Within the Norwegian surveillance architecture, E. coli enteritis functions as a classification boundary aggregating all notifiable diarrheagenic E. coli lineages identified through standardized laboratory notification channels [1][2]. The EHEC/STEC segment is delineated by the presence of stx1 and stx2 gene variants and their subtypes, distinguishing it from commensal intestinal flora [1]. Conversely, the non-EHEC segment explicitly captures enteroinvasive E. coli, typical and atypical enteropathogenic E. coli, enterotoxigenic E. coli, and enteroaggregative E. coli, maintaining clear administrative separation from the toxin-mediated pathway [2]. Pathotype differentiation relies on specific virulence markers, although certain molecular assays cannot fully resolve overlaps between enteroinvasive E. coli and Shigella species [2].
Disease overview
BacterialEscherichia coli enteritis, all reported pathotypes
大肠埃希菌肠炎（所有报告型别）
Escherichia coli enteritis represents a classified surveillance aggregate in Norway encompassing multiple diarrheagenic pathotypes, primarily divided into the enterohaemorrhagic/shiga-toxin-producing E. coli (EHEC/STEC) component and distinct non-EHEC variants [1][2]. The EHEC/STEC fraction carries shiga-toxin genes capable of producing a clinical spectrum ranging from asymptomatic carriage to severe haemorrhagic colitis and haemolytic uraemic syndrome [1]. Concurrently, the non-EHEC category comprises enteroinvasive, enteropathogenic, enterotoxigenic, and enteroaggregative strains managed under a related but separate reporting framework [2]. Reported case volumes over recent decades predominantly reflect broadened primary-laboratory screening protocols rather than genuine epidemiological surges [1][2].
