Results: After finding that a forgotten plaque, which was initially filled with Staphylococcus, had been contaminated by a fungus, Flemming noticed that the areas surrounding the fungus were free of Staphylococcus. His results were that the bacteria was destroyed by the fungus, which was identified as a <em>Penicillium</em>. He said that (quote)<em> "...at a considerable distance around the fungus, the growth of Staphylococcus colonies were suffering lysis ..." </em>
His observations were qualitative, as he could just observe and describe what he was happening, but he did not perform any count quantities. In his descriptions, he said (quote) "...<em>What had previously been a well-formed colony, it was now a faint shadow of its former form...". </em>He described the situation as a previously well-formed colony, to a shadow of its former form. He characterized the colony but did not count the surviving or dead cells.
