Bicosoeca lacustris

Here is a foto of a colorless, housing-resident flagellate belonging to the Chrysophyceae. It is probabely Bicosoeca (synonym Bicoeca), through the elongated elliptical case it could be Bicosoeca lacustris. https://en.wikipedia.org/wiki/Bicosoeca http://www.kasviplanktonopas.net/uusin/lajisto/suku.p...

Haematococcus pluvialis has various "faces". I wonder what stages you have observerd. Pls. feel free to share! Does anybody have seen stages "c" and "h" - see fig. 1 below? The development cycle of Haematococcus pluvialis is represented as followed (according to ELLIOT, see also footnote 1): Fig. 1:...

Re: New acquisition- Leitz diaplan

Congratulations einman. Nice microscopes. I am not a Leitz expert, so on questions: The mico on the right hand has a kind of intermediate tube. What exacetely is the use of this? Is it for Analysator slide or is it to change magnification, maybe like the optovar usded by Zeiss?

Thanks Jim. Zackenkrone Radertierchen is German and maybe translate as "prong crown". I somehow like these vernacular names since I usually cannot remember the latin names ;)

Re: Trypanosoma gambiense (sleeping sickness)

I was interested to find out Robert Koch was a pioneer in photomicrography. He published a paper in 1877 with the first photomicrographs of anthrax bacilli. In 1877, he was most likely using the wet plate photographic process. I wonder if the equipment he used has survived in a museum or collection...

Re: Rotifier - Phase contrast

Could I ask, what power objective did you use, and what phase system did you use (eg. bright phase, dark phase, or something in between)? It was the Carl Zeiss Phase contrast using the Planachro 16/0,35 with the PH2 orifice. Was somehow surprised not to get much halos. As always I used my IM35 with...
