In the blood of alligators and crocodiles proteins were discovered with high antibacterial and antifungal activity.
Unlike men, alligators can combat fungi, viruses and bacteria without the body being previously subjected to these micro-organisms. The researchers have demonstrated the McNeese State University and Louisiana state university who collected the blood from alligators and analyzed the white blood cells, which are the cells appointed to immune defense.
According to the results of the study, presented to Congress by the American Chemical Society in New Orleans Corsican (USA), from these cells can be extracted a protein that has a high antibacterial activity. It is possible that this feature is due to an adjustment mechanism that leads to faster healing of injuries, since the alligators are frequently injured during the struggle for the conquest of territory.
The protein extract was tested on different types of bacteria, including microbes particularly resistant to antibiotics already in use as methicillin-resistant Staphylococcus aureus, very widespread. The results are promising, given the good activities on six of the eight strains of Candida albicans which has been tested. The next step will be to identify the chemical structures of proteins and identify which are the most effective. According to the researchers, the white blood cells of alligators could contain at least four promising substances and, once understood, we can begin to think of the new antibiotic drugs. - coolstuff
