Bacteria begin to win. Antibiotic resistance is a global problem , photo:
His name is teixobactin
and is the most promising of a group of 25 new antibiotics. Tests on animals have shown that it kills bacteria but is harmless to mammalian tissues.
– It fights bacteria such as methicillin-resistant Staphylococcus aureus (MRSA) and Mycobacterium tuberculosis – provides weekly “Nature” lead author of the study, Kim Lewis of Northeastern University in Boston. He adds that the novel antibiotic obtained from cultures of bacteria is not in the lab, but in their natural environment – in the soil.
Teixobactin does not work for all bacteria, only those so-called gram-positive bacteria. For this – as provide researchers – sensitive bacteria can not develop antibiotic resistance and the resistance is a major threat today, for example in the treatment of tuberculosis.
Now teixobactin must be tested on humans. Doctors have high hopes, because it would be the first effective antibiotic in 1987.
