Monitoring Water Sources for Environmental Reservoirs of ToxigenicVibrio choleraeO1, Haiti

The cause of the severity of disease in this stx 2f STEC case and the source of the infection could not be determined.The parrot in the hotel in Turkey could have been the source if birds are a reservoir of stx 2f STEC.Conversely, the uncooked beef and barbecue cannot be ruled out, because O8:H19 has been found in cattle, pigs, and sheep (7).This case shows that STEC subgroups known to cause relatively mild disease can occasionally cause severe disease and that surveillance based upon a small group of serotypes underestimates the number of severe STEC infections and increases the chance of missing emerging serotypes.
