Dr Rick Speare from Tropical Solutions in Townsville Australia might be able to help

I don't think anybody can identify them on the basis of these pictures, certainly not as long as no multiplying forms are shown. And even then, one would need molecular tools.

Hi Ali. Its very tricky to id based on photos. Even to genus level. Although certainly you can say which ones are not (e.g. Trypanosomes...)

Can be Babesia but as Gerrit said, it needs more smears, better quality photos with different stages of the life cycle and sure for species id molecular study.

What type of rodents did you find these?

Hello everyone and thank you for comments

Host of them is Mus musculus

As other have said, it is very difficult to point at one intraerythrocytic parasite. But from experience, one may start thinking of a form of Babesia spp or a rickettsial if we know the stain used

Babesia

it can be Anaplasma spp.they are quite prevalent in some areas

It is very diffecult to point at one intraeritrocytic. I think they can be identified by molecular tools.

The images could correspond to ring forms of Babesia (probably Babesia microti, but also could be another small piroplasm). I do suggest a Giemsa stain and examine the slide trying to find maltese cross forms and if possible save the sample for molecular detection.  If you examine carefully the third slide a more definite but clear piroplasm appear to be at the right center bottom, below the arrow.
