In 1985, a 0.5-mm cell was discovered in surgeonfish and named
Epulopiscium fishelsoni. It was presumed
to be a protozoan. In 1993, researchers determined that
Epulopiscium was actually a gram-positive bacterium.Why do you
suppose this organism was initially identified as a protozoan?
What evidence would change the classification to bacterium?
I don’t know would it be the shape and whether it shows up to be gram positive in a test?
Probably because it
1. Is gigantic for a bacterial cell.
2. Has strange morphological features, like invaginations, vesicles, and tubules.
3. Reproduces strangely.
It was found to be bacterial after rRNA sequencing.
