Incorrect use of antibiotics is a major cause of antibiotic resistance. In rural Africa, people often receive antibiotics without prescription from local pharmacy shops, increasing the risk of resistance.
Substandard sanitation and hygiene practices result in frequent exchange of bacteria between humans’ guts, and their environment. How important these different sources are for the acquisition of antimicrobial resistant (AMR) bacteria in humans is still unclear, but contacts between humans and animals, in particular rodents, are frequent in much of Africa.
We will develop and evaluate a behavioural intervention for community pharmacy staff and their communities, to improve antibiotic use and hygiene practices, to ultimately reduce AMR. The intervention will be implemented over 12 months in Burkina Faso and DR Congo. We’ll measure as primary result changes in the use of specific AMR-prone and clinically vital antibiotics at community pharmacies throughout the intervention period. We will compare antibiotic use in pharmacies and surrounding communities where the intervention was implemented, and where the intervention did not take place. Also, we will assess changes in hygiene practices by surveying members of the surrounding communities. Then, we will determine how frequent AMR bacteria are transmitted by repeatedly analysing stool samples of those populations, and of rodents living in the surroundings, for bacteria and specific AMR genes. Through mathematical modelling we will quantify how changes in antibiotic use and hygiene practices will impact AMR transmission.
