E coli outbreak: WHO says bacterium is a new strain

World Health Organisation says fatal E coli is a mutant blend of two different varieties and has never been seen before

Excerpt:

Preliminary genetic sequencing suggests the strain is a mutant form of two different E coli bacteria, with lethal genes that could explain why the Europe-wide outbreak appeared to be so big and dangerous, the agency said.

Hilde Kruse, a food safety expert at the WHO, told the Associated Press that "this is a unique strain that has never been isolated from patients before".

She added that the new strain has "various characteristics that make it more virulent and toxin-producing".
