I making some research, about effects of household antibacterial regents on bacterial colonies. So I grow bacterias from desk before regent was used and after. And problem that my stupid head thought let use grama staining method, now I have 8 photos from microscope and I need compere number of bacterias from each sample. Can someone can recommend program or method how count cells and give some tips how next time don’t make similar mistake, recommend methods to count cells (I don’t have expensive lab technologies).

Can I somehow adapt this man's program?
