Using advanced metagenomics techniques, researchers have found that conventional culture- based lab tests may often misdiagnose the microbial causes of diarrheal diseases in children. The study, based on samples from Ecuadorian children, also found that a common strain of the E. coli bacterium may be more virulent than previously believed.
