Madrid. The unknown bacterial strain found on Irish soil has been shown to be effective against four of the six antibiotic-resistant bacteria.
Antibiotic superbugs can kill up to 1.3 million people in Europe by 2050, according to recent research, and for the World Health Organization, it is "one of the biggest threats to global health, food security and development." this time ".
New bacterial strains – which have been mentioned Streptomyces sp. myrophorea– Discovered by a team based at Swansea University Medical School, which consists of researchers from Wales, Brazil, Iraq and Northern Ireland. This work was published at Border in Microbiology.
The land they analyzed came from the Fermanagh area of Northern Ireland, known as the Boho Highlands. This is an alkaline grassland area and it is said that land has healing properties.
The search for replacement antibiotics to combat various resistance has led researchers to explore new sources, including popular drugs: a field of study known as ethnopharmacology. They also focus on an environment where you can find known antibiotic producers such as Streptomyces.
Land that is associated with healing properties
One member of the research team, Gerry Quinn, a former resident of Boho, in Fermanagh County, has known the tradition of healing the area for years.
Traditionally, a small amount of dirt is wrapped in cotton cloth and is used to cure many diseases, such as infections of the teeth, throat and neck. Interestingly, this area was previously occupied by Druids, about 1,500 years ago, and Neolithic ones 4,000 years ago.
The main finding of the investigation is that of strains Streptomyces recently identified inhibited the growth of four of the six major multi-resistant pathogens identified by WHO as causes of infections associated with medical care: Enterococcus faecium resistant to vancomycin (VRE), Staphylococcus aureus Resistant to vancomycin (MRSA), Klebsiella pneumonia and resistant to Acinetobacter baumanii carbenepenem. It also inhibits gram-positive and gram-negative bacteria, which differ in the structure of their cell walls; In general, gram negative bacteria are more resistant to antibiotics.
It is not clear which new strain component prevents the growth of pathogens, but the team has investigated this.
Professor Paul Dyson from the Medical Faculty of Swansea University said: "This new type of bacteria is effective against 4 of the 6 main pathogens that are resistant to antibiotics, including MRSA." Our findings are an important step forward in the fight against antibiotic resistance.
"Our results show that it's good to investigate folklore and traditional medicines in finding new antibiotics.
Scientists, historians and archaeologists may have something to contribute to this task. It seems that some of the answers to this very modern problem can be in the wisdom of the past. "
