Dr. MacDonald,
Your reply and knowledge are much appreciated! Thank you for tips on focussing, I can’t wait to get even more amazed then I already am.
I will indeed not throw away possibilities of other strains of Babesia and keep on searching for a lab with a testkit for EU1 (and that’s also willing to cooperate), I live in the Netherlands.
Thank you for the points of extra care, I think they were all checked, but I will re-check at my friend to make sure. Also about air/water bubbles.
The smear was thin, with much care giemsa-prepared and it was far more then 30 minutes being 'eyeballed' under oil immersion.
I don’t have (access to) a phase contrast microscope to get sharper images. (unfortunately)
I don’t have a hamster or gerbil, but animal inoculation sounds nice to try and for getting some extra info.
I have a cat, likely has bartonella… I’m not sure, maybe his bacteremia surpasses mine…

but do you think if it can be of any use to try a drop of his blood to inoculate? Or is it only possible with hamsters and gerbils...
These extra pictures are from another smear, from a few weeks ago. This smear was thinner than the one before.
Platelets look purple, not grey.
Is this somewhat like what you mean by visible granules?
Babesia's blue ring and red dot, I’m not sure, looks like it, or more like purple and pink, but we will put another extra focus on it on our next smear in 3-6 months. (we’re both very sick and tired and it’s a lot of work doing it carefully (as you know), we can’t be busy with microscopy as much we’d want.)
I will look deeper into it. Thanks for helping out and
keeping me motivated.
I’m sorry if my english is with flaws.
