AIM: Co-infections with viral and bacterial enteropathogens often augment severity of diarrhoea, however, there is limited evidence on the clinical importance of bacterial enteric co-infections. We investigated the rate, type and impact of bacterial enteropathogens and their associations in children with gastroenteritis.
METHODS: Retrospective cohort study that included children 0-18 years old with acute bacterial diarrhoea during a 27-year period (1993-2019), in Crete, Greece. Differences in clinical characteristics and pathogen associations were investigated between single and multiple infections.
RESULTS: Two or more bacteria were isolated in stool culture in 53 out of 1932 children (2.74%). Patients with co-infections were younger (p 0.0001) and had higher hospitalisation rates (p 0.03). Escherichia coli (E. coli) was the most prevalent pathogen associated with co-infections, in particular the E. coli enteropathogenic strains O127 and O111 (p 0.001), and Salmonella spp the least (p 0.001). Co-occurrence analysis revealed two positively associated pathogen pairs, E. coli with Campylobacter spp and E. coli (p 0.001) with Salmonella spp (p 0.04).
CONCLUSION: Bacterial enteropathogen co-infection was most common with E. coli strains and related to higher hospitalisation rates and younger age.
