Scientists have developed 100 new types of antibiotics on the basis of a substance present in frog skin
Scientists have known for a long time that frog skin contains a number of powerful chemical substances, which are able to kill pathogenic bacteria, viruses and fungi. However, these substances are also poisonous for people, so it was impossible to use them in medicine.
But now Arab specialists have managed to modify chemical substances in such a way that they are deprived of their harmful effects. Correction of molecular structure of these chemical substances made the less toxic for people, but even more harmful for pathogens. Scientists also assured that these chemical substances remained resistant to the action of destroying enzymes, attacks of which they are subjected to when coming into blood. As a result, new antibiotics stay longer in human blood system and are more effective fighting infections.
As yet, the researches have studied skin discharge of more than 6 thousand species of frogs, which enabled them to identify a hundred of now "frog" antibiotics. One of such antibiotics, excreted form secretion of endangered frog Rana boylii, may kill methicillin-resistant Staphylococcus aureus (MRSA). These bacteria belong to most spread hospital-acquired infections. The symptoms of the disease vary from rash to pneumonia, abscess and sepsis. Most frequently MRSA affects people who are immunocompromised.
