Researchers at CalTech , The Washington University School of Medicine, and the University of Florida have successfully modeled the ‘Type Four Secretion’ system unique to legionella bacteria. Previously, other scientists have not been able to accurately model this mechanism as the bacteria are only about 40 nanometers in diameter. This process, referred to as the ‘Toxin Gun’ by some, is responsible for the bacteria’s noted resistance to some antibiotics. The ‘Toxin Gun’ secretes thousands of toxic molecules that infect and significantly weaken cells, overloading the body’s immune response. The ‘Toxin Gun’ also shoots out material that is coded with antibiotic resistance genes, thereby allowing more…
