Dangerous strains of E. coli may linger longer in water than benign counterparts, study finds

A toxin dangerous to humans may help E. coli fend off aquatic predators, enabling strains of E. coli that produce the toxin to survive longer in lake water than benign counterparts, a new study finds. The research may help explain why water quality tests don't always accurately capture health risks for swimmers.
