Evaluation of the Impact of Oral Ivermectin on Musca Sorbens Flies, Putative Vector of Trachoma

Sponsor: London School of Hygiene and Tropical Medicine

Summary

Trachoma is caused by repeated Chlamydia trachomatis infection in the eye. Routes of infection include close person-to-person contact and contaminated clothing. In addition, the bazaar fly Musca sorbens has been implicated in transmission. These flies frequently visit the faces of children and have been found positive for C. trachomatis, which may be transferred from the body of the flies or their regurgitated or defecated material. This study aims to give recruited healthy volunteers a safe dose of oral ivermectin. Their faeces will be collected over subsequent days to determine whether ivermectin excreted from the body results in faecal concentrations that are high enough to prevent emergence of M. sorbens developing in faeces. It will also quantify ivermectin concentrations in tears secretions and faecal samples for up to 30 days post-treatment.
