Viruses

Method of Detection

X-ray defraction, transmission electron microscopy and ultracentrifuge.
Typically attached to other larger partices, occurring within cells, or
are present in large conglomerate colonies. Often associated with
bacteria.

Fungi

Detected by electron microscopy, light microscopy and ultracenfrifuge. Large colonies visible to unaided eye. Sometimes associated
with mushroom spores or mycelium.

Detected by light microscopy. Large colonies visible to unaided eye.
Associated with a larger spore generating structure, often chain-like in
form.
