An unknown type of bacteria found in Irish soils has been shown to be effective against the four major antibiotics-resistant superbiotics.
Antibiotics-resistant antibiotics could kill up to 1.3 million people in Europe by 2050, according to recent surveys, and for the World Health Organization "one of the biggest threats to global health, food safety and current development ".
The new type of bacteria – called Streptomyces sp. worldview – was discovered by a team based at the Medical School of Swansea University, comprised of researchers from Wales, Brazil, Iraq and Northern Ireland. The work has been published in the boundaries of microbiology.
The soil they analyzed originated in the area of Fermanagh, Northern Ireland, which is known as the boho highlands. It is an area of alkaline pastures and it is said that the soil It has medicinal properties.
Requests for the replacement of antibiotics to combat multiple resistance have led researchers to explore new sources, including popular drugs: a field of studies known as ethnopharmacology. They also focus on environments where you can find famous antibiotics manufacturers such as Streptomyces.
A member of the research team, Gerry Quinn, a former Boho resident in Fermanagh county, knew many years of healing traditions in the area.
Traditionally, a small amount of land was included cotton cloth and was used to treat many diseases, such as toothache, throat and neck infections. Interestingly, this area was previously occupied by the Druids, about 1,500 years ago, and the Neolithic 4,000 years ago.
The main findings of the study were that the recently identified strain of Streptomyces inhibited the growth of four of the six largest multiresistant pathogens identified by the WHO as being responsible for infections related to medical care: resistant to vancomycin Enterococcus faecium (VRE), Vancomycin-resistant Staphylococcus aureus MRSA), Klebsiella pneumonia and carbinapenem-resistant Acinetobacter baumanii
It also inhibits gram-positive and gram-negative bacteria, which differ in the structure of their cell wall; General Gram-negative bacteria are more resistant to antibiotics.
It is not yet clear which component of the new species prevents the growth of the pathogens, but the team is already investigating this.
Professor Paul Dyson of the University of Medicine at the University of Swansea said: "This new type of bacteria is effective against 4 of the 6 major pathogens that are resistant to antibiotics, including MRSA. this is an important step forward in combating antibiotic resistance. "
"Our results show that it is worth exploring folklore and traditional drugs in the search for new antibiotics Scientists, historians and archeologists may have something to contribute to this task, it seems that part of the answer to this very modern problem it could be in wisdom of the past ".
