Acquisition risk of multi-drug resistant bacteria and gastrointestinal pathogens on deployment

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.
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.
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.
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.
