title: Cryptosporidium parvum infections in Bergen, Norway, during an extensive outbreak of waterborne giardiasis in autumn and winter 2004.
abstract: During a large waterborne giardiasis outbreak in Norway, many diarrheic patients were found to have Cryptosporidium infections. Gene sequencing identified these infections as Cryptosporidium parvum infections, although they were not identical. Whether these infections were due to a simultaneous outbreak of waterborne cryptosporidiosis or reflected background levels not normally detected is discussed.
