Une super-bactérie très virulente

The presence of a sugar additive promotes the appearance of a very virulent super-bacteria

Advances in analytical chemistry have enabled scientists to reveal certain harmful substances to human health. Until recently, researchers discovered that a sugar additive present in certain foods may have contributed to overgrowth of an extremely harmful bacteria in the USA. Thanks to the study carried out in 2018, the accusing finger is pointed towards trehalose, found in chewing gum and nutrition bars.

If these conclusions are corroborated, they will constitute a strong alert on the possibility that certain additives, a priori without danger, are the cause of health problems. And this, as soon as they have been inserted into our food. In this case, the presence of trehalose has been associated with the multiplication of two varieties of Clostridium difficile bacillus.

In recent years, this microbe antibiotic resistant quickly gained ground. It has become a real challenge for the medical world and its appearance coincides with the discovery of trehalose.

Sugar is the cause

Trehalose was accepted as an additive for several foods in 2000 in the USA. Three years later, several cases of epidemics involving Clostridium difficile strains have been reported. Although other elements may also come into play, scientists have estimated that trehalose is the main trigger.

RT078 and RT027 are the C. difficile strains of concern. After analyzing the genome of each of them, the scientists found DNA sequences. These allow the lines easily absorb small doses of trehalose.

To confirm their results, they carried out a experiment on mice exposed to line RT027. At the end of the experiment, they found that the death rate was much higher in mice given small injections of trehalose. The cause was not the increase in the number of bacteria, but the fact that the sugar promoted the multiplication of toxins.

Unfortunate consequences for health

In 2011, the statistics of Centers for Disease Control and Prevention in the United States have shown that the C. difficile was the cause about 500,000 cases of infection during the year. This bacteria also caused 29,000 deaths during the first 30 days after diagnosis.

“These strains have existed in humans for several years without causing serious disease outbreaks. During the 1980s, they did not present any epidemic or hypervirulent character, but from 2000, they became predominant and caused serious epidemics. “

James Collins, researcher at Baylor College of Medicine.

He went on to say this : “The important conclusion of our study lies in an awareness of the unintended consequences that this sugar, once considered safe for human health, can have. “
