Carriage of antimicrobial resistance genes in children enrolled in the FIEBRE study
Antibiotic resistance (or antimicrobial resistance: AMR) is a well-recognised threat to global health. Few studies have examined how frequently people in Africa carry bacteria with genes that confer resistance to different antibiotics. The limited data available suggest that the rate of carriage of bacteria with resistant genes is high, even when the antibiotics in question are not widely available locally. There are unanswered questions as to where these genes have come from: previous antibiotic use (either prescribed or over-the-counter); environmentally from the hospital or community, or from eating food where antibiotics have been used in production. We also do not know how often carrying bacteria with AMR genes leads to disease, and whether this leads to a worse outcome for African children.
This study aims to investigate how often children with fever attending inpatient and outpatient facilities in Zimbabwe carry AMR bacteria, whether this relates to the cause of their fever, and leads to worse outcome. I will compare rates of AMR bacterial carriage before and after admission (for inpatients) and with community controls. In a small number of samples, I will analyse and compare AMR genes within bacteria, to see if I can map the spread of particular genes in hospitals and communities, and to explore where the genes may have come from. This study is planned to produce initial data for a wider study in collaboration with vets and geographers looking at the spread of AMR genes in Zimbabwe, and what can be done to prevent that spread.
