They find effective bacteria against 4 multi-resistant pathogens



MadridIt has been proven that an unknown strain of bacteria found in Irish soils is effective against four of the six major antibiotic-resistant superbooks.

According to the latest research, antibiotic-resistant superbooks in Europe could kill up to 1.3 million people by 2050, and for the World Health Organization they represent "one of the most serious threats to global health, food security and development." current ".

A new strain of bacteria – which was named Streptomyces sp. myrophorea– was discovered by a team from Swansea University Medical School, consisting of researchers from Wales, Brazil, Iraq and Northern Ireland. Work published in Frontiers in Microbiology,

The soil they analyzed originated in Fermana, Northern Ireland, which is known as the Boho Highlands. This is an area of ​​alkaline pastures, and they say that the soil has healing properties.

The search for replacement antibiotics to combat multiple resistance has prompted researchers to explore new sources, including popular medicines: a field of study known as ethnopharmacology. They are also focused on an environment where you can find well-known manufacturers of antibiotics, such as Streptomyces,

Soil to which medicinal properties belong

One member of the research team, Jerry Quinn, a former Boho resident in Fermana County, has known about the healing traditions of the region for many years.

Traditionally, a small amount of dirt was wrapped in cotton fabric and used to treat many diseases, such as toothache, throat and neck infections. Interestingly, this area was previously occupied by druids about 1,500 years ago and Neolithic 4,000 years ago.

The main findings of the study were that the voltage Streptomyces recently identified inhibited the growth of four of the six major multi-resistant pathogens identified by WHO as responsible for medical-related infections: Enterococcus faecium resistant to vancomycin (VRE), Staphylococcus aureus Resistant to vancomycin (MRSA), Klebsiella pneumonia and resistant to Acinetobacter baumanii carbenepenemIt also inhibits gram-positive and gram-negative bacteria, which differ in the structure of their cell wall; As a rule, gram-negative bacteria are more resistant to antibiotics.

It is not clear which component of the new strain prevents the growth of pathogenic microorganisms, but the team is already studying this.

Professor Paul Dyson from Swansea University School of Medicine said: "This new bacterial strain is effective against 4 of 6 major antibiotic resistant pathogens, including MRSA." Our discovery is an important step forward in the fight against antibiotic resistance.

“Our results show that it is worth looking for folklore and traditional medicines in search of new antibiotics.

Scientists, historians and archaeologists can contribute to this task. It seems that part of the answer to this very modern problem may be in the wisdom of the past. "
