I could not find the piece of information form Burton Human Parasitology -book and not by Google. Yeast is divided to two phylums: one of them is Ascomycota. Aspergillus clavatus belong to the given phylum. Yeast is unicellular. So it is possible that Aspergillus clavatus is unicellular.
Can you tell whether the Aspergillus clavatus is an unicellular orgarism or not from the following picture?
I need to find unicellular parasites that cause damage of brain. The fungus causes patulin so hemorrhaging of brain, but should still be unicellular to meet the criteria.
