Introduction: if hygiene conditions are poor during military deployments, soldiers are at risk of fecal-oral acquisition of enteropathogenic microorganisms. Further, stays in high endemicity settings bear the risk of colonization with multi-drug resistant bacteria. Accordingly, respective assessments were performed with German soldiers returning from deployment during returnee screenings at the Department of Tropical Medicine, German Armed Forces Hospital of Hamburg.

Methods: stool samples of returnees and diseased soldiers on deployment were screened by real time PCR for enteropathogenic microorganisms and by cultural approaches for multi-drug resistant bacteria.

Results: during acute episodes of diarrhea, diarrhea-associated Escherichia coli dominated as causative agent in European soldiers in tropical Mali. In contrast, Giardia duodenalis was the most important pathogen in returned German soldiers 8-12 weeks after deployment in Sudan. At this time point after various deployments, colonization rates with multi-drug resistant bacteria like ESBL-producing Enterobacteriaceae were also comparably low as in the healthy German population. On deployment, in contrast, respective colonization rates are considerably higher.

Conclusion: the spectrum of detectable agents varies depending on the time of assessment. While both pathogenic and resistant bacteria can be predominantly found on deployment, persisting protozoa seem to be a medical concern on the long term.
