A new study on humans’ microbial auras and what they can do was published on Tuesday in the journal PeerJ. The research confirms the findings claiming that not all microbes are harmful and suggests that some bacteria cannot be washed away, no matter how much we’d strive to get rid of them.
There has always been a silent war between humans and bacteria in their homes. We use sanitizing products promising highest levels of efficiency against microbes, while many more studies suggest we’d be better off surrendering to them.
This belief has been confirmed once again by this Tuesday’s scientific paper in the journal of PeerJ. The study, conducted by researchers at the University of Oregon, has proven that humans have unique microbiomes that surround them at all times, regardless of the efforts they make to shed skin germs.
11 participants have agreed to take part in the experiment. They were placed in a room that has been thoroughly sanitized prior to the experiment. 312 samples have been collected from the spaces and objects that the respondents have used. Their microbial sequencing has been compared to the bacteria in a similarly hygienic room that was left unpopulated all throughout the experiment.
Comparisons have indicated that there were millions of unique microbial patterns in the inhabited room. These ‘clouds’ differed from one individual to another, according to scientists. There were 14 million sequences of thousands of bacteria, which have helped researchers precisely identify each respondent in the room.
Investigators have further explained that these unique bacteria patterns surround people at all times and they make new combinations every time people interact with each other. This new find may be used by medical experts to understand how certain diseases are orally transmitted among individuals.
The most frequent bacteria identified in humans’ microbial clouds were mouth Streptococcus, skin-based Corynebacterium and Propionibacterium microbes. Yet, the combination between them is unique, a new combination of bacteria corresponding to every respondent in the study group.
James F. Meadow, the lead author of the experiment, has concluded that bacteria are invincible and sometimes useful to people. Certain bacteria are good for our immune system, so they should not be excessively removed from the surface of the skin.
The unique microbial clouds can help forensic investigators identify criminals whenever finger prints are not available. Meadow believes there are many benefits that the new finding brings to the science community; therefore, research in this domain should be further encouraged.
