Spiraling Organisms?
T490A Microscope
Ditch water
What are those tiny spiraling organisms in the center region of this video? I can't zoom any further without the 100X oil objective, and I dont really like that one. I want to get a 60X

Re: Spiraling Organisms?
I looked at the video twice, but I didn't see any spiraling organism.
Re: Spiraling Organisms?
I could just barely make them out. Judging by the magnification, I would guess spirochetes.

It is a very small object relative to the surrounding items in the visible environmentjanvangastel wrote: ↑Tue Mar 23, 2021 7:39 amI looked at the video twice, but I didn't see any spiraling organism.
Did you watch the video in Maximum resolution?

This is a spirillum. Spirochaetes are also helical in shape, but generally thinner with tight coils and actually move very differently, flexing as they go. Whereas spirilla are rigid and actually swim using tufts of flagella at the poles. Bacterial flagella work by turning, and this puts a torque on the cell causing it to rotate, and then the corkscrew shape takes advantage of that to give them a little extra propulsion. It's developed a number of times, mostly in different groups of Proteobacteria from what I can tell.

Re: Spiraling Organisms?
Thanks, I did now and I saw them. I wanted to compare them with what I saw some time ago (spirochetes), I think they are different: https://www.youtube.com/watch?v=MIOlmnPEdRUDid you watch the video in Maximum resolution?

Re: Spiraling Organisms?
Very hard to tell at this magnification and resolution. You can rule out spirochaetes. You need a really good high resolution 1000x phase contrast microscope to see these. Spirillum are much easier to see as they are much larger. You really need more magnification to see their beautiful corkscrew morphology. I probably have some images of both which I can post.
