Aspergillus is best described by which of the following statements?
High-Yield Explanation
Aspergillosis, caused by a number of species of Aspergillus, is characterized in direct smear by septate hyphae, dichotomously branched. A. flavus and A. fumigatus are often seen as saprophytes in the laboratory but also account for the major species isolated from patients with aspergillosis. Differentiation of species, as with the Zygomycetes, is dependent upon isolation of the fungus and precise morphological examination.
