A study has revealed that we live around an alarming amount of fungi and bacteria species. The study of what kind of fungi and bacteria species we see in our homes and where they come from is new science, but the fact is that these species are living with us in our homes.

According to authors of the study, there is no way to deal with these microbes. If someone wants to change the types of microbes living in their homes, then the best method is to shift to a different house, they said.

The study researchers are trying to find out the ratio of men and women in the house by looking at composition of dust in the house. The study has been published in Proceedings of the Royal Society B this week.

Noah Fierer, a microbial ecologist at the University of Colorado at Boulder and an author of the study, and other researchers said that the communities of the microbes can tell several things about the people they are living with. Fierer said, "For bacteria, it appears to be the human and non-human animals (i. e. dogs and cats) that you live with. We live in a microbial zoo, and this study was an attempt to catalog that diversity".

According to Fierer, most fungi come from outside through windows, ventilation and clothing. After analyzing the dust from more than one thousand homes, the researchers found that every home can have more than 5,000 species of bacteria and about 2,000 fungi species.
