Aspergillus
Aspergillus is an organism found ubiquitously in the environment.
Aspergillus is derived from the Latin word "Aspergere," which signifies
"to scatter".
In 1729, Micheli defined the genus Aspergillus. They are saprophytic
mold and are found in decaying organic matter.
They develop commonly as the molds on the substrate surface as the
contamination in the bread and potatoes.
In excess of 200 species of Aspergillus are found in nature, out of which
something like 20 species can cause human disease.
Out of these 20, the three most common pathogenic specialists in about
95 percent of the cases are Aspergillus flavus, A. fumigatus, and
Aspergillus niger.
Aspergillus spp. causes aspergillosis, a systemic fungal infection that
occurs both in the immunocompromised and the immunocompetent
individuals.
The sources of infection from the Aspergillus spp. are soil, air (inhalation
of spores), water/capacity tanks in hospitals, food, compost, decaying
vegetation, fireproofing materials, ventilation, air conditioning systems,
and computer fans. It exists as the mold structure as it were.
, Aspergillus has septate hyphae that structure the V-shaped dichotomous
branches.
The color of the colony on the culture media might be yellow, brown, or
black, depending upon the species and its development condition. There
are different species of Aspergillus.
They are
flavus
fumigatus
niger
terreus
glaucus
nidulans
oryzae
versicolor
clavatus
philaliseptus
