Did you clean the slide and coverslip before using them? Either, or both look contaminated to me.
Hope this helps.
to be honest, i only cleaned the slide, but i used new coverslip because i have so plenty of it, wasn't doing things serious so didn't want to through slides too, i still have a lot, but i want to have serious samples or specimen then i will start to use completely new slides and coverslips.
Do not rely on the new slides and coverslips being clean, they often are not. It is always safest to clean them before use.
Not just that, i mean i did use the same slide after i did previous sample, by another mean i did re-use the slide, just i only changed the coverslip, so for that re-use i did wash the slide and then wiped it with cotton cloth.
I hope i can find a source of living cells somewhere, pond i think i don't see any around and i won't take that from let's say sewers[or sewage] or streets.
Will i find living moving cells or life from my body parts or remaining? i mean i tried once with blood but i never see anything moving, the only thing moving of that blood was it is getting dry, so i don't know where i can try to find living so i can take videos or images at least, i thought with my saliva while i am still sick i can see things moving, or even from my nose, but i don't know what made those cells dead once i put them between slides and coverslips without even staining them or clean anything previously, that is why i wash the slide as i don't like to waste and throw slide after slide trying to find moving living once, but i won't give up, i once saw that moving living interesting only from a dirty juice left for days maybe a week.
