My team are working on bacteria. We swab a bird, tire, dugout, and telephone. It work and it was very disgusting. Everything we swab has a bacteria on them. I don't know why some of them doesn't work. The tire was big, the telephone just small but at least there is something than nothing, the bird formed like a "V" and the dugout was just a regular bacteria. The ones I just discuss are bacteria. After my team and I are with it, we threw right away because it was disgusting.
