Experts at mit have developed a new kind of antibiotic, which is based on the venom of South American wasps Polybia paulista. A substance capable of killing bacteria and do not damage human cells.
Scientists have conducted a series of successful tests with mice. The most powerful peptide was able to cope with the Pseudomonas aeruginosa bacteria have developed resistance to most antibiotics. The peptide was able to disrupt the cell membrane of bacteria.
Now scientists are busy creating modifications to peptide, to get the perfect version of the substance in the most low dose.
Peptides are molecules consisting of two or more amino acids connected by peptide bonds, they are involved in cell division and regulate their work. Through its immune protection to many organisms, including human, produce peptidesthat can kill bacteria. To help combat the emergence of antibiotic-resistant bacteria, many scientists are trying to adapt these peptides as potential new drugs.
