We intend to know, with the help of citizens, different microorganisms such as bacteria, mites or fungi with which we live in our surroundings.

To participate, just follow the following instructions:

Collecting samples: for this you need a cotton swab and a transparent sachet with zip closure.

Follow the next procedure: slide down the edge of the swab over the top of a door of any room in the house (room, living room, bathroom …) making sure there is dust or lint in that place. A small sample of that powder or lint will be inserted along with the swab in the plastic bag and shipped.

In addition of the samples of dust we also collect other samples such as a small fragment of the material (5×5 cm) of a pillow, of a old teddy bears or used clothes. Also little soil samples of planted pots.
