As per a new study published in the Journal of Royal Society Open Science, scientists learned that only 3.5% of the bacteria species present in the chimpanzee’s nest came from its own saliva, skin or faces. The study was conducted by studying on the abandoned chimpanzee nests in Tanzania’s Issa Valley. In contrast to that the human beds as per earlier studies in North Carolina was found to have more number of bacteria species specifically thirty-five percent.
Parasites like ticks and fleas were also scarcely present in the chimpanzee beds.
Megan Thoemmes—a PhD student at North Carolina State University said that we need to redefine of what we think of clean within the environment.

There are certain things that needs to be kept in mind before you start getting boggled on this new finding.
For beginners, chimpanzees make a new nest on a per night basis and they also bear pains to bend over the side of their nests when defecating. So, this explains that why there is a lower concentration of body-related bacteria in a chimpanzee nest than the bedsheets of human beings who spend a third of their lives in.
It is important to mention that even the scientists were amazed by these findings.
Thoemmes said that they expected to see a lot of ectoparasites and a lot of faecal bacterium, as there had been many evidences indicating that faecal bacteria builds up in the skin of chimpanzee.
Jonathan Eisen—an evolutionary microbiologist at the University of California said that it is noteworthy that the research only looked at the kinds of bacteria present, not on the overall quantity of microbes. He said that it depends on how one defines “dirtier” which for him means more stuff.
He further added that sitting in one’s own microbes is not the issue for health, rather it is getting exposed to someone else’s microbes is what is the real issue.
Eisen said, so health-wise the dirtiest part is sleeping in beds that lots of other have slept in.
There has been no earlier study done in which a humanly built environment—beds were compared with that built by a wild animal—chimpanzee nests.
Though the new research does not provide ample data, however, Eisen declared the work done to be “incredibly novel”.
