Researchers are beginning to understand the importance of the cervical spine in mammals and the different ways in which organisms can mimic these fungal communities, which is important in the management of fungal infections. natural response.

In a further study on npj Biofilms and Microbiomeresearchers from the University of Minnesota and the Czech Academy of Sciences reported a model of the establishment of gut fungal communities and fungal-bacterial relationships in various nonhuman primates (captives and wild animals), and populations with a variety of food security practices (traditional agriculturalists, herdsmen and western populations).

The research team was led by science professor Ashok Kumar Sharma, a former postdoctoral researcher with the U of M, now with Cedars-Sinai. The scientists separated the ITS2 and 16S rRNA gene markers from fecal samples of four nonhuman primate species and three different human groups to show the formation of the fungal and bacterial community.

“Understanding how the fungal community changes and interacts with bacterial communities in response to different conditions such as food and lifestyle provides a basic reason to explore and their role in human health and diseases, ”Sharma said.

Similarities between captive apes and post -industrial humans suggest the impact of food and lifestyle factors on genetics in the formation of the fungal community. gut and fungal-bacterial relationships. The high similarities in composition among those who eat non-industrialized foods and wild apes further support these findings.

Overall, the results demonstrate the influence of ecological, behavioral and environmental factors on the functioning of the primate stomach mycobiome, the communities of fungi that inhabit the stomach of primates.

The researchers found:

  • It plays an important role in ecological factors, including the food environment in the formation of the fungal community in the primate’s stomach. This is in contrast to the bacterial breakdown of the gut, which is more altered by host genetics.
  • The differences between them in primate populations not only affect the fungal communities but also how fungi and bacteria live together in the gut.
  • Fungal and bacterial taxation can be combined with the same active power to perform normal metabolic functions, such as lowering carbon levels.

“These data show that the external environment plays a very important role in populating the human community in the primate womb; if those games are not seen in the short term or the long -term colonizers .The lack of fungal diversity in the western / human industry is about health, ”said Andres Gomez, PhD, an assistant professor in the Department of Animal Science.

“Because environmental factors are more important than host genetics in the formation of the mycobiome, we can assume that the mycobiome can be a better representation of a healthy and stable living ecosystem. primates live, ”said Klara Judita Petrzelkova, PhD, a researcher at the Institute of Vertebrate Biology of the Czech Academy of Science.

In the future, measuring the supply of specific food sources to determine the activities of the fungal group in the gastrointestinal tract is an important task moving forward.
