Little monsters under your desk
Yes, it’s true. You are not alone in your office. Even if you are not at work, there’s someone (or something) living right under your desk, in your office’s restroom, or inside of your keyboard. How is that? Researches from the University of Oregon in Eugene (USA) examined 155 rooms of a University building – offices, classrooms and toilets. According to a paper, published in the “PLOS One” magazine, they identified about 30,000 different species of bacteria. A few of them could be found in each of the rooms, some only lived in certain spaces.
The researches identified basically Proteobacteria and Firmicutes cultures. Those are common to be found inside of buildings and close to humans, plants or in the soil. They also lived in the restrooms, alongside bacteria strains that live on skin or inside humans, such as gut bacteria (for example Lactobacillus or E. coli). No big surprises here.
What does that mean for the office people? After all, it’s us who work and live with tens of thousands of those species every day. It does not mean a lot yet. Research has to go on now to estimate if the bacteria do have a bad, good or at least any influence on the human wellbeeing. But the examinations already showed that design and facilities of different rooms do have an influence on the bacteria found in the rooms. If the room was air conditioned it was mainly filled with strains that are heat- or drought-resistant. Rooms with a regular ‘natural’ ventilation were crowded with bacteria that usually lives outside of buildings.
