Aspergillus fumigatus fungus by real time polymerase
included in the poultry
includes several related fungi which cause aspergillosis. One
that is common in the environment is
This fungus produces airborne spores which can spread to a wide
area, especially during dry windy weather. Spores can enter and
develop in the respiratory system, lungs, eyes, and ears. “Sick
Building Syndrome” is a condition caused by continuous fungal
growth in areas of buildings and ventilation systems. Growth
leads to the release of more spores. This can potentially lead
to large scale respiratory infections and distress associated
aspergillosis are caused by endotoxins produced by the fungus.
Aspergillosis can be fatal, especially in immunodeficient
infection is common among domesticated and caged birds.
Animals such as birds, horses and
other livestock can be
infected with this fungus by inhalation of spores from
contaminated feed, fecal material, and soil. Healthy unstressed
birds and animals are generally resistant to even high
levels of spores. However, young and old individuals, those on
antibiotics, and those whose immune systems are suppressed by
surgery, reproduction, environmental changes, capture, or
shipping may become infected. Human patients with AIDS,
cancer or other immunosuppressive diseases are often victims of
this fungal infection.
birds and animals have had prior exposure to this fungus,
serological testing is not useful or reliable. Culture
identification is labor intensive and cultures are frequently
contaminated with other fungi. Molecular detection by PCR can
provide quick, sensitive and specific detection of the fungus in
a variety of specimen types (Buess et al., 2012).

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
