Abstract

In March 2010, a massive outbreak of gastroenteritis started in the region of Antofagasta (northern Chile). The outbreak was mainly attributed to Norovirus genogroup II although ETEC strains were also isolated with high frequency from clinical samples. We review this outbreak and determined that ETEC was an underestimated etiologic agent.

Keywords: Co-infection ETEC - norovirus; Colonization factors; ETEC; Enterotoxigenic E. coli; Massive outbreak; Toxigenic profile.
