2, H7N2, H7N7, H8N4 and H9N2.
a severe acute upper respiratory infection, and typical symptoms
include pyrexia, dyspnea, anorexia and coughing. Several
different subtypes and strains of influenza viruses infect
birds, humans, nonhuman primates and other mammals. Among these
different strains, the avian influenza viruses have been a major
concern. The natural reservoir for these viruses is wild birds,
and birds are only susceptible to influenza A viruses.
three prominent subtypes of avian influenza A virus. They are
classified by the hemagglutinin proteins on their surfaces: H5,
H7, and H9. These viruses can be further divided in “low
pathogenic avian influenza (LPAI)” and “high pathogenic avian
influenza (HPAI)” forms, depending on the severity of disease
they cause in birds.
Due to the
airborne nature of the disease, infection of one animal can
quickly spread to other animals and humans. Rapid and affordable
testing of suspected influenza cases is thus essential to
control the spreading of the disease. If the result of the rapid
immunoassay is negative but the animal exhibits symptoms of
respiratory infection, Zoologix also offers reflex PCR testing
of the same sample with much higher sensitivity, and for a
broader range of respiratory pathogens. This testing strategy
eliminates the delay and cost involved in redrawing and shipping

Contact Zoologix if advice is needed to determine an appropriate specimen type for a specific diagnostic application. For specimen types not listed here, please contact Zoologix to confirm specimen acceptability and shipping instructions. For all
specimen types, if there will be a delay in shipping, or during
very warm weather, refrigerate specimens until shipped and ship
with a cold pack unless more stringent shipping requirements are
specified. Frozen specimens should be shipped so as to remain
frozen in transit. See
shipping instructions for more information.
