Scientists Discover New Antibiotics Family in Soil

Researchers from The Rockefeller University have discovered a new class of antibiotics in soil that is capable of killing off several antibiotic-resistant pathogens. The research was published in the Nature Microbiology journal on February 12, 2018. The new antibiotic is called Malacidins. The team analyzed more than 1000 unique soil samples to better understand how these peptide compounds are produced and how to exploit them for fighting bacteria. They had used DNA information that encodes production of antibiotic in daptomycin to study it. This discovery could be a useful weapon in field of medicines.

Key Highlights:-
1. The bacteria attacked with the malacidins did not develop resistance.
2. Malacidins,was successful in sterilizing methicillin-resistant Staphylococcus aureus, also known as the superbug MRSA.
3. Malacidin class is not a universal cure against all bacteria. The targeting mode is only effective against gram-positive bacteria, species with a very thick cell wall.
4. This antibiotic treatment would not be effective against gram-negative bacteria such as pneumonia and UTIs.
