Do different species organize themselves differently? Do some secrete poison to clear away other species? I know nothing.

If you want to make permanent slides, you might be able to obtain the materials locally. There is a topical antiseptic popular with the Spanish speaking population called Gentian Violet, available in 1% and 2% solutions. The brand I see online is mostly De La Cruz. Gentian Violet is a mixture of two or more types of Methyl Violet, with maybe some Crystal Violet thrown in as well. I have had good luck with Methyl Violet, and posted a few images of bacterial slides made with it. I suspect the antiseptic Gentian Violet should work as well, especially if you can find the 2% solution, which I think I remember seeing on Ebay.MicroBob wrote:You might make a slide from fixated and stained bacteria and show it at high magnification. The light microscope won't show more than the shape though.
I once had a look at slides from human bacterial diseases and can remember that the different bacteria arranged themselved in very different ways.
