Article and link: “Microorganisms Make a House a Home?” — https://www.the-scientist.com/?articles.view/articleNo/43840/title/Microorganisms-Make-a-House-a-Home-/
Summary: This is a brief article which overviews a study in which dust from homes were analyzed for bacterial and fungal species. The results indicate that the presence of certain fungal and bacterial species can indicate the geographical location you live and even the house’s inhabitants, from pets to people.
Connections: Using the presence of certain bacteria to ascertain information is similar to the idea of the human microbiome, as well as using the presence of certain fungi to determine geographical location.
Critical Analysis: The study found that, using the fungal data, one could predict the exact geographical location in which the home was located. Furthermore, they could predict using bacterial data whether or not there is a dog in the household — with 92% accuracy. The scientists could even predict if the house’s inhabitants were predominantly male or female, based on the presence of bacteria typically found in fecal matter (males) or the vaginal canal (females). The article itself was very brief and written for non-scientists, but it didn’t seem to have any inaccuracies. It was very interesting and insightful.
Question: What else could microbes be indicative of in everyday life?
