An international interdisciplinary project led by EPI investigator Arie Havelaar seeks to identify bacterial causes of enteric dysfunction and chronic gut inflammation in Ethiopian children. By studying complex interactions between livestock and people, the project aims to identify reservoirs and exposure pathways by which Campylobacter bacteria colonize kids. But interventions are the ultimate goal.
A new study published in Nature Microbiology reveals that bacteria present in different regions of the gastrointestinal tract either enhance or block murine norovirus infections. The startling findings expand our understanding of how the virus interacts with both its host immune system and the intestinal microbiome, which may one day be useful for developing an antiviral therapy.
