ESBL in Patients Returning to Sweden With Traveller's Diarrhoea

ESBL-producing Enterobacteriaceae in Patients With Traveller's Diarrhoea- a Prospective Cohort Study.

Patients with traveller's diarrhoea frequently harbour Extended Spectrum Betalactamase (ESBL)-producing Enterobacteriaceae (EPE) returning from EPE-endemic areas.

This study investigates to what extent travellers returning to Sweden with traveller's diarrhoea carry ESBL in their stool. The isolates are examined further according to species, phenotype, antibiogram and whole genome sequencing.

Samples sent to the department of clinical microbiology in Lund, Sweden for culture of salmonella, shigella, yersinia or campylobacter are also cultured selectively for ESBL.

All patients are contacted by mail with the results. ESBL-positive patients are invited to submit further faecal cultures and blood samples during one year follow up time, to investigate how long the patient is colonized with ESBL.
