Hello, in this picture i have attached below, I am having a hard time determining if my unknown is either coccus or bacillus shaped. I used a gram stain by thr way which tested negative.

Bump

Where is it from?

Image is not good enough to tell for sure. What you saw directly is probably a better way to guess (i.e. whether majority are round or slightly elongated in one dimension). It also helps if you see them diffusing through the droplet for a little time as rods seen from the front can appear to be perfectly round, but reveal their shape when they start drifting.
