The CRS was defined as positive when culture was positive or, in the case of a negative culture (or if conventional culture was not performed or unable to detect the pathogen [i.e., EHEC, EPEC, EAEC, ETEC, C. difficile]), when the result was concordant with the one previously obtained with the BD Max extended enteric bacterial panel. When a discrepancy was noticed, CRS was defined as positive when at least one independent PCR assay used for confirmation was concordant with Novodiag Bacterial GE+.
