Dust researchers find 5,000 species of bacteria in one home
A study by the University of Colorado at Boulder may give you some inspiration to get out the dust rag. The scientists ran a study on common household dust particles from 1,200 homes across the United States, and on average they found that each home had more than 5,000 different species of bacteria and 2,000 fungal specimens. They also found that the fungal species and bacteria can also be very telling about where the home is located and who lives in the home. The fungi typically blows in from the outdoors, and scientists were able to determine what part of the country a home is located in based on what kind of fungi they find. They can also see if men, women or pets live in a home based on the bacteria. Experts say most of the microbes are harmless, and some of them are even beneficial.
