According to a new study, germs in dust collected from your home, can tell about the location of your home in relation to geography together with proportion of male and female members that are living in the house. It can also tell that if there is a pet at the home.
The new findings reveal about striking amount of microbial diversity at your home.
According to co-author of the study Noah Fierer, associate professor at the University of Colorado Boulder in the US, "Every day, we are surrounded by a vast array of organisms in our homes, most of which we cannot see. We live in a microbial zoo, and this study was an attempt to catalog that diversity".
Approximately 1,200 homes across the US were analyzed in the study. Each home consists of over 5,000 different species of bacteria and nearly 2,000 species of fungi on average.
Study coauthor Noah Fierer, a biologist at the University of Colorado, said that it is known since long that microbes are present in homes. Fierer added that distinct bacteria were found in homes, where only women were living and homes having only male members. Fierer said that geography can tell about fungi in a home. In case of bacteria, geographical location of the home matters less than whom one is living with.
