The fast-growing cannibalism bacteria

Scientists have found that a meat-eating bacterium can cause fatal infections that evolve rapidly, within 35 years.

Deadly is also known as "meat rotting".

The Streptococcus group A bacteria seem to attack humans since the 1980s. In the past, scientists could not determine why they developed so quickly.

Despite decades of research, the plague caused by A Streptococcus bacteria remains a major threat to human health. This fact is partly because, researchers cannot find the nature and timetable of key molecular events, turning some microbes into toxic pathogens.

However, recently, American scientists have for the first time lifted the mystery of the mysterious processes that lead to the rise of human cannibalism.

Specialist James Musser from the Institute of Clinical Society Research Institute (Texas, USA) and colleagues focused on a particularly dangerous form of meat rot infection. They attached studies of animal microbial toxicity to the gene analysis of 3,615 strains of Streptococcus with serotype M1 and trace the pathogen origin to a single head cell.

The first cell, the first cell to produce a toxin factor, evolved through a series of stages until the early 1980s, when it had genes responsible for producing two potentially toxic toxins. destruction of meat rot. According to the team, the acquisition of these genes is the last major event in the emergence of pathogens and the transformation into global disease.

Experts conclude: "Epidemic diseases caused by bacterial infections are a major threat to the health of humans and animals. We have clarified the vague decades of timetable. as well as the sequence of genetic changes that underlie global epidemics.

The analysis of this dangerous carnivorous bacterium is essential to the development of better strategies for predicting as well as controlling the emergence, emergence of strains, and effective treatments. to protect public health and vaccine preparation ".
