However the gut microbiomes of most astronauts have become more diverse in space, rather than the other way around, despite limited exposure to new bacteria. And more variety is generally healthier. “Typically, people with inflammatory bowel disease can see a decrease in microbiome diversity. An increase in diversity usually indicates greater disease resistance,” explains Lorenzi. The researchers suggest that this may be due to the large selection of products available at the station. More than food and drink options are available to astronauts, according to NASA, which is more than what people normally eat on Earth. in the gastrointestinal tract, the internal microbiome of the astronauts suffered losses.
In addition to the increased diversity
Two types of bacteria – Akkermansia and Ruminococcus Hungary Phone Number List which maintain the integrity of the lining of the digestive tract and play an important role in the breakdown of carbohydrates – decreased by five times. Negative changes also occurred with the skin microcover of the astronauts. The subjects had a decrease in the number of various skin microorganisms, including gammaproteobacteria, which are part of the healthy skin microbiome. According to scientists, hypersensitivity in space. Fortunately, most of the indicators returned to normal after the return of the astronauts to Earth. The influence of space on the human microbiome is also studied by Russian scientists. Researchers at Samara State.
Changes in the gut microbiome can affect
University have studied how space flight has affected BT Lists the bioprofiles of enterobacteria and staphylococci, typical representatives of the human internal microflora. The experiment showed that all bacteria survived better in orbital flight than on Earth. In addition, their biological, including pathogenic, properties changed. food metabolism, bone health and even cognitive performance, scientists say. Longer stays in space, such as months to Mars and back, are likely to exacerbate these problems. The saying “You are what you eat” is especially relevant here Grace Douglas of NASA.
