Question: What is it the things you work with that glows because it looks like glowing worms.

Haha, they do look like glowing worms, you’re right!

They are fluorescently stained Candida (the fungus I work with). They are magnified about 400 times, so you can imaging how small they are.

To get this image, I grew the biofilms on plastic discs, then added two stains – a green stain that only stains Candida, and a red one that only stains bacteria. This way I can see what kind of shape the Candida are (and this is important because if they are circular, they are considered non-pathogenic, or non-harmful, but if they are stretched, they are more pathogenic!).
