Japan finds link between gut bacterium and COVID deaths

Japanese scientists from Nagoya University have established a link between the presence of an intestinal bacterium from the Collinsella genus in the human body and low mortality when infected with coronavirus, the results of the study are posted on the website of The Japan Times newspaper.

The researchers concluded that Collinsella is able to convert bile acids into ursodeoxycholic acid, which prevents COVID from binding to the receptors of the cells of an infected person. 

According to experts, the presence of a large number of these bacteria in the intestine should suppress the activity of the virus, provide mild symptoms of infection and, as a result, a low probability of death.

To confirm their hypothesis, university staff examined 953 people from countries with different levels of mortality from coronavirus infection. As a result, in Japan, the Republic of Korea and Finland, where the mortality rate is considered low, a large concentration of intestinal bacteria was found in 34-61% of study participants. While residents of Belgium, the UK, Italy and the USA, where there is a high mortality, a large concentration was detected only in 4-18% of cases.

The corresponding study explains the different incidence of new coronavirus, the severity of the disease and mortality in different countries.

Meanwhile, American scientists have managed to isolate two previously unknown antibodies that can neutralize the omicron strain of coronavirus.
