An entirely new super-toxic bug is causing the frightening food poisoning outbreak that has sickened at least 1,600 people and killed 18, researchers and global health officials said Thursday.
The DNA of the new E. coli strain, believed to have contaminated salad vegetables, was analyzed by Chinese and German scientists. It contains several genes that cause antibiotic resistance and is similar to a strain that causes serious diarrhea and is found in the Central African Republic, according to a statement from the Shenzhen, China-based laboratory, BGI. Those scientists were working together with the University Medical Center Hamburg-Eppendorf.
