a pigment sample of “staphylococcus aureus:”
a bacterium on skin and in nasal passages that causes pimples, cellulitis and MRSA

found on the skin of 30% of people, naturally, and doesn’t cause any disease because it can be part of your natural epidermal bacterial flora.

Vibrio cholerae growth on calcofluor agar at day five. (37*C/ 25*C/ 37*C)

This is really cool. In this indicator assay, the calcofluor glows under UV light with the presence of cellulose binding. The brighter it glows, the greater the presence of cellulose. Vibrio bacteria biofilms are comprised mainly of cellulose. Its interesting, however, that the biofilm is only formed in a ring, almost as a protective barrier. I’m not sure what this means, because other vibrio don’t form cellulose like this. But the image itself is impressive.
