Making Innovation a Reality – Africa Health Initiative (MIRAHI)

What is MIRAHI?

Why Decipher and Diaxxo?

Who is behind MIRAHI?

  • MIRAHI is an initiative to support Innovators have an impact on Healthcare challenges in Sub-Saharan Africa with a focus on Swiss technologies
  • MIRAHI brings together entrepreneurial innovators and the healthcare system to explore what challenges exist and help validate if the entrepreneurial solutions can have an impact and explore further ways to develop them

  • Decipher had interest and competence in AMR monitoring and engaging with the public and healthcare system in Ghana.
  • Diaxxo had a technology that could make an impact on AMR and other challenges but which had not been validated in African conditions.
  • In addition it was possible to engage the local academic ecosystem

Regional Distribution of E. coli ESBL Genes

E. coli ESBL ARG Distribution in Hospital, Animal and Environmental wastewater

12

How significant are these E. coli ESBL ARG distributions: in sources of water

  • Samples collected from the hospitals are more likely to test positive to GES as compared to samples from the environment.

  • Also, samples that tested positive for GES & TEM are more likely to be collected at the hospital setting as compared to samples collected from the environment.

How significant are these E. coli ESBL ARG distributions: in the Regions

There is no statistical significance between the regions and the E. coli ESBL ARGs

What does this data mean?

  • The co-colonization of E. coli with ESBL-TEM & GES in animals (a major food system) is a worrying observation.
  • ESBL-TEM (prevalent in clinical E. coli) found in hospital wastewater and animal wastewater is an indication of environmental spillover of ESBL-TEM.
  • The emergence of ESBL-GES in E. coli obtained from hospital wastewater.
    • ESBL-GEM is a resistance prevalent in P. aeruginosa.
