    How Bacteria Hinder Chemotherapy

    To the list of reasons that chemotherapy sometimes does not work, we can now add one more: bacteria. In a study just published in Science, researchers describe their findings showing that certain bacteria can be found inside human pancreatic tumors. The findings further revealed that some of these bacteria contain an enzyme that inactivates a common drug used to treat various cancers, including pancreatic cancer. Working with mouse models of cancer, the scientists demonstrated how treatment with antibiotics on top of chemotherapy may be significantly superior to treatment with chemotherapy alone.

    Bacteria Alert by Scientist

    The Israeli crystallographer, who shared the chemistry Nobel with Venkatraman Ramakrishnan and Thomas A. Steitz in 2009 for her work on ribosome, was delivering the 79th Foundation Day lecture on “Next Generation Environmental Friendly Antibiotics” at Bose Institute on Thursday. “Resistance to antibiotics is a real big problem to modern medicine. Multi-drug resistance has developed not because we use antibiotics, but because bacteria has evolved and uses mechanisms against other bacteria in their fight for resources,” Yonath said.
