Salmonella

Genetically-Modified Salmonella destroys Brain Tumors

Scientists developed a strain of Salmonella that fights aggressive brain cancers which produced a remarkable 20% rate of tumor remission in a rat model, where there are normally no survivors. The bacteria were genetically equipped with a sophisticated tumor-homing mechanism along with cancer fighting weapons, causing the tumors to effectively self-destruct.

Evolution in Action

Scientists from Harvard Medical School and Technion-Israel Institute of Technology have ingeniously visualized the Escherichia coli evolution through ever increasing amounts of antibiotics. Inspired by a Hollywood movie billboard, the team constructed the so called Microbial Evolution and Growth Arena i.e. MEGA plate to be able to monitor bacteria’s movement, survival and resistance.

New Synthesis Technique Leads to Over 300 Candidate Antibiotics

The combination of drug misuse, reductions in antimicrobial research by the pharmaceutical industry, and the rapid evolution capabilities of microorganisms has resulted in pathogenic bacteria with stronger and stronger drug resistance. This is an issue that some fear if not handled correctly, could lead to the evolution of a “superbug” that is resistant to everything in our arsenal.
