Stopping the antibiotic resistant super-bugs
Breakthrough !
Vancomycin is typically used to deal with superbugs, although there are other super-anti-biotics which break apart toxic bacteria and amoebas, and certain parasites very rapidly.
Resistance to a treatment happens when the "bug" (bacteria/amoeba/parasite) finds a way to develop a mechanism to hide from (not be affected by) an antibiotic. Some bugs developed a type of "slime coating" which is designed to keep one's own immune system from even recognizing that there is an invader in there "using STEALTH" masking.
Researchers have been able to re-engineer a successful antibiotic, vancomycin in this case, to have 3 new mechanisms which deal with "bug's" defence mechanisms. The researchers feel that the 3 modifications will offer at least two more chances for the vancomycin to stop the bug, even if the bug were to adapt (mutate) to withstand one of the 3.
Researchers tested the modified vancomycin using a "resistant to vancomycin strain of bacteria" as the bug.. In over 50 plate studies (something which is done to re-colonize any resistant bacteria on a fresh growth media plate, to see if antibiotic resistance happens), and found that the "bugs" were not able to adapt, or mutate and thereby survive.. That is very very promising that the same technique can be used with other antibiotics to build in the new modifications.
The new vancomycin was developed by a Scripps Research Institute team.

I think we could benefit by paying more attention to Scripps Research Institute - their breakthroughs and ah-ha's have been staggering, and very amazing - quite a potential to solve some major medical issues across the board, worldwide..
