Group/Cohort Intervention/treatment
Trichuris trichiura eggs
One healthy volunteer
Biological: Trichuris trichiura eggs
Live eggs from human whipworm, Trichuris trichiura

Primary Outcome Measures :
  1. Faecal egg excretion [ Time Frame: 30 weeks ]
    Weekly monitoring of fecal egg counts by microscopy

Secondary Outcome Measures :
  1. Mucosal T cell associated cytokines [ Time Frame: Week 15 ]
    Biopsy sampling during established infection

  2. Systemic immune parameters (eosinophilia, Subtypes of circulating T cells) [ Time Frame: 30 weeks ]
    Weekly monitoring

  3. Adverse events [ Time Frame: 30 weeks ]
    The included individual was monitored clinically every week for the development of diarrhea and weight loss, and by blood samples for anemia and inflammatory parameters every other week.

Biospecimen Retention:   Samples With DNA
