The Source of the Germs

This shows a close-up of a worn and dirty baseball cap. The sweatband is stained with sweat and grime, making it a breeding ground for bacteria. A cotton swab is shown collecting a sample from the soiled fabric.

Culturing the Bacteria

After swabbing the dirty cap, the sample was transferred to a petri dish containing a nutrient-rich agar gel. This image shows the result after incubation: a large, fuzzy, yellowish bacterial colony has grown, demonstrating the presence of significant microbial life on the cap's surface.

A Microscopic View

Finally, a sample of the bacterial colony from the petri dish was examined under a high-powered microscope. This image reveals the individual bacteria, which are rod-shaped (bacilli) and have been stained purple for visibility. These are the millions of individual organisms that make up the colony seen in the previous image, all originating from the dirty sport cap.
