Scientific discoveries: Irish soil and grasslands are an antidote to four super-immune to antibiotics



"Our results show that it's good to investigate folklore and drugs traditional in searching new antibiotics"Said Professor Paul Dyson from the Faculty of Medicine at the University of Swansea, Wales, England. This phrase represents the whole changes in the focus of science who searches for ancestors some answers to present-day problems.

There he is unknown bacterial strains found on Irish soil proved effective against four of the six major superbugs that are resistant to antibiotics.

According to recent research, antibiotic-resistant superbugs can kill up to 1.3 million people in Europe by 2050. For the World Health Organization, this is "one of the biggest threats to global health, food security and current development".

New strain of bacteria, named Streptomyces sp. Myrophorea was discovered by a research team from Wales, Brazil, Iraq and Northern Ireland. The work was published at Border in Microbiology.

Ethnopharmacological promise

The land they analyzed came from an area Fermanagh, Northern Ireland, known as the "Boho Plateau". This is an "alkaline" grassland area and is always said to have healing properties.

The search for new antibiotics to combat various resistance prompted researchers to explore new sources, including popular medicines: field of study known as ethnopharmacology. They also focus on an environment where you can find manufacturers of antibiotics known as Streptomyces.

The country with healing properties

One member of the research team, Gerry Quinn, a former resident of Boho, in the city of Fermanagh, had 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 toothache, throat and neck infections. Interestingly, this area was previously occupied by Druids, around 1500 years ago, and the Neolithic 4,000 years ago.

"The main findings of this study are the newly identified Streptomyces strains inhibiting growth four of the six major multiresistant pathogens identified by WHO as responsible for infections associated with medical care: Enterococcus faecium (VRE) that is resistant to vancomycin, Vanaphycococus aureus that is resistant to vancomycin (MRSA), Klebsiella pneumonia and Acinetobacter baistanii that are resistant to carbenepenem, "the experts said.

The mystery that must be solved

Nonetheless which component is unclear The new strain prevents the growth of pathogens, but the team has investigated this.

Dyson concluded: "Our discovery is an important step forward in the struggle against resistance to antibiotics. You must investigate traditional medicines. that scientist, that historian and archaeologist They 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. "
