Japanese scientists from Nagoya University have established a link between the presence of an intestinal bacterium of the genus Collinsella in the human body and low mortality in the event of infection with coronavirus, study results are published on The Japan Times newspaper website.
The researchers concluded that Collinsella is able to convert bile acids into ursodeoxycholic acid, which prevents COVID from binding to receptors on cells of an infected person. intestine is expected to suppress virus activity, cause mild symptoms of infection and, therefore, a low probability of death.
< p>To confirm their hypothesis, university staff examined 953 people of countries with different levels of coronavirus infection mortality. Accordingly, in Japan, the Republic of Korea and Finland, where the mortality rate is considered low, a high concentration of intestinal bacteria was found in 34-61% of study participants. While residents of Belgium, the United Kingdom, Italy and the United States, where mortality is high, a high concentration was only detected in 4-18% of cases.
The corresponding study explains the different incidence of new coronaviruses, disease severity and mortality in different countries.
Meanwhile, American scientists have succeeded to isolate two previously unknown antibodies that can neutralize the omicron strain of coronavirus.
