Popis: To describe the epidemiology of laboratory-confirmed Diarrhoeagenic Escherichia coli (DEC) cases from active facility-based surveillance in Guatemala.We collected clinical and risk factor data on enrolled patients (aged 0-52 years) with acute diarrhoea at government healthcare facilities (1 hospital and 6 clinics) in Santa Rosa, Guatemala, during 2008-2009 and 2014-2015. Stool samples were analysed, E. coli identified through culture and biochemical tests, PCR amplification of genes encoding pathotype-specific virulence factors identified specific DEC pathotypes. Healthcare-seeking adjusted incidence rates were calculated.A total of 3041 diarrhoea cases were captured by surveillance (647 hospitalisations (H), 2394 clinic visits (CV)); general E. coli prevalence was 17.9%. DEC pathotypes were identified in 19% (n = 95/497) and 21% (n = 450/2113) in diarrhoea H and CV, respectively. Enteropathogenic E. coli (EPEC) was most frequently isolated (8.2% (n = 41) in diarrhoea H, 12.0% (n = 255) in diarrhoea CV), followed by ETEC (6.8% (n = 34) in H, 6% (n = 128) in CV) and STEC (0.6% (n = 3) in H, 0.6% (n = 13) in CV). We did not find evidence of a difference in severity between DEC and non-DEC diarrhoea. Incidence of DEC clinic visits and hospitalisations was 648.0 and 29.3, respectively, per 10,000 persons aged ≤5 years and 36.8 and 0.4, respectively, per 10,000 persons aged5 years.DEC pathotypes, especially EPEC and ETEC, were detected frequently from patients presenting with diarrhoeal illness in Santa Rosa, Guatemala. Our findings suggest that preventive interventions should be prioritised for young children.
